Inpatient Hospital Review Program (IHRP)
The IHRP requires that some inpatient hospital admissions be authorized through the ColoradoPAR program. This authorization is for the institutional claim (UB-04). Professional claims (CMS 1500) associated with the admission may need authorization separately depending on the service.
For information regarding the PAR program including policy and How-to Guides, visit the ColoradoPAR web page.
For information regarding Inpatient Hospital Review Program, visit the IHRP 2.0 web page.
Inpatient/Outpatient Hospital Billing Information
Both inpatient and outpatient hospital services are a benefit of Health First Colorado when medically necessary and supervised by a physician. Non-emergency outpatient services are subject to Primary Care Physician Program guidelines. The Department of Health Care Policy and Financing (the Department) periodically modifies billing information. Therefore, the information in this manual is subject to change, and the manual is updated as new billing information is implemented. Providers should refer to the Code of Colorado Regulations, Program Rules (10 C.C.R. 2505-10) for specific information when providing hospital care.
Inpatient Hospital Billing Information
Inpatient Hospital Services means preventive, therapeutic, surgical, diagnostic, medical and rehabilitative services that are furnished by a hospital for the care and treatment of Inpatients and are provided in the hospital by or under the direction of a physician.
Inpatient means a person who is receiving professional services at a hospital, the services include a room and are provided on a continuous 24-hour-a-day basis. Generally, a person is considered an Inpatient by a physician's order if formally admitted as an Inpatient with the expectation that the member will remain at least overnight and occupy a bed even though it later develops that the member can be discharged or transferred to another hospital and does not actually use a bed overnight.
Inpatient Hospital Services are reimbursed by Health First Colorado on a prospective basis using a Diagnosis Related Group (DRG) method. Claims with a discharge date on or after January 1, 2014, will be reimbursed using the All-Patient Refined Diagnosis Related Group (APR-DRG).
- Effective July 1, 2016, the Department updated the payment methodology to APR-DRG version 33 for discharge dates after October 1, 2015.
- Effective June 1, 2015, the Department updated the payment methodology to APR-DRG version 32 for discharge dates after January 1, 2014.
- Effective January 1, 2014, APR-DRG version 30 became the reimbursement methodology for all claims with dates of discharge on or after January 1, 2014.
Summary of Inpatient Hospital claims grouper versions based on discharge date
Discharge Date | Grouper |
July 1, 2016 to current | APR-DRG Version 33 |
January 1, 2014 to June 30, 2016 | APR-DRG Version 32 |
October 1, 2006 to December 31, 2013 | CMS-DRG Version 24.0 + annual crosswalks |
Date of Discharge
The day of discharge or death is not counted as a covered day unless discharge or death occur on the day of admission. If admission and discharge or death occur on the same day, the day is considered a day of admission and counts as a full day unit. This includes if a patient is discharged or dies after admission, but before assignment to a room. Charges for ancillary services on the day of discharge or death are covered. Please refer to the Bundling section of this manual.
Interim Payments for DRG Hospitals with Long-Term Inpatient Stays
The Health First Colorado APR-DRG payment system requires that claims for inpatient stays in DRG Hospitals be submitted after discharge. To accommodate the financial needs of DRG Hospitals when long-term stays create large account receivables, DRG Hospitals may bill interim claims using adjusted claims.
Criteria
Criteria
The following criteria must be met in order to receive an interim payment:
- Health First Colorado must be the primary payer. Interim payment is not permitted when the recipient has other medical resources such as Medicare or commercial health insurance coverage.
- Patient status for interim claims must be "30: Still a patient." A final interim claim can only be filed after patient discharge.
After the first interim payment, additional requests should be submitted when Health First Colorado reimbursement reaches or exceeds an additional $100,000 from original Interim Claim.
Billing Process
Submit the first interim claim and submit adjustments to the first interim claim until discharge:
All interim claims should be submitted directly to the Department's fiscal agent.
First interim claim (type of bill 112 - First Interim Claim) should be billed by the hospital for the services performed from the admission date through the billing date with patient status.
Additional interim adjustment claims (type of bill 117 - Hospital Inpatient (Including Medicare Part A)- Replacement of Prior Claim) should be billed by the hospital when the total Health First Colorado payment is at least $100,000 more than the previous interim payment. Interim adjustment claims must cover the entire stay from the first date of service through the billing date.
Final interim claim (type of bill 117 - Hospital Inpatient (Including Medicare Part A)- Replacement of Prior Claim) should be billed after the member has been discharged and should cover the entire stay from the first date of service through the discharge date.
If a hospital chooses to interim bill using type of bill 113-114 then the provider must void previous interim claims prior to submitting additional interim claims or the final interim claim.
Billing for Services Rendered in a Distinct Part Unit
Health First Colorado does not currently recognize Distinct Part Units (DPUs) as separate from the General Hospital under which they are licensed and does not enroll DPUs separately. Admissions to DPUs are for psychiatric care, or rehabilitation care in the General Hospital. The Medical Assistance Program payment to the General Hospital for these cases is designed to cover the cost of these services. Since Health First Colorado does not recognize DPUs, hospitals may not submit two claims for a member who is admitted to a General Hospital and then transferred to the hospital's DPU. A single claim should be submitted for this scenario covering the dates of service from the admission to the general acute facility through the discharge from the DPU. The DPU NPI should be represented as a service location on the claim.
Maternity and Newborn Billing
For claims in which the mother's discharge date occurs on or after July 1, 2020:
Services for the mother and baby must be billed on separate claims under the identification number of each client per 10 CCR 2505-10 8.300.3.A. Information regarding the impact this billing process may have on payment can be found in the March 6, 2020, Hospital Engagement Meeting and the Inpatient Hospital Rates web pages. Unless otherwise medically necessary, charges for a newborn remaining in the hospital are not a benefit (e.g., placement).
For claims in which the mother's discharge date occurs prior to July 1, 2020:
Do not show nursery days in form locator (FL) 6. Nursery days are entered as units on a detail line but are not covered days that represent additional payment. There is no additional inpatient benefit for routine newborn hospitalization. Charges for a well newborn remaining in the hospital after the mother's discharge are not a benefit (e.g., placement). Benefits apply under the following conditions:
- If the mother is in the hospital, the mother's and baby's charges (procedure and diagnosis codes) are billed on one claim as one stay.
- The interChange System cannot accept a baby's birth weight, the weight must be coded using an ICD-10 diagnosis code.
- Baby remains in hospital for placement. This is not a Health First Colorado benefit. Services may be billed on the mother's claim until the time the mother is discharged.
