Provider Qualifications

Providers must be enrolled as a Health First Colorado (Colorado's Medicaid Program) provider in order to:

  • Treat a Health First Colorado member
  • Submit claims for payment to Health First Colorado

Licensed physical therapists (PTs) and registered occupational therapists (OTs) who meet the qualifications prescribed by federal regulations for participation at 42 CFR 484.4 and who meet all the requirements under state law are eligible to become Colorado Medical Assistance providers.

Physical therapists must be licensed by the Colorado Department of Regulatory Agencies (DORA) pursuant to Title 12 Article 41.106 and may supervise up to four individuals at one time who are not physical therapists, including certified nurse aides, to assist in the therapist's clinical practice. Supervision authority extends to the limits stated in the Physical Therapists Practice Act per section C.R.S. § 12-41-113(1).

Physical therapist assistants (PTA) must be certified by DORA pursuant to Title 12 Article and must work under the supervision of a licensed physical therapist as defined in the Colorado Physical Therapy Practice Act (§ 12-41-203(2) C.R.S.) and accompanying rules as promulgated by the State Board of Physical Therapy.

  • PTAs cannot enroll with Health First Colorado and cannot place any identifying number on a claim form. Therefore, the supervising therapist's NPI number must be used as the rendering provider number on the claim form for services rendered by the assistant. Medical records must still indicate the assistant performed the services.

Occupational therapists must be registered by DORA pursuant to Title 12 Article 40.5.

Occupational therapy assistants (OTA) must practice under the general supervision of a Colorado registered occupational therapist.

  • OTAs cannot enroll with Health First Colorado and cannot place any identifying number on a claim form. Therefore, the supervising therapist's NPI number must be used as the rendering provider number on the claim form for services rendered by the assistant. Medical records must still indicate the assistant performed the services.

Therapy may also be rendered by licensed and enrolled physicians, physician assistants, and advanced practice nurses as allowed by their respective scopes of practice.

All providers must submit a completed provider enrollment to become a Health First Colorado provider. Visit the Provider Enrollment web page and the Revalidation web page for enrollment information.

General Benefit Policies

Physical and occupational therapists not employed by an agency, clinic, hospital, or physician may bill Health First Colorado directly, otherwise it is the employer who bills directly for the services. Providers should refer to the Code of Colorado Regulations, Qualified Non-Physician Practitioners Eligible to Provide Physician's Services (10 CCR 2505-10, Section 8.200.2.C), for further regulatory information when providing physical and occupational therapy.

  1. All PT/OT services must have a written order, referral, or prescription by any of the following:
    1. Physician (M.D. or D.O.)
    2. Physician's assistant
    3. Nurse practitioner
    4. An approved Individualized Family Service Plan (IFSP) for Early Intervention PT/OT
  2. Pursuant to the Affordable Care Act's requirements that State Medicaid Agencies ensure correct ordering, prescribing, and referring (OPR) National Provider Identification (NPI) numbers be on the claim form (42 CFR § 455.440):
    1. All Outpatient PT/OT claims must contain the valid NPI number of the OPR physician, physician assistant, nurse practitioner, or provider associated with an Individualized Family Service Plan (IFSP), in accordance with Program Rule 8.125.8.A.
      1. Community Centered Boards may have their NPI listed as the referring NPI for IFSP-ordered early intervention services.
    2. All physicians, physician assistants, nurse practitioners, or providers associated with an IFSP who order, prescribe, or refer Outpatient PT/OT services for Medicaid members must be enrolled in Health First Colorado (42 CFR § 455.410), in accordance with Program Rule 8.125.7.D. OPR Providers can begin enrollment on Health First Colorado's website.
      1. The new enrollment requirement for OPR providers does not include a requirement to see Medicaid members or to be listed as a Medicaid provider for patient assignments or referrals.
      2. Physicians or other eligible professionals who are already enrolled in Health First Colorado as participating providers and who submit claims to Health First Colorado are not required to enroll separately as OPR providers.
    3. Field 17.b on the CMS1500 claim form must be used for the OPR NPI number.
  3. The term "valid OPR NPI number" means the registered NPI number of the provider that legitimately orders, prescribes, or refers the Outpatient PT/OT service being rendered, as indicated by the procedure code on the claim.
    1. Claims without a valid OPR NPI number which are paid will then be subject to recovery.
    2. Medical documentation must be kept on file to substantiate the order, prescription, or referral for Outpatient PT/OT. Claims lacking such documentation on file will be subject to recovery.
  4. Health First Colorado recognizes that Outpatient PT/OT ordered in conjunction with an approved IFSP for Early Intervention may not necessarily have an ordering provider. Under this circumstance alone the rendering provider must use their own NPI number as the OPR NPI number.
    1. Early Intervention Outpatient PT/OT claims must have modifier 'TL' attached on the procedure line item for Health First Colorado to identify that the services rendered were associated with an approved IFSP.
      1. Any claim with modifier 'TL' attached must be for a service ordered by an approved IFSP.
      2. If the OPR NPI on the claim is that of the rendering provider, and the claim does not have modifier 'TL' attached, the claim is subject to recovery.
  5. Therapies provided as part of a member's individualized education program (IEP) by a therapist in the school setting are not separately reimbursable. These services are paid for by the school district which is reimbursed by the Department. Providers may not submit claims for services performed in the school setting. Refer to the School Health Services Program web page for details.

