What's inside
What the model is
In the Collaborative Care Model, a primary care team treats behavioral health conditions with the support of a behavioral health care manager and a psychiatric consultant, tracked in a registry with measurement-based care. The IMPACT trial is the evidence base most often cited.
The CoCM codes, by number
- 99492: initial psychiatric collaborative care management, first calendar month
- 99493: subsequent psychiatric collaborative care management, later months
- 99494: add-on for additional time in a month, used with 99492 or 99493
- G2214: initial or subsequent CoCM for a shorter block of time in a month
General behavioral health integration
99484 covers general behavioral health integration care management that does not use the full collaborative care structure.
Who bills and what to confirm
- The treating primary care practice typically bills these codes; the psychiatric consultant is paid by the practice
- Time is tracked per calendar month
- Confirm the current time thresholds, consent rules, and payer coverage before billing