- Mother is discharged, but the baby remains in hospital and is not transferred to another hospital (e.g., baby is not well):
- Baby should be billed separately from the mother
- Baby requires its own Health First Colorado ID number
- The admission date on the baby's hospital claim is the date of the mother's discharge
- Baby's charges, procedure and diagnosis codes related to baby's extended stay, beginning with mother's date of discharge through baby's discharge are billed separately from the mother's charges
- Including a newborn/live (Z38, Z38X OR Z38XX) as a primary diagnosis on the baby's independent claim may cause the claim to be ungroupable and result in an appropriate denial. The primary diagnosis should reflect the reasons why the child remains in the hospital after mother leaves.
- If the baby is transferred to a different hospital, the Health First Colorado benefits are still applicable. The baby's charges (procedure and diagnosis codes) must be billed separately by the receiving hospital.
- Baby should be billed separately from the mother
- When the mother is not eligible for benefits, the baby's well-baby care charges may be billed under the following conditions:
- The baby is eligible for benefits
- The baby has its own Health First Colorado ID number
- If the mother's insurance pays for any portion of the well-baby care, the payment must be included on the claim as a third party payment
Special Instructions for Labor and Delivery Claims
Delivery is a benefit for recipients of Emergency Medicaid, but sterilization is not a covered service for recipients of Emergency Medicaid. If sterilization is performed in conjunction with the delivery for a recipient of Emergency Medicaid, the coding and charges for sterilization must be omitted from the claim. Only the codes and charges for the delivery can be billed.
Newborn Hearing and Metabolic Screenings
Costs associated with the Newborn Hearing Screening and the initial Newborn Metabolic Screening are included in the delivery DRG calculation or the birthing center facility payment. They may not be billed separately.
Current Procedural Terminology (CPT)/ Healthcare Common Procedure Coding System (HCPCS) codes for the Newborn Hearing Screening cannot be billed for dates on or during the date span of the delivery stay. Refer to the Audiology Billing Manual or the Laboratory Billing Manual for more information.
Special Instructions for Labor and Delivery Claims
Delivery is a benefit for recipients of Emergency Medicaid, but sterilization is not a covered service for recipients of Emergency Medicaid. If sterilization is performed in conjunction with the delivery for a recipient of Emergency Medicaid, the coding and charges for sterilization must be omitted from the claim. Only the codes and charges for the delivery can be billed.
Billing for Immediate Post-Partum Long-Acting Reversible Contraceptives (IPP-LARCs)
Effective January 1, 2020, IPP-LARC devices inserted in a DRG Hospital may be reimbursed at the fee schedule rate or the amount billed, whichever is less. Delivery DRG weights (540, 542 & 560) were reduced by .004 to allow for this separate payment.
Prior to January 1, 2020, the cost of the IPP-LARC device was included in the All Patient Refined-Diagnosis Related Group (APR-DRG) calculation for the delivery claim.
Reimbursement for IPP LARCs requires submission of both:
- an Inpatient claim - for the DRG payment
- an Outpatient claim - for the IPP-LARC fee schedule payment
The Inpatient Hospital Claim must group to APR-DRG 540, 542, or 560, and include:
- ICD-10 Diagnosis Code for LARC insertion: Z30.430 or Z30.018,
- ICD-10 Surgical Procedure Code for either:
- an IUD insertion: 0UH90HZ, 0UH97HZ or 0UH98HZ, or
- a Contraceptive Implant insertion: 0JHD0HZ, 0JHD3HZ, 0JHF0HZ or 0JHF3HZ.
The Outpatient Hospital Claim:
- Must include:
- the HCPCS for the LARC device: J7296, J7297, J7298, J7300, J7301 or J7307
- the LARC device's affiliated NDC, and
- Both the FP and SE modifiers
- No additional revenue or procedure codes can be present on the claim
- Outpatient claim must be submitted after the affiliated Inpatient claim is paid, and
- Outpatient claim's date of service must be the date of insertion and within the affiliated Inpatient claim's FDOS-TDOS.
Billing for Non-Covered Days
Total days are the total number of days billed on the claim. These days are calculated as the days between Admit and To Date of Service (TDOS). A day on which a patient begins a leave of absence is not counted as a covered day.
Value code 80 and 81 should be used to indicate the quantity of covered and non-covered days during an inpatient stay. The sum of these days should equal the total days on the claim, less the day of discharge.
Occurrence Span Code 74 should be used to report the from/through dates at a non-covered level of care or leave of absence during an otherwise covered stay.
Medicare Part B Only/Part A Exhaust Coverage
Providers should submit a claim to Medicare for any services covered by Medicare.
Health First Colorado pays the Health First Colorado inpatient allowable amount minus the Medicare Part B payment, minus any commercial insurance payment (if applicable) and minus any Health First Colorado co-payment.
Billing Instructions
The crossover claim TOB 12X will be automatically denied and post EOB 1290 (Invalid Type of Bill for the Claim Type).
For the inpatient crossover claim TOB 11X, providers must manually enter the Medicare Part B-Only and Medicare Part A Exhaust payments. Final claim payment should equal the Medicaid inpatient allowable amount less the Medicare payment, commercial insurance payment (if applicable), and any co-payment.
The Provider Web Portal allows providers to use a Part B only/Part A checkbox when billing inpatient crossover claims for members that have TXIX benefits and Medicare Part A benefits are exhausted prior to or during the stay.
Claims can be submitted via paper, interactively via the Provider Web Portal or by batch via Electronic Data Interchange (EDI). See the instructions below for each submission type:
- Paper: In the Payer Name field (form locator 50), enter the payment source code H - Medicare Part B/A Exhaust, followed by name of each payer organization from which the provider might expect payment. At least one line must indicate Health First Colorado. Electronic claims format shall be required unless hard copy claims submittals are specifically prior authorized by the Department. Refer to the General Provider Information Manual, available on the Billing Manuals web page, for further details.
- Provider Web Portal: Refer to the Provider Web Portal Quick Guide -Submitting a Claim with Other Insurance or Medicare Crossover Information, available on the Quick Guides web page.
- EDI: Refer to the Companion Guides available on the EDI Support web page.
Professional Fees
Costs associated with professional services by salaried physicians are included in the hospital's rate structure and cannot be billed separately to the Health First Colorado. Do not bill professional fees (Revenue Codes 0960-0989) for emergency and outpatient services as an institutional claim.
Professional fees for services provided in the emergency room by contract physicians must be billed by the physician as a professional claim (CMS 1500) using the appropriate HCPCS codes. The Health First Colorado payment is made to the physician or physician clinic.
Medicaid and Criminal Justice Involved Populations
For criminal justice involved populations, Health First Colorado will only cover medically necessary inpatient services rendered in a hospital setting. This policy is based on federal regulation in section 1905(a) of the Social Security Act which excludes FFP for medical services for inmates with exception to inpatient care.
Inpatient services for incarcerated individuals are covered when they meet all of the following conditions:
- Occur in an inpatient hospital outside of the correctional facility
- Require inpatient hospitalization for at least 24 hours
- Are provided between the time of inpatient admission and time of inpatient discharge
Health First Colorado cannot cover services for incarcerated individuals that are provided:
- In an outpatient setting
- In an inpatient setting for a stay that lasts less than 24 hours
- On the premises of the prison, jail, or detention center.
