Medicaid in Colorado and Tennessee Now Covers Collaborative Care
As of July 1, 2025, both Colorado and Tennessee will now reimburse primary care providers for delivering mental health services through the Collaborative Care Model (CoCM). With these updates, Colorado and Tennessee join 34 other states in covering Collaborative Care through Medicaid.
Though CoCM is one of the most evidence-backed ways to increase access to mental health care, Medicaid reimbursement has remained a barrier to expanding implementation throughout the United States.
COLORADO
Colorado’s Medicaid program (Health First Colorado) officially added Collaborative Care billing codes on July 1 as part of its Integrated Care Sustainability Policy. Providers can now bill for services using CPT codes 99484, 99492, 99493, 99494, and G-codes G0323 and G2214.
Participating practices must:
- Contract with a Regional Accountable Entity (RAE) or Managed Care Organization (MCO)
- Employ or contract with a behavioral health care manager and a psychiatric consultant
- Engage in weekly case reviews between care managers and psychiatric consultants
This is a big step toward expanding access to behavioral health services across the state.
TENNESSEE
Tennessee’s Medicaid program (TennCare) also added Collaborative Care billing codes on July 1 as part of its semiannual policy update. These changes enable providers to bill for services that support longer-term, team-based mental health care, rather than just one-off visits. With reimbursement now possible, more primary care practices can afford to hire care managers and work alongside consulting psychiatrists to provide whole-person care.