Early and Periodic Screening, Diagnostic and Treatment (EPSDT)

8.280.4.E Other EPSDT Benefits

Other health care services may include other EPSDT benefits if the need for such services is identified. The services are a benefit when they meet the following requirements:

  1. All goods and services described in Section 1905(a) of the Social Security Act are a covered benefit under EPSDT when medically necessary as defined at 10 C.C.R. 2505-10, Section, regardless of whether such goods and services are covered under the Colorado Medicaid State Plan.
  2. For the purposes of EPSDT, medical necessity includes a good or service that will, or is reasonably expected to, assist the client to achieve or maintain maximum functional capacity in performing one or more Activities of Daily Living; and meets the criteria set forth at Section - g.
  3. The service provides a safe environment or situation for the child.
  4. The service is not for the convenience of the caregiver.
  5. The service is medically necessary.
  6. The service is not experimental or investigational and is generally accepted by the medical community for the purpose stated.
  7. The service is the least costly.

Back to Top


Payment for Covered Services

  1. If Prior Authorization Requests (PAR) for services are required, the following policy applies:
    • Technical/lack of information (LOI) denial does not mean those services are not covered. Members may not be billed for services denied for LOI.
    • Services partially approved are still considered covered services. Members may not be billed for the denied portion of the request.
    • Services totally denied for not meeting medical necessity criteria are considered non-covered services.
  2. Members who reach the initial 48-unit limit for physical and occupational therapy (PT/OT) require a PAR to obtain further coverage. Refusal, failure, or negligence by the provider to request a PAR for services beyond the first 48 units of PT/OT does not mean that those additional services are non-covered.

Medically Necessary

Outpatient physical and occupational therapy services must be medically necessary to qualify for Health First Colorado reimbursement. Medical necessity (10 CCR 2505-10 means a Medical Assistance program good or service:

  1. Will, or is reasonably expected to prevent, diagnose, cure, correct, reduce, or ameliorate the pain and suffering, or the physical, mental, cognitive, or developmental effects of an illness, condition, injury, or disability.

Documentation Requirements

Rendering providers must document all evaluations, re-evaluations, services provided, member progress, attendance records, and discharge plans. All documentation must be kept in the member's records along with a copy of the referral or prescribing provider's order. Documentation must support both the medical necessity of services and the need for the level of skill provided. Rendering providers must copy the member's primary care provider (PCP), prescribing provider and/or medical home on all relevant records.

All documentation must include the following:

  1. The member's name and date of birth.
  2. The date and type of service provided to the member.
  3. The name or names and titles of the persons providing each service including assistants and the name and title of the therapist supervising or directing the services.

Health First Colorado requires the following types of documentation as a record of services provided within an episode of care: initial evaluation, re-evaluation, visit/encounter notes and a discharge summary.