The First Date of Service must match the Admission Date and be reflected in interChange to ensure that only the services provided during the covered inpatient stay are included in the claim.
Example 1:
A member is admitted to inpatient care on October 2, 2021, and discharged on October 5, 2021.
- The claim can be submitted to Health First Colorado.
Example 2:
A member is admitted to inpatient care on October 2, 2021, at 6:00 p.m. and discharged on October 3, 2021, at 8:00 a.m.
- The stay is under 24 hours and is therefore not eligible to be submitted to Health First Colorado.
Example 3:
A member is taken to the emergency room on October 2, 2021, but then is admitted as an inpatient on October 3 and discharged on October 5.
- The hospital can only submit a claim to Health First Colorado for the inpatient days.
- On the claim, the First Day of Service and Admit Date will both be October 3, 2021.
Visit the Health First Colorado and Criminal Justice Involved Populations web page for further information on eligibility and billing for criminal justice involved populations.
Out-of-State Inpatient Hospital Services
Non-emergent out-of-state inpatient services must be prior authorized. Inpatient Prior Authorization Requests (PARs) must be submitted via the ColoradoPAR Program. Refer to the General Prior Authorization Requirements section above.
Out-of-state Hospitals are classified as urban or rural. A base rate of 90% of the Colorado urban or rural base rate is used for the purpose of reimbursement calculation under the Health First Colorado APR-DRG and EAPG payment methodologies.
Billing for Combined Stays under the 48-hr Readmission Policy
Effective for dates of service on or after July 1, 2011, if a member is discharged from a hospital and readmitted to the same hospital within 48 hours for symptoms related to, or for evaluation and management of, the prior stay's medical condition, the hospital must bill these admissions as a single hospital stay. The effect of this rule is that the hospital will receive only one payment for what is considered one episode of care.
The following is the correct billing format when billing for combined stays under the 48-hour readmission policy.
Effective for dates of service on or after July 1, 2011, all claims for hospital readmissions in which a member is readmitted to the same hospital within 48 hours of discharge, will be denied unless the readmission is completely unrelated to the first admission. 48 hours is calculated from Discharge Hour (form locator 16 on the first claim) to Admission Hour (form locator 13 on the second claim). This will apply to all claims for second admissions dated July 1, 2011, or later.
Example 1:
A member is admitted January 19, 2012, and is discharged January 23, 2012, at 2 a.m. The member is readmitted January 25, 2012, at 1 a.m, and is discharged January 28, 2012.
- The hospital bills from DOS January 19, 2012, through DOS January 28, 2012. The number of covered days is seven. The number of non-covered days is two.
- Covered days must be reported using Value Code 80
- Non-covered days, must be reported using Value Code 81
- Claim details need to include leave of absence Revenue Code 0180, the units should equal to the non-covered days and charges equal to a non-zero amount
Example 2:
A member is admitted January 19, 2012, and is discharged January 23, 2012, at 2 a.m. The member is readmitted for an unrelated reason on January 25, 2012, at 1 a.m, and is discharged on January 28, 2012.
- The hospital bills two separate claims for each stay
- The second claim must include condition code B4
Example 3:
A member is admitted January 19, 2012, and is discharged January 23, 2012, at 2 a.m. The member is readmitted January 25, 2012, at 4 a.m, and is discharged January 28, 2012.
- The hospital bills two separate claims for each stay
The Colorado interChange System will automatically deny subsequent claims for readmissions to the same hospital within 48 hours. Providers will have to submit an adjustment claim to correctly reflect the dates of service for the full episode of care. To indicate that a readmission is completely unrelated to the first admission, a claim may be coded with condition code B4 which will allow the separate episode of care.
A claim example is provided under "Billing for combined stays under the 48-hour readmission policy".
The Department's audit team will continue to retrospectively review all readmissions within 48 hours which are paid with use of condition code B4. If the Department determines that the readmission is related to the first admission, the Department will recoup payment.
Health First Colorado does not recognize Distinct Part Units (DPUs) or any other units of a hospital separately from the General Acute Care Hospital under which they are licensed. General Acute Care Hospitals may not submit two claims for a member who is transferred between units of a hospital. A single claim should be submitted covering the dates of service from the admission to the General Acute Care Hospital through the discharge from the DPU. When the Department's audit team identifies claims for such transfers, the second admission will be denied. Stays at Transitional Care Units or any other location that is not part of the hospital are not billable under the hospital's Health First Colorado provider number and will be denied if billed as such.
Late Charges
Late charges for claims may be submitted as an adjustment to the fiscal agent of the Department at any time during the initial timely filing period.
When claims are adjusted, for any reason, outside of the timely filing period the claim will deny for being outside of timely filing and the entire original payment for the claim will be recouped.
Adjustments for Overpayments
Under Section 1128J(d) of the Social Security Act, any provider who receives an overpayment needs to report and return the overpayment to the Department within 60 days of identification. There are two different ways this can be completed, including through the provider portal or by making a self-disclosure.
If a provider realizes that it has received an overpayment, the provider can adjust the claim through the provider portal. When a claim is adjusted in the provider portal a new ICN is generated and will be processed against the edits in the claims processing system. One of these edits is the timely-filing edit, which will deny any claim where timely-filing has not been preserved. If a provider adjusts a claim through the provider portal and the claim is outside of timely-filing, the claim will deny and the amount paid on the original claim will be recouped. The Department does not issue waivers of timely filing in order to reverse these recoupments.
If a provider received an overpayment and the claim is outside of timely-filing, the correct way to address this is to submit a self-disclosure. The self-disclosure process requires the provider to identify the claims at issue and the reason for the overpayment. In order to return the money to the Department, the provider may either direct the Department to set up an accounts receivable in the claims processing system so that the amount can be deducted from future payments, or to submit a check to:
Department of Health Care Policy and Financing
ATTN: Audits and Compliance Division
1570 Grant St.
Denver, CO 80203
More information on the Self-Disclosure process can be found on the Self-Disclosure Information web page.

Behavioral Health Services
Non-Psychiatric Hospitals
Outpatient Psychiatric Services:
Psychiatric services, including prevention, diagnosis and treatment of emotional or mental disorders, are Medicaid benefits at Non-Psychiatric Hospitals as noted in the Hospital Services Rule at 8.300.3.B.2.
Psychiatric Hospitals
Inpatient Psychiatric Hospital Services:
Inpatient Hospital Psychiatric Services are a Medicaid benefit for individuals age 20 and under when provided as a service of an In-Network Hospital as noted in the Hospital Services Rule at 8.300.3.A.4.
