Three add-ons, reported with an APCM base code
Starting in 2026, CMS added behavioral health codes that a practice reports on top of an APCM base code (G0556, G0557, or G0558) when the same practitioner furnishes both in the month. Like APCM itself, they are not built around monthly time thresholds.
| Code | Service | Closest standalone code |
|---|---|---|
| G0568 | Psychiatric Collaborative Care Model, first month | 99492 |
| G0569 | Psychiatric Collaborative Care Model, subsequent months | 99493 |
| G0570 | General behavioral health integration | 99484 |

What the practice needs
An APCM patient
The patient is enrolled in APCM with the same billing practitioner for the month.
A behavioral health need
A mental, behavioral health, or substance use condition that the practitioner judges needs care management.
The service elements
Initial assessment, a care plan, ongoing monitoring with validated rating scales, and care coordination. CoCM also needs a behavioral health care manager and a psychiatric consultant.
Documentation
Scores, plan changes, consultant input, and follow-up, recorded against the month the add-on is billed.
Standalone BHI codes still exist
Practices not billing APCM for a patient can use the time-based codes: 99484 for general BHI, 99492 to 99494 for CoCM, and G2214. Do not report a standalone code and its APCM add-on for the same service in the same month.
Building BHI into monthly check-ins
- Screen. Add validated questions, such as PHQ-2 or GAD-2, to check-in scripts your clinicians approve.
- Escalate. Positive screens and any safety concern go straight to a named clinician. Crisis language follows a fixed emergency path.
- Track. Record rating-scale scores each month so change over time is visible.
- Review. The add-on appears as a candidate in the monthly evidence packet, and your team decides whether it is supported.