Back to Top

Written documentation of the initial evaluation must include the following:

  1. Referral Information: Reason for referral and referral source.
  2. History: Must include diagnoses pertinent to the reason for referral, including date of onset, cognitive, emotional, and/or physical loss necessitating referral, and the date of onset, if different from the onset of the relevant diagnoses, current functional limitation or disability as a result of the above loss, and the onset of the disability, pre-morbid functional status, including any pre-existing loss or disabilities, review of available test results, review of previous therapies/interventions for the presenting diagnoses, and the functional changes (or lack thereof) as a result of previous therapies or interventions.
  3. Assessment: The assessment section must include a summary of the member's impairments, functional limitations and disabilities, based on a synthesis of all data/findings gathered from the evaluation procedures. Pertinent factors which influence the treatment diagnosis and prognosis must be highlighted, and the inter-relationship between the diagnoses and disabilities for which the referral was made must be discussed.
  4. Plan of Care: A detailed Plan of Care must be included in the documentation of an initial evaluation. This care plan must include the following:
    1. Specific treatment goals for the entire episode of care which are functionally-based and objectively measured
    2. Proposed interventions/treatments to be provided during the episode of care
    3. Proposed duration and frequency of services to be provided
    4. Estimated duration of episode of care.
  • An episode of outpatient therapy is defined as the period of time from the first day the member is under the care of the clinician for the current condition(s) being treated by one therapy discipline until the last date of service for that plan of care for that discipline in that setting.
  • The therapist's plan of care must be reviewed, revised if necessary, and signed, as medically necessary by the member's physician, or other licensed practitioner of the healing arts within the practitioner's scope of practice under state law at least once every 90 days.
  • The care plan may not cover more than a 90-day period, or the time frame documented in the approved IFSP.
  • A plan of care must be certified. Certification is the physician's, physician's assistant or nurse practitioner's approval of the plan of care. Certification requires a dated signature on the plan of care or some other document that indicates approval of the plan of care. If the service is a Medicare-covered service and is provided to a member who is eligible for Medicare, the plan of care must be reviewed at the intervals required by Medicare.

Back to Top



A re-evaluation must occur whenever there is an unanticipated change in the member's status, a failure to respond to interventions as expected or there is a need for a new plan of care based on new problems and goals requiring significant modification of treatment plan. The documentation for a re-evaluation need not be as comprehensive as the initial evaluation, but must include at least the following:

  1. Reason for re-evaluation
  2. Member's health and functional status reflecting any changes
  3. Findings from any repeated or new examination elements
  4. Changes to plan of care

Back to Top


Visit/Encounter Notes

Written documentation of each encounter must be in the member's record of service. These visit notes document the implementation of the plan of care established by the therapist at the initial evaluation. Each visit note must include the following:

  1. The member's name and date of birth.
  2. The date of service.
  3. The type of service provided to the member.
  4. Total timed code treatment minutes and total treatment time in minutes.
    1. Total treatment time includes the minutes for timed code treatment and untimed code treatment.
    2. Total treatment time does not include time for services that are not billable (e.g., rest periods).
    3. The time spent providing each service. The number of units billed/requested must match the documentation (billing and the total timed code treatment minutes must be consistent).
  5. A description of each service provided during the encounter including procedure codes. The description should support each procedure code billed.
  6. The name or names and titles of the persons providing each service including assistants and the name and title of the therapist supervising or directing the services.
  7. Identification of the short or long-term goals being addressed during the encounter.

In addition to the above required information items, the visit note documentation must contain the Subjective, Objective, Assessment and Plan format elements. These may be documented in any order (i.e., SOAP, APSO, etc.)

  1. A subjective element which includes the reason for the visit, the member/caregiver's report of current status relative to treatment goals, and any changes in member's status since the last visit,
  2. An objective element which includes the practitioner's findings, including abnormal and pertinent normal findings from any procedures or tests performed,
  3. An assessment component which includes the practitioner's assessment of the member's response to interventions provided, specific progress made toward treatment goals, and any factors affecting the intervention or progression of goals, and
  4. A plan component that states the plan for the next visit(s).

Non-Covered Services

  1. A member may receive outpatient physical therapy and occupational therapy services during the same period and service dates, however, duplicate therapy (the same therapy performed by both an OT and PT) may not be performed on the same dates of service. Duplicated services (in general, and those overlapped between PTs and OTs) are not covered.
  2. Art and craft activities for the purposes of recreation are not covered.
  3. Hippotherapy/equine therapy is not covered.