Inpatient Psychiatric Hospital Services are a benefit only when:
- Services involve active treatment which a team has determined is necessary on an Inpatient basis and can reasonably be expected to improve the condition or prevent further regression so that the services shall no longer be needed, the team must consist of physicians and other personnel qualified to make determinations with respect to mental health conditions and the treatment thereof, and
- Services are provided prior to the date the individual attains age 21 or, in the case of an individual who was receiving such services in the period immediately preceding the date on which he/she attained age 21, the date such individual no longer requires such services or if earlier, the date such individual attains age 22.
Outpatient Psychiatric Hospital Services:
Outpatient services are not a Medicaid benefit in Psychiatric Hospitals.
Billing for Psychiatric Hospital Inpatient Services - non-SUD
Inpatient services provided to Health First Colorado members in Psychiatric Hospitals are reimbursed on a per diem basis. The per diem rates follow a step-down methodology based on revenue code. Revenue codes can be found in Appendix Q, located on the Billing Manuals web page under the Appendices drop-down menu.
Step 1 (Revenue Code 114): day 1 through day 7
Step 2 (Revenue Codes 124 and 134): day 8 through remainder of care at acute level
Interim Billing Instructions for Psychiatric Hospital Inpatient Services
Psychiatric Hospitals may bill on an interim basis for services.
A new claim should be submitted for each span of time billed for with the Admit date representing the original date of admission, FDOS representing the first date of service on the claim being submitted and the TDOS representing the last date of service on the claim.
For example, if a provider bills on a monthly basis and the member's admission was on 2/1/2019, the first claim should have the following:
Admit date: 2/1/2019
FDOS: 2/1/2019
TDOS: 2/28/2019
Revenue code 114 should be used for day 1-7
Revenue code 124/134 should be used for day 8-28
The second claim submission for the following month should have the following:
Admit date: 2/1/2019
FDOS:3/1/2019
TDOS: 3/31/2019
Revenue code 124/134 should be used for all days on this claim
Obtaining Authorization for Behavioral Health Services
All Health First Colorado members are assigned to a Regional Accountable Entity (RAE) which is responsible for approval and reimbursement of behavioral health services. Services rendered prior to a member's assignment to a RAE should be billed Fee-for-Service to Health First Colorado and are subject to Fee-for Service policies. A RAE may refer a member to a hospital for either inpatient or outpatient services. At the time of referral, the RAE will provide the hospital prior authorization and personal health information for the member as necessary.
If a member is referred to a hospital by a RAE, all information necessary for billing will be provided. If a member presents at a hospital requesting services, the hospital will need to submit an eligibility inquiry to verify the member's RAE. The hospital will then contact the RAE in order to obtain prior authorization for treatment.
When a member presents at a hospital requesting emergency behavioral health services, the hospital provider will be reimbursed by the RAE for medical stabilization of the member but must contact the RAE to coordinate any further services.
Refer to the Health First Colorado UB-04 Revenue Code Table (Appendix Q) for a complete listing of services and the corresponding valid revenue codes.
Refer to Appendix Q located on the Billing Manuals web page under the Appendices drop-down.
If the claim has been denied by the RAE for non-included services, providers may appeal the decision. Appeal information is listed on the denial letter from the RAE.
Billing for Substance Use Disorder (SUD) Services
For claims in which the discharge date is prior to January 1, 2021: Inpatient substance use disorder (SUD) services are not a covered benefit.
Individuals age 20 and under may access these services through Early and Periodic Screening, Diagnostic and Treatment (EPSDT). Services must be provided by facilities that attest to having in place rehabilitation components required by the Department. These facilities must be approved by the Department to receive reimbursement. The Department will review the claims submitted under APR-DRG 772 regularly to ensure only providers that have an attestation with the Department are being reimbursed for these services.
For claims in which the discharge date occurs on or after January 1, 2021:
Inpatient SUD services are a covered benefit for members with a primary SUD diagnosis when medically necessary as determined by the American Society for Addiction Medicine (ASAM) Criteria. Inpatient SUD services are billed using the following accommodation revenue codes:
Revenue code 1000 - ASAM Level 3.7: Medically Monitored Intensive Inpatient Treatment
Revenue code 1002 - ASAM Level 3.7WM: Medically Monitored Inpatient Withdrawal Management
Reimbursement for Inpatient SUD services includes behavioral health treatment, medical treatment, and room and board. Coding pages and more information about residential and inpatient SUD services can be found in the Provider Manual for Residential and Inpatient Substance Use Disorder Services.
Hospitals must maintain an accurate count of all beds in their facility in the interChange Web Portal. Bed counts should include all beds in a facility regardless of whether they are utilized for psychiatric or SUD stays.
Non-Psychiatric Hospitals
SUD services are covered in non-psychiatric hospitals for members of all ages.
Inpatient SUD services provided to Health First Colorado members in non-psychiatric hospitals are reimbursed using the methodology assigned to them (APR-DRG, Per Diem, etc.). The following accommodation revenue codes should be used for claims in which the member's primary diagnosis is a substance use disorder. Using these accommodation codes allows for the services to be identified as SUD services.
Revenue code 1000 - ASAM Level 3.7: Medically Monitored Intensive Inpatient Treatment
Revenue code 1002 - ASAM Level 3.7WM: Medically Monitored Inpatient Withdrawal Management
Psychiatric Hospitals
SUD services are covered in psychiatric hospitals for members age 21-64.
Inpatient SUD services provided to Health First Colorado members in Psychiatric Hospitals are reimbursed on a per diem basis. The per diem rates are identified based on revenue code. Revenue codes can be found in Appendix Q, located on the Billing Manuals web page under the Appendices drop-down menu.
Revenue code 1000 - ASAM Level 3.7: Medically Monitored Intensive Inpatient Treatment
Revenue code 1002 - ASAM Level 3.7WM: Medically Monitored Inpatient Withdrawal Management
Individuals age 20 and under may access these services through Early and Periodic Screening, Diagnostic and Treatment (EPSDT). Services must be provided by facilities which attest to having in place rehabilitation components required by the Department. These facilities must be approved by the Department to receive reimbursement. The Department will review the claims submitted under APR-DRG 772 regularly to ensure only providers that have an attestation with the Department are being reimbursed for these services.
Hospital Service Payments - Inpatient Reimbursement
Hospitals designated as Prospective Payment System (PPS) Hospitals and Pediatric Specialty Hospitals are paid using the Diagnosis Related Group (DRG) methodology. Each hospital is assigned a base reimbursement rate which is calculated to represent the average cost per discharge for Health First Colorado members. New hospitals, critical access hospitals or low-discharge hospitals are assigned the peer group average base rate according to their in-state/out-of-state and urban/rural designations. Each DRG is assigned a relative weight.
DRG Base payment is calculated as the hospital base rate multiplied by the DRG relative weight.
Outlier payments: If a hospital stay exceeds the DRG trim point, outlier days are calculated for additional payment at 80% of the established DRG per diem.
