Outpatient Behavioral Health Fee-for-Service

Return to Billing Manuals Web Page


General Policies

  • Health First Colorado (Colorado's Medicaid program) members have their behavioral health services paid for by Regional Accountable Entities (RAEs). Regional Accountable entities are managed care entities responsible for covering behavioral health benefits for nearly all Health First Colorado members.
  • Beginning July 2018 members have up to six (6) short-term behavioral health visits per fiscal year covered in the primary care setting, billed FFS to the fiscal agent Gainwell Technologies. Visit the Accountable Care Collaborative Phase Two web page for exact details on this policy.
  • See Program Rule 8.212 for details about the RAE program, including policy which exempts Health First Colorado members from RAE coverage. Only a small percentage of members meeting very specific criteria will be exempt. Member exemption is determined by the Department.
  • Visit the Department's Regional Accountable Entity web page for details about RAE coverage.
  • To verify if a Health First Colorado member's behavioral health services are covered by a RAE, providers must perform a member eligibility query in the Provider Web Portal. Each RAE may have its own similar tool for providers to query member eligibility. Both tools are valid for checking member eligibility.
  • The member eligibility query will display whether the RAE is responsible for covering the member's services. If the member is covered by the RAE, all claims for covered behavioral health services must be sent to the RAE for payment.
  • All behavioral health providers must be enrolled with the RAE. Providers must contact the RAE which serves their region to begin the enrollment process. Visit the Department's Regional Accountable Entity web page for details.
  • Providers who are denied RAE enrollment may not bill Gainwell Technologies fee-for-service (FFS) as an alternative reimbursement route. If the provider is denied RAE enrollment this means that may not treat Health First Colorado members for services covered by the RAE.
  • Providers who are denied RAE enrollment may still render and be reimbursed for services not covered by the RAE.
  • A number of services, such as office administered drugs (e.g. Suboxone) are covered Health First Colorado benefits but are not covered by the RAE. These services must always be billed to Gainwell Technologies FFS. Reference the coverage diagram below.
  • Providers must reference Appendix T located under the Appendices drop-down on the Billing Manuals web page for a list of RAE-covered services and conditions.

Special Provision: EPSDT Services Can Exceed Policy Limitations For Members Age 20 And Younger

Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) is a federal Health First Colorado) program that requires the state Health First Colorado agency to cover services, products, or procedures for Health First Colorado members ages 20 and younger if the service is medically necessary health care to correct or ameliorate a defect, physical or mental illness, or a condition (health problem) identified through a screening examination (includes any evaluation by a physician or other licensed clinician). EPSDT covers most of the medical or remedial care a child needs to improve or maintain his/her health in the best condition possible, compensate for a health problem, prevent it from worsening, or prevent the development of additional health problems.

EPSDT does not require the state Health First Colorado agency to provide any service, product, or procedure that is:

  • Unsafe, ineffective, or experimental/investigational.
  • Not medical in nature or not generally recognized as an accepted method of medical practice or treatment.

Service limitations on scope, amount, duration, frequency, and/or other specific criteria described in the above screening policies may be exceeded or may not apply as long as the provider documentation shows how the service, product, or procedure will correct, improve or maintain the recipient's health, compensate for a health problem, prevent it from worsening, or prevent the development of additional health problems.

Providers may be subject to post-payment review to assure the use of a validated, standardized screening tool and medical justification for screens in excess of the stated benefit limits.

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. Providers should refer to the monthly bulletins located on the Bulletins web page. To receive electronic provider bulletin notifications, an email address can be entered into the Provider Web Portal in the (MMIS) Provider Data Maintenance area or by filling out a publication preference form. Bulletins include updates on approved procedure codes as well as the maximum allowable units billed per procedure.