Rehabilitative and Habilitative Therapy Definitions

Health First Colorado covers both rehabilitative and habilitative therapies for all age groups in accordance with the Affordable Care Act Essential Health Benefit provisions.

The Colorado Division of Insurance defined Habilitative services to be:

Services that help a person retain, learn, or improve skills and functioning for daily living that are offered in parity with, and in addition to, any rehabilitative services offered in Colorado's Essential Health Benefits benchmark plan. Parity in this context means of like type and substantially equivalent in scope, amount, and duration.

Rehabilitative therapies are those meant to assist a member with recovery from an acute injury, illness, or surgical recovery. Habilitative therapies are those meant to help the member retain, learn, or improve skills and functions for daily living. This includes the treatment of long-term chronic conditions and meeting developmental milestones.

Back to Top


Additional Notes

  • Habilitative therapies are not categorized as an Inpatient or Home Health benefit. 'Acute' and 'Long-term' therapies remain benefits per Home Health coverage.
  • Habilitative therapies are not a benefit if provided in nursing facilities, Rehabilitative PT/OT remain benefits in that setting.
  • Habilitative therapies should not be confused with Habilitation services found within Home and Community Based Services (HCBS) waivers

Assistive Technology Assessments

The following billing policies are effective for CPT procedure code 97755 to accommodate HB14- 1211. HB14-1211 requires that all Medicaid members seeking complex rehabilitation technology must have an initial Assistive Technology Assessment (complex rehabilitative technology evaluation/assessment) prior to receiving complex rehabilitation technology, and follow-up assessments, as needed. Only licensed speech, physical, and occupational therapists may render this specialty evaluation. All providers using procedure code 97755 must follow these guidelines. The Department recognizes that only a portion of Assistive Technology Assessments will be used for complex rehabilitation technology evaluation/assessment. Providers will be asked upon PAR submission if the service is for a complex rehabilitation technology assessment.

Complex rehabilitation technology evaluations / assessments are billed using only 97755.Combinations of procedure codes, including procedure code 97542, for the purposes of complex rehabilitation technology evaluation / assessment are not allowed.
97755 always requires a Prior Authorization Request (PAR).PARs must be submitted electronically using ColoradoPAR. Visit the ColoradoPAR web page for details.
Member daily limit of 97755 is 20 units.Up to five hours of assessment is allowed per date of service.
Member yearly limit of 97755 is 60 units.Members may have up to 60 units of procedure code 97755 per State Fiscal Year (July 1 - June 30). This limit will reset with the start of each new State Fiscal Year.

PARs for 97755 must comply with the following policies:

  1. Must have a current prescription/referral for an Assistive Technology Assessment from the member's primary care physician.
  2. May indicate up to one-year duration.
  3. May indicate initial/new assessments or follow-up assessment visits.
  4. Only one active PAR for 97755 is allowed per member, per span of time. Overlapping 97755 PAR requests will be denied.
  5. Initial PT/OT evaluation services, such as 97161, are not required prior to requesting 97755.
  6. 97755 is separate from PT/OT and is not part of the PT/OT benefit limitation.
  7. PARs for 97755 should be submitted independently from other services. The Medical PAR type should be selected for 97755.

If a member requires further assessment by a different provider not indicated on the original PAR, and that PAR is still active, then it must be closed by the original requesting provider. Once closed a new PAR can be submitted. Members may request a 'change of provider' on their PAR by contacting the vendor directly. Refer to the Prior Authorization Request (PARs) section of this manual.

Back to Top


Benefit Limitations

  1. A daily limit of five units of physical therapy services and five units of occupational therapy services is allowed, whether it is rehabilitative or habilitative. Some specific daily limits per procedure code apply.
    1. Providers are required to consult the American Medical Association's (AMA) Current Procedural Terminology (CPT) manual for each coded service. Some codes represent a treatment session without regard to its length of time (one unit maximum) while other codes may be billed incrementally as "timed" units.
  2. Members may receive up to 48 units of any combination of PT/OT services per rolling 12-month period before a Prior Authorization Request (PAR) is required. Evaluation and orthotic services are not included in this limit. This equates to roughly 12 hours of therapy services (each unit of service being equal to 15 minutes). This unit limit will be automatically enforced by the claims payment system by denying claims that exceed the limit.
  3. Units of service exceeding the initial 48 units are not covered without an approved PAR.
  4. The 12-month period begins when therapy is initiated. The unit limit does not roll-over to accumulate more than 48 available units in a 12-month period. Units are continually available until the limit of 48 has been reached in a 12-month period.
  5. Units decrement from paid units for a specific member, regardless of provider, beginning on the first date of service. A unit equals either 1) a timed increment or 2) one treatment session as described in the specific CPT procedure codes.