Outlier Payment Logic:
- Outlier Days = Covered Days beyond DRG Trim Point
- Outlier Payment = Outlier Days * Per Diem * 80%
Transfers: If the member is transferred from one hospital to another, both facilities are paid a DRG per diem rate up to the maximum reimbursement under the appropriate DRG, based on the length of stay. Both hospitals receive outlier day payments, if applicable. Long-Term Acute Care and Rehabilitation Hospitals are excluded from the transfer payment logic. See more specific information below for coding used to identify transfers and calculations for payment.
Cutback Payment for Uncovered Days During Stay: If there are days during the inpatient stay where the member does not have coverage under Health First Colorado, the hospital will be paid a DRG per diem rate up to the maximum reimbursement under the appropriate DRG, based on the length of stay. The hospital will also receive outlier day payments, if applicable.
Cutback Payment Logic:
- IF Covered Days <, DRG Average Length of Stay, THEN pay (Per Diem * Covered Days)
- IF Covered Days >,= DRG Average Length of Stay, THEN pay DRG Base Payment
Psychiatric Hospitals: Hospitals designated as Non-Prospective Payment System (NPPS) Hospitals are reimbursed at an established per diem rate.
Out of State Hospitals: Urban or Rural Out-of-State Hospitals are paid using the DRG methodology. Reimbursement is made using a base rate of 90% of the average Colorado urban or rural base rate.
Medicare Crossover Claims: Medicare crossover claims are reimbursed by the Health First Colorado program based on whichever of the following two formulas results in a lesser amount:
- The sum of the reported Medicare coinsurance and deductible
- The Health First Colorado-allowed benefit minus the Medicare payment
Transfer Payment Logic
In situations where an inpatient member is transferred to or from a General Hospital (patient discharge status codes 02, 05, 62, 63, 66, 69, 82, 85, 90, 91, or 94 OR admit source 4), the General Hospital will be reimbursed on a per diem basis if the member's covered days are less than the DRG Average Length of Stay (ALOS). The General Hospital is also eligible to receive outlier payments if the member's covered days exceeds the DRG Trim Point (see outlier calculation above). Otherwise, the DRG Base payment is paid for covered days equal to or greater than the ALOS and less than or equal to the DRG Trim Point.
Per Diem Calculation:
- Per Diem = DRG Base Payment √∑ DRG Average Length of Stay
Transfer Payment Logic:
- IF Covered Days <, DRG Average Length of Stay, THEN pay (Per Diem * Covered Days)
- IF Covered Days >,= DRG Average Length of Stay, THEN pay DRG Base Payment
Long-Term Acute Care and Rehabilitation Hospitals are excluded from the transfer payment logic.
When transfer services are billed, complete the following Form Locators for correct reimbursement calculation:
Form Locator 15, Source of Admission (04)
Form Locator 17, Patient Status (02, 05, 62, 63, 66, 69, 82, 85, 90, 91, or 94)
See the instructions for each Form Locator in this provider manual.
"Lower of" Pricing
The Department has the obligation to pay "lower of" pricing based on providers' customary charges, also known as the providers' submitted charges, on the claim. Federal regulations require that payment for Inpatient Hospital Services not exceed providers' customary charges. See 42 CFR § 447.271. Likewise, Colorado's State Plan includes an attestation that the Department "meets the requirements of 42 CFR Part 447, Subpart C, and sections 1902(a)(13) and 1923 of the [Social Security] Act with respect to payment for Inpatient Hospital Services." See § 4.19(a) Payment for Services.
"Present on Admission" Indicator on Hospital Claims
Inclusion of "present on admission" (POA) indicator responses are required for inpatient hospital claims submitted through the Web Portal. The Department's policy follows that of the Medicare program for hospitals paid through prospective payment.
The POA response is required for Principal Diagnosis and all Other Diagnoses. It is not required for the Admitting Diagnosis. The POA response is to be documented in the gray area to the right of Form Locator 67 (Principal Diagnosis) and 67A -67Q (Other Diagnoses). Allowed responses are limited to:
✓ Y = Yes - present at the time of inpatient admission
✓ N = No - not present at the time of inpatient admission
✓ U = Unknown - the documentation is insufficient to determine if the condition was present at the time of inpatient admission
✓ W = Clinically Undetermined - the provider is unable to clinically determine whether the condition was present at the time of inpatient admission or not
✓ "Blank" or "1" = Diagnosis is exempt for POA reporting or is not submitted ("blank" to be used on electronics submissions, "1" for paper submissions)
The POA indicator is used to identify claims with Health Care Acquired Conditions (HCAC) and Other Provider Preventable Conditions (OPPC). Specific codes associated with HCAC and OPPC are provided below. These are events which if occurred while in the hospital (POA = N or U) can complicate care and member outcomes. Because these events can be deemed preventable, CMS does not allow the Department to pay additional costs of a higher APR-DRG assignment arising from HCACs or must deny payment altogether for OPPCs.
Hospital-Acquired Conditions (HAC)
Refer to the latest CMS Medicare Hospital Acquired Conditions List for the latest ICD-10-CM Diagnosis Codes.
Other Provider Preventable Conditions (OPPC) - FY2013
Other Provider Preventable Conditions (OPPC)
- Surgery performed on the wrong body part
- Surgery performed on the wrong member
- Wrong surgical procedure performed on a member
Hospitals are required to submit claims when any of these HCAC or OPPC events occur in an inpatient hospital setting - and also when an OPPC event occurs in an outpatient healthcare setting. Members may not be billed or balance-billed for services related to these HCACs or OPPCs. The Department will collaborate with hospitals to assure appropriate reimbursement for cases in which a member receives subsequent care for an HCAC or OPPC in a hospital other than the original site in which the event occurred.
Swing Bed Services
Hospitals certified to provide Skilled Nursing Facility (SNF) services and/or Intermediate Care Facility (ICF) services to members in swing beds must furnish the services, supplies and equipment required for SNFs and ICFs within the approved per diem rate. Services must be certified as medically necessary.
Swing Bed services should be billed using a Swing Bed enrollment (Provider Type 20 Specialty Code 396). For details on billing and reimbursement for these services, refer to the Nursing Facility Billing Manual located on the Billing Manuals web page under the UB-04 drop-down menu.
Inpatient Subacute Care During the COVID-19 Public Health Emergency
Inpatient Subacute Care - Hospital
The Department passed an emergency rule on April 23, 2020, to allow hospitals enrolled as General Hospitals (Provider Type 01) to provide Inpatient Subacute Care in their hospital and CDPHE approved alternate care sites during the COVID-19 Public Health Emergency. On May 20, 2020, the Department received approval from the Centers for Medicare & Medicaid Services (CMS) for a corresponding State Plan Amendment (SPA) #20-0012 allowing Inpatient Subacute Care.
What is Inpatient Subacute Care?
