Federally Qualified Health Centers and Rural Health Clinics bill collaborative care through a separate HCPCS "G-code" path rather than the standard CPT codes other practices use. Because FQHCs and RHCs are paid under encounter-based rates instead of the standard fee schedule, CMS created dedicated codes — historically G0512 for psychiatric Collaborative Care and G0511 for general care management — to reimburse this work. Confirm the current-year rule with CMS and your MAC.

The Collaborative Care Model (CoCM) is billed the same way clinically in every setting: a behavioral health care manager, the primary care provider, and a consulting psychiatrist track a caseload with validated tools and adjust treatment until symptoms improve. But *how* that work gets paid depends heavily on the type of practice. FQHCs and RHCs sit on a different payment track than a typical primary care office, and the billing mechanics follow.

Why do FQHCs and RHCs bill collaborative care differently?

Most primary care practices are paid under the Medicare Physician Fee Schedule (PFS), where each service has its own CPT code and rate. FQHCs and RHCs are not. They are paid under encounter-based systems — a Prospective Payment System (PPS) rate per visit for FQHCs, and an All-Inclusive Rate (AIR) per visit for RHCs. Those per-visit rates were designed around face-to-face encounters, not the month-long, between-visit care coordination that collaborative care depends on.

To make collaborative care reimbursable in these settings, CMS built a parallel path using HCPCS G-codes. The clinical model is identical; the billing wrapper is different. This is the single most important thing for an FQHC or RHC to understand: the standard CoCM CPT codes are generally not how you get paid — the G-codes are.

What is G0512, and how does it differ from the standard CPT codes?

In a standard PFS practice, monthly Collaborative Care is billed with a family of time-based CPT codes — commonly 99492 and 99493 (initial and subsequent months) plus 99494 (add-on for additional time), and 99484 for General Behavioral Health Integration (BHI) that doesn't use the full CoCM team structure.

FQHCs and RHCs have historically not billed those codes directly. Instead, CMS created:

• G0512 — a single, bundled code for psychiatric Collaborative Care furnished by an FQHC or RHC, meant to correspond to the CoCM CPT work (99492/99493/99494) rolled into one payment.
• G0511 — a general care management code that has covered General BHI (the 99484 equivalent) along with other chronic care management services in these settings.

The practical difference is bundling. Where a PFS practice might report several distinct CPT lines in a month, an FQHC or RHC historically reported one G-code that stood in for that bundle, paid at a rate CMS set by averaging the relevant national PFS amounts. That keeps the encounter-based payment logic intact while still recognizing the care management work.

Important caveat: CMS has revised this area repeatedly, including recent moves toward letting FQHCs and RHCs report the individual care management codes rather than a single bundled G-code, sometimes with transition periods. Treat the code numbers above as the established framework, not a guarantee of the current-year mechanics. Always confirm which codes are active, how they are valued, and any billing-frequency limits with current CMS guidance and your Medicare Administrative Contractor (MAC) before you submit.

What has to be true clinically before you can bill it?

The billing path doesn't change the model's requirements. To bill collaborative care — G-code or CPT — the same core elements generally must be in place:

• A treating primary care provider who initiates the service and remains responsible for the patient's care.
• A behavioral health care manager with a caseload, doing regular, often between-visit outreach and support.
• A psychiatric consultant who reviews the caseload — typically through a registry — and advises on treatment without necessarily seeing the patient directly.
• A validated, measurement-based approach — tracking symptoms with tools like the PHQ-9 and GAD-7 and changing the plan when scores don't improve.
• Patient consent, documented, including any cost-sharing implications.

If a practice is only doing informal "warm handoffs" without a care manager, a registry, and psychiatric caseload review, that is generally not billable CoCM — it may fall under General BHI at best, or under nothing at all.

What are the documentation basics?

Collaborative care is a time-based, team-based service, so documentation has to show both the time and the team. At minimum, plan to capture:

• Consent — obtained and recorded before the service starts, including the patient's agreement to any applicable cost-sharing.
• Time tracking — cumulative care-management minutes per calendar month, since the codes are built around monthly time thresholds. Log who did the work and what they did.
• The initial assessment and care plan — including a validated rating scale at baseline.
• Ongoing measurement — repeat PHQ-9/GAD-7 (or condition-appropriate) scores over time, showing the caseload is being actively managed.
• Registry and psychiatric consultation — evidence that the patient is tracked in a registry and that the psychiatric consultant reviewed the case and gave recommendations.

Because minutes accumulate across a calendar month, most FQHCs and RHCs need a registry or tracking system rather than trying to reconstruct time from visit notes. Good time capture is usually the difference between billable and unbillable months.

How should an FQHC or RHC get started?

Start by confirming the payment path, not the clinical model. Verify with your MAC exactly which codes your center should report this year, how they're valued under your PPS or AIR arrangement, and whether any recent CMS rule change has moved you toward individual codes. Then make sure the clinical infrastructure — care manager, registry, psychiatric consultant, consent workflow, and monthly time tracking — is in place before the first claim, since the documentation requirements are the same regardless of which code you land on.

Frequently asked questions

Can an FQHC or RHC bill the standard CoCM CPT codes (99492, 99493, 99494)?

Historically, no — FQHCs and RHCs have used the G-code path (such as G0512) rather than reporting those CPT codes directly, because they're paid under encounter-based rates instead of the standard fee schedule. CMS has revised this over time, so confirm the current-year rule with your MAC.

What's the difference between G0512 and G0511?

G0512 has been the code for psychiatric Collaborative Care (the full CoCM team model) in FQHCs and RHCs, while G0511 has covered general care management, including General BHI. The former maps to the CoCM CPT family; the latter to the 99484-type BHI work. Verify current definitions before billing.

Do the documentation requirements differ for an FQHC versus a regular practice?

The clinical documentation is essentially the same: consent, monthly time tracking, a validated baseline and follow-up measures, registry tracking, and psychiatric consultation. What differs is the billing code and how the service is valued under PPS or AIR, not what the care team must document.

Is patient consent required?

Yes. Collaborative care generally requires documented patient consent before the service begins, including acknowledgment of any cost-sharing. Record it in the chart.

Why do these rules keep changing?

CMS updates the Physician Fee Schedule and FQHC/RHC payment policies annually, and collaborative care and BHI have been areas of active change — including how bundled G-codes relate to individual codes. Treat any specific code or rate as a snapshot and confirm the current-year guidance.