Back to Top

Co-Treatment Policy

Co-treatment sessions between two outpatient therapists (pediatric behavioral therapists, physical therapists, occupational therapists, and/or speech-language pathologists) are a covered service under the following conditions:

  1. Valid clinical rationale for providing co-treatment must be present. Providers should refer to the Joint Guidelines for Therapy Co-Treatment developed by the American Speech-Language-Hearing Association (ASHA), American Occupational Therapy Association (AOTA), and American Physical Therapy Association (APTA).
  2. Each provider must have an approved Plan of Care (or IFSP for Early Intervention) which includes co-treatment. 
  3. Each provider must have an approved Prior Authorization which includes the Plan of Care/IFSP documentation that co-treatment will be used. 
  4. Each provider may only bill for the time they directly treat the member during the co-treatment session. Direct treatment means a one-on-one treatment interaction between the provider and the member and does not include observation. The intent of the Department is to not reimburse twice for the same increments of time the member receives treatment. Direct treatment times are not required to be contiguous spans of time and may be broken-up as the therapists alternate interacting with the member. The providers must then only bill for the total amount of time they individually spent providing direct treatment. 


A child receives one hour of co-treatment involving a Pediatric Behavioral Therapist and a Speech Therapist. While both providers are with the child for the full hour, during that time the Speech Therapist provides direct treatment for 30 minutes and the Pediatric Behavioral Therapist provides direct treatment for 30 minutes.

The Speech Therapist would report one unit of Current Procedural Terminology (CPT) 92507, because CPT 92507 is a visit-based unit regardless of time. The Pediatric Behavioral Therapist would report two units of CPT 97153, because CPT 97153 is billed in increments of 15 minutes.

A. Timed and Untimed Codes

When reporting service units for CPT/HCPCS codes where the procedure is not defined by a specific timeframe ("untimed" CPT/HCPCS), the provider enters "1" in the field labeled "units." For untimed codes, units are reported based on the number of times the procedure is performed, as described in the CPT/HCPCS code definition.

Example: A member received a speech-language pathology evaluation represented by HCPCS "untimed" code 92521. Regardless of the number of minutes spent providing this service, only one unit of service is appropriately billed on the same day.

Several CPT codes used for therapy modalities, procedures, tests and measurements specify that the direct (one-on-one) time spent in patient contact is 15 minutes. Providers report these "timed" procedure codes for services delivered on any single calendar day using CPT codes and the appropriate number of 15-minute units of service.

Example: A member received a total of 60 minutes of occupational therapy, e.g., HCPCS "timed" code 97530 which is defined in 15-minute units, on a given date of service. The provider would then report 4 units of code 97530.

B. Counting Minutes for Timed Codes in 15-Minute Units

When only one service is provided in a day, providers should not bill for services performed for less than 8 minutes. For any single timed CPT code in the same day measured in 15-minute units, providers bill a single 15-minute unit for treatment greater than or equal to 8 minutes through and including 22 minutes. If the duration of a single modality or procedure in a day is greater than or equal to 23 minutes, through and including 37 minutes, then 2 units should be billed. Time intervals for 1 through 8 units are as follows:

Back to Top


Units Number of Minutes

1 unit:• 8 minutes through 22 minutes
2 units:• 23 minutes through 37 minutes
3 units:• 38 minutes through 52 minutes
4 units:• 53 minutes through 67 minutes
5 units:• 68 minutes through 82 minutes
6 units:• 83 minutes through 97 minutes
7 units:• 98 minutes through 112 minutes
8 units:• 113 minutes through 127 minutes


The pattern remains the same for treatment times in excess of 2 hours.

When more than one service represented by 15-minute timed codes is performed in a single day, the total number of minutes of service (as noted on the chart above) determines the number of timed units billed. Refer to Example 1 below.