Inpatient Subacute Care is equivalent to the medically necessary level of care administered by a skilled nursing facility (SNF) for skilled nursing and intermediate care services as defined in 10 CCR 2505-10, Sections 8.406 and 8.409.
When can a hospital provide Inpatient Subacute Care?
- If the member requires the level of care that would normally be provided by a SNF, but they cannot or should not be transferred to a SNF,
- the hospital may provide Inpatient Subacute Care.
- If the member requires the level of care that would normally be provided by a SNF, but they cannot or should not be transferred to a SNF and the hospital does not have capacity, the member may be transferred to a,
- CDPHE approved alternate care site, or,
- another hospital that can provide Inpatient Subacute Care.
- Members may be admitted to Inpatient Subacute Care,
- after an inpatient admission,
- from an emergency department,
- from observation status, or,
- by primary care referral to the administering hospital.
When can't a hospital provide Inpatient Subacute Care?
- If the member's principal diagnosis is a RAE-covered mental health diagnosis,
- the hospital is a Psychiatric Hospital (Provider Type 02), or,
- the Public Health Emergency has ended.
Where can Inpatient Subacute Care be provided?
Inpatient Subacute Care can be provided in the following locations:
- a hospital, or,
- a hospital's CDPHE approved alternate care sites.
What payment methodology is used for Inpatient Subacute Care?
Inpatient Subacute Care is paid at a per diem rate of $235.
If a hospital has designated swing beds, the hospital should continue to provide services as swing beds and will be paid under their existing per diem rate.
How does a hospital bill for Inpatient Subacute Care?
Claims for Inpatient Subacute Care with dates of service on or after April 24, 2020, through the end of the federal Public Health Emergency, may be submitted to the Department for reimbursement.
Hospitals must submit a separate inpatient or inpatient crossover claim for covered Inpatient Subacute Care days using Revenue Code 190 (Subacute Care). No other revenue codes should be present on this claim. If the member was moved from an inpatient hospital stay to Inpatient Subacute Care then Patient Status 70 (discharged/transferred to another type of health care institution not defined elsewhere in this code list) should be used as the patient status on the claim for the inpatient hospital stay. The claim for the inpatient hospital stay will be paid using the hospital's current inpatient payment methodology, if a different patient status code is used, transfer pricing may apply.
If the patient received services at a CDPHE approved ACS, then the location of the ACS should be submitted as the service facility provider on the claim. If the ACS is not an enrolled provider with the Department, the claims will need to be submitted through batch as an 837i standard x12 HIPAA transaction.
Inpatient Subacute Care services billed with any revenue code other than 190 or a RAE-covered mental health principle diagnosis, will be denied for Explanation of Benefits (EOB) 3255 - Inpatient lower level of care service billed with conflicting services.
Claims should be submitted to the appropriate Managed Care Organization (MCO) when the member is enrolled in a Managed Care Plan.
Outpatient and CC/FSED
Outpatient Hospital Services means preventive, diagnostic, therapeutic, rehabilitative, or palliative services that are furnished to Outpatients, and are furnished by or under the direction of a physician or dentist.
Outpatient is defined by professional services at a hospital, which is not providing the member with room and board and professional services on a continuous 24-hour-a-day basis.
Outpatient Service Limitations
Visit the Colorado Medicaid State Plan web page for more information.
Routine and annual physical examinations are not provided unless determined to be medically necessary based upon a medical diagnosis, complaint, or symptom.
Enhanced Ambulatory Patient Grouping System (EAPG)
The Department reimburses hospitals for institutional outpatient claims with all service dates on or after October 31, 2016, using the Enhanced Ambulatory Patient Grouping (EAPG) methodology. As such, periodic updates to cost-to-charge ratios are no longer required. Payment calculation is performed on the claim detail as the lower of redistributed charges or hospital-specific base rate multiplied by the detail's assigned EAPG's Adjusted Relative Weight.
The interChange system relies on the 3M EAPG Grouper module to price outpatient hospital claims. In its pricing calculations, billed amounts are determined as reimbursable or non-reimbursable based on if the revenue code is covered. Refer to Appendix Q, located on the Billing Manuals web page under the Appendices drop-down menu. Reimbursable billed amounts are aggregated by visit, then distributed to each line based on the proportion of that line's EAPG Adjusted Relative Weight to the sum of that line's visit's EAPG Adjusted Relative Weights. The redistributed billed amounts are utilized for the purpose of performing a "lower of" calculation, which will compare that line's redistributed billed amount to its EAPG Payment amount.
Outpatient hospital claims should be billed using Type of Bill 013X (Hospital Outpatient). The EAPG methodology relies on both revenue and CPT/HCPCS codes to price claim details. As such, CPT/HCPCS should be billed whenever possible as appropriate for the services delivered. Please note that this is an update from the requirements of the preceding outpatient hospital payment methodology which required claim details billed with certain revenue codes (036X (Operating Room Services), 045X (Emergency Room), etc.) to have their charges aggregated into a single line without a CPT/HCPCS code.
The Department is currently reimbursing using version 3.16 of EAPG methodology.
Effective Date Range | EAPG Version |
---|---|
October 30, 2016, and prior | N/A |
October 31, 2016, to December 31, 2021 | EAPG version 3.10 |
January 1, 2022, to current | EAPG version 3.16 |
For further information on the Department's implementation of the EAPG methodology, including information on Colorado's EAPG Relative Weights and how to obtain the EAPG Definitions Manual from 3M, visit the Outpatient Hospital Payment web page.
Prior to October 31, 2016, reimbursement for Outpatient Hospital Services was calculated by multiplying the submitted charges by the Medicare Part B cost to charge ratio of the submitting hospital and then by the Health First Colorado cost ratio (subject to change). Outpatient laboratory, occupational therapy, physical therapy, and hospital-based transportation claims were reimbursed based on the lower of submitted charges or Health First Colorado fee schedule.
In-State Billing Providers:
- Reimbursement Amount = Line Item Submitted Charges * Hospital Cost to Charge Ratio * Health First Colorado Cost Ratio
Out-of-State Billing Providers:
- Reimbursement Amount = Line Item Submitted Charges * Hospital Cost to Charge Ratio* Health First Colorado Cost Ratio
Bundling
"Bundling" describes a single reimbursement package for related services. Health First Colorado reimbursement for inpatient hospital care includes associated outpatient, laboratory, and supply services provided in a 24-hour period immediately prior to the hospital admission, during the hospital stay and 24 hours immediately after discharge when billed by the same provider.
Prenatal services provided within 24 hours of an inpatient delivery, observation stays and same location emergency department visits within 24 hours of an inpatient admission are related and should be bundled.
Example: A member is seen in the emergency department on February 11, 2018. The member is admitted as an inpatient on February 12, 2018. The member is discharged on February 20, 2018.
