Mental health is primary care's business whether or not the practice is ready. This lesson covers the Collaborative Care Model and how it is paid for.
A large share of primary care visits involve mental health, and for many patients the primary care clinician is the only behavioral health provider they will ever see. Integrating behavioral health into primary care is therefore not an optional enhancement; it is meeting a demand that already exists.
Why integration, not referral
The traditional response is to refer out, and referral fails often: specialty capacity is scarce, waits are long, stigma deters patients, and a large fraction of referrals never result in a visit. Integration puts the capability where the patients already are, in the practice they already trust.
The Collaborative Care Model
The best-evidenced approach is the Collaborative Care Model (CoCM), which coordinates three roles:
- The primary care clinician, who continues to treat the patient and prescribes.
- A behavioral health care manager, who follows the patient closely, tracks symptoms with validated measures, and delivers or coordinates brief interventions.
- A psychiatric consultant, who reviews the caseload regularly and advises the team, rather than seeing every patient individually.
Worth remembering: the caseload-consultation design is what makes CoCM scalable. One psychiatric consultant reviewing a care manager’s caseload can support far more patients than one seeing patients one at a time, which is how a model can extend scarce psychiatric expertise across a whole primary care panel. Combined with measurement-based treat-to-target follow-up, this structure is why collaborative care has one of the stronger evidence bases in delivery redesign.
It is paid for
A practical point that removes a common objection: Medicare has paid for collaborative care since 2017 through dedicated Behavioral Health Integration codes, including the psychiatric collaborative care management codes (99492, 99493, 99494) and a general BHI code (99484). The treating clinician bills, while the care manager and psychiatric consultant do not bill separately for their CoCM work. Many commercial and Medicaid payers have followed.
That matters because it means integration does not depend solely on shared-savings upside; there is a fee-for-service payment pathway that can fund the staffing while the value accrues.
Key takeaways
- Behavioral health is already primary care’s work; referral out fails frequently, so integration meets the demand where patients are.
- The Collaborative Care Model pairs the primary care clinician with a behavioral health care manager and a caseload-reviewing psychiatric consultant, which is what makes scarce expertise scale.
- Medicare has paid for collaborative care since 2017 through dedicated BHI codes (99492-99494 and 99484), so there is a funding pathway beyond shared savings.

In the Collaborative Care Model, which three roles work together?
CoCM pairs the treating primary care clinician with a behavioral health care manager who follows the patient and a psychiatric consultant who reviews the caseload, which is what lets one psychiatrist support many more patients.