If any 15-minute timed service that is performed for 7 minutes or less than 7 minutes on the same day as another 15-minute timed service that was also performed for 7 minutes or less and the total time of the two is 8 minutes or greater than 8 minutes, then bill one unit for the service performed for the most minutes. This is correct because the total time is greater than the minimum time for one unit. The same logic is applied when three or more different services are provided for 7 minutes or less than 7 minutes. Refer to Example 5 below.

This Physical and Occupational Billing Manual and the Documentation Requirements section in the Speech Therapy Billing Manual indicates that the amount of time for each specific intervention/modality provided to the member is required to be documented in the Visits/Encounter Note. The total number of timed minutes must be documented. These examples indicate how to count the appropriate number of units for the total therapy minutes provided.

Example 1 -

24 minutes of neuromuscular reeducation, code 97112,
23 minutes of therapeutic exercise, code 97110,
Total timed code treatment time was 47 minutes.


Refer to the chart above. The 47 minutes falls within the range for 3 units = 38 to 52 minutes.

Appropriate billing for 47 minutes is only 3 timed units. Each of the codes is performed for more than 15 minutes, so each shall be billed for at least 1 unit. The correct coding is 2 units of code 97112 and one unit of code 97110, assigning more timed units to the service that took the most time.

Example 2 -

20 minutes of neuromuscular reeducation (97112)
20 minutes therapeutic exercise (97110),
40 Total timed code minutes.


Appropriate billing for 40 minutes is 3 units. Each service was done at least 15 minutes and should be billed for at least one unit, but the total allows 3 units. Since the time for each service is the same, choose either code for 2 units and bill the other for 1 unit. Do not bill 3 units for either one of the codes.

Example 3 -

33 minutes of therapeutic exercise (97110),
7 minutes of manual therapy (97140),
40 Total timed minutes


Appropriate billing for 40 minutes is for 3 units. Bill 2 units of 97110 and 1 unit of 97140. Count the first 30 minutes of 97110 as two full units. Compare the remaining time for 97110 (33-30 = 3 minutes) to the time spent on 97140 (7 minutes) and bill the larger, which is 97140.

Example 4 -

18 minutes of therapeutic exercise (97110),
13 minutes of manual therapy (97140),
10 minutes of gait training (97116),
8 minutes of ultrasound (97035),
49 Total timed minutes


Appropriate billing is for 3 units. Bill the procedures you spent the most time providing. Bill 1 unit each of 97110, 97116, and 97140. You are unable to bill for the ultrasound because the total time of timed units that can be billed is constrained by the total timed code treatment minutes (i.e., you may not bill 4 units for less than 53 minutes regardless of how many services were performed). You would still document the ultrasound in the treatment notes.

Example 5 -

7 minutes of neuromuscular reeducation (97112)
7 minutes therapeutic exercise (97110)
7 minutes manual therapy (97140)
21 Total timed minutes


Appropriate billing is for one unit. The qualified professional shall select one appropriate CPT code (97112, 97110, 97140) to bill since each unit was performed for the same amount of time and only one unit is allowed.

Note: The above schedule of times is intended to provide assistance in rounding time into 15-minute increments. It does not imply that any minute until the eighth should be excluded from the total count. The total minutes of active treatment counted for all 15-minute timed codes includes all direct treatment time for the timed codes. Total treatment minutes - including minutes spent providing services represented by untimed codes - are also documented.

Back to Top


C. Determining What Time Counts Towards 15-Minute Timed Codes

Providers report the code for the time actually spent in the delivery of the modality requiring constant attendance and therapy services. Pre- and post-delivery services are not to be counted in determining the treatment service time. In other words, the time counted as "intra-service care" begins when the therapist or physician (or an assistant under the supervision of a physician or therapist) is directly working with the patient to deliver treatment services. The patient should already be in the treatment area (e.g., on the treatment table or mat or in the gym) and prepared to begin treatment.

The time counted is the time the patient is treated. For example, if gait training in a patient with a recent stroke requires both a therapist and an assistant, or even two therapists, to manage in the parallel bars, each 15 minutes the patient is being treated can count as only one unit of code 97116. The time the patient spends not being treated because of the need for toileting or resting should not be billed. In addition, the time spent waiting to use a piece of equipment or for other treatment to begin is not considered treatment time.