From Date: February 11, 2018
Admit Date: February 12, 2018
Covered (Inpatient) Days: 8 days (February 12, 2018 - February 20, 2018)
Revenue line items and surgical procedure performed on an outpatient day should be reported (From Date), but should not be reported for the accommodation units and inpatient covered days.
Recurring Visits and ED/Observation Billing for Outpatient Claims
Emergency Room visits should not be included on outpatient claims describing recurring visits (regularly scheduled visits for ongoing treatment, such as physical therapy or oncology treatment). Emergency Room visits should be billed separately for the EAPG grouper to calculate payment appropriately per claim and visit. These types of visits are identified by outpatient claims which are billed with Revenue Codes 045X (Emergency Services) or 076X (Specialty Services).
Recurring visits which may include Observation Services should have each visit billed on separate claims to avoid unintended bundling during payment calculation.
EAPG Consolidation and Distinct Procedures
The EAPG reimbursement methodology is utilized to group payment for similar significant procedures when billed on an outpatient hospital claim, such that only the most resource-intensive significant procedure will be payable per visit, as determined by the EAPG algorithm. For payment to be calculated appropriately for separate and distinct significant procedures occurring during the same visit, claim details may be billed with modifier 59 to indicate that they are distinct procedural services. Effective for institutional outpatient claims with a first date of service on or after January 1, 2018, modifiers XE, XP, XS and XU may also be used to indicate distinct procedural services.
Additional Medical Visits
Modifier 27 may be reported for multiple outpatient hospital evaluation and management encounters on the same date for an institutional outpatient claim. Line items billed in this way may be assigned ancillary EAPG 449 (Additional Undifferentiated Medical Visits/Services) and are only payable during visits where no significant procedure has taken place.
Bilateral Procedures
Modifier 50 may be reported on institutional outpatient hospital claim details for bilateral procedures performed during the same operative session. Such procedures must be billed on a single claim detail for reimbursement to be calculated appropriately.
340B Drug Billing
Drugs purchased through the 340B Drug Discount Program must be billed with the UD modifier, which will allow the drug to be priced appropriately by the EAPG software. Drugs purchased in this way must be billed at acquisition cost.
Discarded Portion of Drug Modifier
Discarded portions of drugs provided during an outpatient hospital stay must be billed on a separate line with the JW modifier. These details are not considered payable on an outpatient hospital claim.
Never Event Billing
Modifiers for never events PA (surgery, wrong body part), PB (surgery, wrong patient), and PC (wrong surgery on patient) must be reported when appropriate. These services are not considered payable on an outpatient hospital claim.
Terminated Procedure Reporting
Terminated procedures must be reported with modifiers 52 (reduced services) or 73 (discontinued services prior to anesthesia administration). Reporting with the proper modifier will allow the procedure to be priced appropriately by the EAPG software.
CPT/HCPCS Multiple Units
Billed units should be summed into a single line for each CPT/HCPCs code and date of service. The only exceptions are for required modifiers (e.g. billing two lines for a drug, where the discarded portion of the drug must be billed on a separate line with the JW modifier) or when billing drugs with different NDCs but the same HCPCS. On the lines with the repeated drug HCPCS code, a different NDC must be billed for correct processing..
Outpatient Hospital Specialty Drug Carveout
Payments for certain specialty drugs are carved out of the EAPG methodology for outpatient hospital claims with the first date of service on or after August 11, 2018. The codes for these drugs and the effective dates for their carveout are listed in Appendix Z, located on the Billing Manuals web page under the Appendices drop-down menu. In order to reimburse these drugs, the outpatient claim containing these drugs must be billed with the invoice for these drugs.
Effective July 8, 2022, take-home Naloxone when billed on an outpatient hospital claim with HCPCS G1028 and/or G2215 will be reimbursed at the fee schedule rate.
Outpatient Hospital Unbundled DME Billing
Since the implementation of EAPGs, the Department has carved out the payment for unbundled Durable Medical Equipment from its outpatient claims and requests that such line items are billed on the CMS-1500. Such line items are subject to the billing rules and payment methodology in place for DME Suppliers. Refer to Appendix G, located on the Billing Manual web page under the Appendices drop-down menu, for a listing of the CPT/HCPCS codes which are unbundled from the EAPG methodology.
Inpatient-Only Procedure
The Department uses both CMS and 3M EAPG Inpatient Only lists. The 3M EAPG Inpatient Only List is in Appendix O, located on the Billing Manual web page under the Appendices drop-down menu. Inpatient-only procedures performed in the outpatient setting are denied.
Observation Billing for Outpatient Claims
Observation stays are a covered benefit as follows. Clients may be admitted as Outpatients to Observation Stay status. The billed line for observation must have an observation time between 8 and 48 hours. With appropriate documentation, clients may stay in Observation for more than 24 hours, but an Observation Stay shall not exceed forty-eight hours in length per 10 CCR 2505-10 8.300.3.B.1. A physician orders either Inpatient admission or discharge from observation. An Inpatient admission cannot be converted to an Outpatient Observation Stay after the client is discharged.
The assignment of separate ancillary Observation EAPG is dependent upon specific criteria. This logic is displayed within the Ancillary Observation Processing Logic within the 3M Definitions Manual for 3M Enhanced APG (EAPG) System.
Example 1: HCPCS G0378 is billed with 8-48 billed units on a claim along with a Type 2 Significant Procedure EAPG. Regardless of services billed on the claim, G0378 will be assigned EAPG code 450 and will package.
Example 2: HCPCS G0378 is billed with 8-48 billed units on a claim along with a medical visit AND Type 21-25 Significant Procedure EAPG. G0378 will be assigned EAPG code 450 and not be packaged.
Example 3: HCPCS G0378 is billed and no Type 2 Significant Procedure and no medical visit are present, G0378 will be assigned EAPG 999.
Example 4: HCPCS G0378 is billed and no Significant Procedure and no medical visit are present, but a Type 21-25 Significant Procedure is present, G0378 will be assigned EAPG 450 and will package.
Example 5: HCPCS G0378 is billed with 8-48 billed units on a claim along with a medical visit AND NO Significant Procedure EAPG of any type. G0378 will be assigned EAPG code 450 and not be packaged.
Partial Hospitalizations
When Partial Hospitalization services are delivered by a general acute care hospital and the principal diagnosis is not a RAE-covered mental health diagnosis, the services may be billed fee-for-service using revenue codes 912 and/or 913. A RAE denial is not necessary to process these claims. These revenue codes have been payable through EAPG since 11/20/2019 and the codes were retroactively opened for billing back to 7/1/2018.
Span Billing
Span billing is allowed for outpatient hospitals, rural health clinics and dialysis centers. Enter the beginning and ending dates of service in FL 6. FL 45 must be completed with the correct date of service using MMDDYY format for each line item submitted. Each date of service must be shown on a separate detail line with a revenue code, procedure code, unit(s) and charge.
Split Bills
For any specified date or date span, billed services must appear on a single UB-04 claim. A paper claim cannot be submitted as a two or more part claim. Multiple page claim should be submitted through the portal or electronically.
Outpatient claims that span the end of one calendar year and the beginning of the following year should be split billed by year.
Providers reimbursed an encounter rate or per diem must split bill to accommodate the date of the rate change.
Third Party Payment Pro-rate
When a provider receives a third party lump sum payment for multiple services billed to Health First Colorado on separate claim forms, i.e., hospital stay and transportation, the provider should pro-rate the third party payment to the multiple services/claims.
Each claim must include a copy of the insurance company's explanation of benefits (EOB) or check with a notation that the payment has been applied to multiple claims.
Example (for outpatient and transportation services)
Services incurred were:
Outpatient $ 800.00
Transportation $ 200.00
Total Billed to Third Party Payer $ 1000.00
Lump-sum payment received from Third Party Payer $ 700.00
To pro-rate third party payment for multiple Health First Colorado UB-04 claims, determine what percentage of the total charge is represented by each claim amount. Divide each individual claim charge by the total charge.
Outpatient Services $800.00 ÷ $1,000.00 = 80%
Transportation Services $200.00 ÷ $1,000.00 = 20%
To determine the correct third party payment amount to enter on each claim, multiply each percentage from the previous calculation times the total amount received from the third-party payer.
These amounts should be entered on the Third Party Payer line in FL 54 (Prior Payments).
80% x $700.00 = $560.00 on the Outpatient claim
20% x $700.00 = $140.00 on the Transportation claim
The amount for the Health First Colorado line in FL 55 (Estimated Amount Due) is the difference between the total claim charge and the third-party payer pro-rate amount.
Outpatient $800.00 - $560.00 = $ 240.00
Transportation $200.00 - $140.00 = $ 60.00
Transportation
Effective October 31st, 2016, transportation services can no longer be billed on an institutional claim by the hospital. Hospitals providing transportation must also enroll as a transportation provider. Such services should be billed on a professional claim. Refer to the EMT and NEMT Billing Manuals, located on the Billing Manuals web page under the CMS 1500 drop-down menu and Transporation, for details.
To provide Non-Emergent Medical Transportation (NEMT) and/or Emergency Medical Transportation (EMT) services, hospitals must complete enrollment to become a Health First Colorado transportation provider.
To access the application, visit the Online Provider Enrollment Types web page.

Procedure/HCPCS Codes Overview
The codes used for submitting claims for services provided to Health First Colorado members represent services that are approved by the Centers for Medicare & Medicaid Services (CMS) and services that may be provided by an enrolled Health First Colorado provider.
The Healthcare Common Procedural Coding System (HCPCS) is divided into two principal subsystems, referred to as level I and level II of the HCPCS. Level I of the HCPCS is comprised of Current Procedural Terminology (CPT), a numeric coding system maintained by the American Medical Association (AMA). The CPT is a uniform coding system consisting of descriptive terms and identifying codes that are used primarily to identify medical services and procedures furnished by physicians and other health care professionals. Level II of the HCPCS is a standardized coding system that is used primarily to identify products, supplies, and services not included in the CPT codes, such as ambulance services and durable medical equipment, prosthetics, orthotics, and supplies (DMEPOS) when used outside a physician's office.
Level II codes are also referred to as alpha-numeric codes because they consist of a single alphabetical letter followed by 4 numeric digits, while CPT codes are identified using 5 numeric digits.
HIPAA requires providers to comply with the coding guidelines of the AMA CPT Procedure Codes and the International Classification of Disease, Clinical Modification Diagnosis Codes. If there is no time designated in the official descriptor, the code represents one unit or session.
The Department updates and revises HCPCS code listings through the billing manuals and bulletins. Providers should regularly consult the billing manuals and monthly bulletins on the Billing Manuals web page and Bulletins web page of the Department's website.
To receive electronic provider bulletin notifications, an email address can be entered into the Web Portal in the Provider Data Maintenance area. Bulletins include updates on approved codes as well as the maximum allowable units billed per procedure.
All outpatient laboratory, occupational therapy, physical therapy, x-ray and hospital-based transportation claims must be billed using both HCPCS and revenue codes. Outpatient laboratory, occupational therapy, physical therapy, and hospital-based transportation claims are reimbursed based on the Health First Colorado fee schedule. Outpatient hospital radiology and diagnostic imaging claims are reimbursed based on the hospital cost to charge ratio. For complete policy and requirements for diagnostic imaging and radiology, refer to the Outpatient Imaging and Radiology Billing Manual, located on the Billing Manuals web page under the CMS 1500 drop-down menu.
When submitting claims for transportation, outpatient laboratory, occupational therapy, physical therapy, and radiology to the Health First Colorado, observe the following guidelines:
- Always use the most current CPT revision. Health First Colorado adds and deletes codes as they are published in annual revisions of the CPT.
- Use CMS codes only when CPT codes are not available or are not as specific as the CMS codes.
- Not all codes listed in the annual Health First Colorado HCPCS code publications are benefits of the Health First Colorado. Read the entire entry to determine the benefit status of the item.
The CPT can be purchased at local university bookstores and from the American Medical Association at the following address:

UB-04 Revenue Codes
The Health First Colorado Revenue Code Table in Appendix Q, located on the Billing Manuals web page under the Appendices drop-down menu, contains revenue codes for billing services to Health First Colorado. Not all of the revenue codes listed are Health First Colorado benefits. When non-benefit revenue codes are used, the claim must be completed according to the billing instructions for non-covered charges. Claims submitted with revenue codes that are not listed are denied.
UB-04 Paper Claim Reference Table
The information in the following table provides instructions for completing form locators (FL) as they appear on the paper UB-04 claim form. Instructions for completing the UB-04 claim form are based on the current National Uniform Billing Committee (NUBC) UB-04 Reference Manual. Unless otherwise noted, all data form locators on the UB-04 have the same attributes (specifications) for the Health First Colorado as those indicated in the NUBCUB-04 Reference Manual.
All code values listed in the NUBC UB-04 Reference Manual for each form locator may not be used for submitting paper claims to the Health First Colorado. The appropriate code values listed in this manual must be used when billing the Health First Colorado.
The UB-04 Institutional Certification Form, located on the Provider Forms web page under the Claim Forms and Attachments drop-down menu, must be completed and attached to all claims submitted on the paper UB-04. Completed UB-04 paper Health First Colorado claims, including hardcopy Medicare claims, should be mailed to the correct fiscal agent address located in Appendix A, located on the Billing Manuals web page under the Appendices drop-down menu.
Each claim form has a set number of billing lines available for completion. Do not crowd more lines on the form. Billing lines in excess of the designated number are not processed or acknowledged. Claims with more than one page may be submitted through the Web Portal or batch.