Treatment time for untimed codes is not counted towards the total treatment time for 15-minute unit codes.

Prior Authorization Requests (PARs)

Providers must submit PARs for medically necessary services when services will exceed 48 units of service per 12-month period.

PARs are approved for up to a 12-month period (depending on medical necessity determined by the reviewer).

  • Retroactive PAR request forms will not be accepted.
  • Overlapping PAR request dates for same provider types will not be accepted, with the exception of Early Intervention PAR requests which may have overlapping dates of service and multiple provider types. All Early Intervention PT/OT PARs must additionally indicate that the member has an Individual Family Service Plan (IFSP) and that it is current and approved.
  • Only one PAR for Early Intervention outpatient PT/OT may be active at a time.
  • A maximum of one PAR for Early Intervention outpatient PT/OT and one PAR for non-Early Intervention outpatient PT/OT may be active at any time for children ages 0 - 4.
  • Overlapping Early Intervention and non-Early Intervention outpatient PT/OT PARs will only be accepted if the treatment plans associated with each meet different goals and use different treatments.
  • Incomplete, incorrect or insufficient member information on a PAR request form will not be accepted.
  • An approved Individualized Family Service Plan serves as medical necessity, an order/prescription, and a Plan of Care. 

Submit PARs for the number of units for each specific procedure code requested, not for the number of services. Modifier codes must be included. The same modifiers used on the PAR must be used on the claim, in the same order.

  • When submitting Rehabilitative Therapy PARs, and subsequent claims, CPT codes for PT services must have the GP modifier and the 97 modifier (e.g., 97110+GP+97). CPT codes for OT services must have the GO modifier and 97 modifier (e.g., 97110+GO+97).
  • When submitting Habilitative Therapy PARs, and subsequent claims, CPT codes for PT services must have the GP modifier and 96 modifier (e.g., 97110+GP+96). CPT codes for OT services must have the GO modifier and 96 modifier (e.g., 97110+GO+96).
  • Early Intervention PARs, and subsequent claims, must have the GP or GO modifier plus the TL modifier (e.g., 97110+GP+TL).

Additional Limitations:

  • Members may have one active PAR for each type of therapy (Rehabilitative PT, Rehabilitative OT, Habilitative PT, and Habilitative OT) with independent time spans. These PARs may not overlap in time span unless one of them is for Early Intervention.
  • Evaluation and orthotic services do not require a PAR.

PAR Requirements:

  • Legibly written and signed ordering practitioner prescription, approved Plan of Care, or approved Individualized Family Service Plan, to include:
    • diagnosis (preferably with ICD-10 code), and
    • reason for therapy, and
    • the number of requested therapy sessions per week, and
    • total duration of therapy.
  • The member's Physical or Occupational treatment history, including current assessment and treatment. Include duration of previous treatment and treating diagnosis.
  • Documentation indicating if the member has received PT or OT under the Home Health Program or inpatient hospital treatment.
  • Current treatment diagnosis.
  • Course of treatment, measurable goals and reasonable expectation of completed treatment.
  • Documentation supporting medical necessity for the course and duration of treatment being requested. This may include documentation of home exercise programs.
  • Assessment or progress notes submitted for documentation, must not be more than 60 days prior to submission of PAR request.
  • If the PAR is submitted for services delivered by an independent therapist, the name and address of the individual therapist providing the treatment must be present in field #24 of the PAR.
  • The billing provider name and address needs to be present in field #25 on the PAR.
  • The Health First Colorado provider number of the independent therapist must be present in PAR field #28.
  • The billing provider's Health First Colorado number must be present in field #29 of the PAR.
  • Early Intervention PT/OT PARs must additionally indicate that the member has an Individual Family Service Plan (IFSP) and that it is current and approved.
  • DME products cannot be requested on the same PAR as therapy services.

The authorizing agency reviews all completed PARs and approves or denies, by individual line item, each requested service or supply listed on the PAR. PAR status inquiries can be made through the Online Provider Web Portal and results are included in PAR letters sent to both the provider and the member. Read the results carefully as some line items may be approved and others denied. Do not render or bill for services until the PAR has been processed.

The claim must contain the PAR number for reimbursement. If the PAR is denied, providers should direct inquiries to the authorizing agency, which can be found on the Provider Contacts web page.
