The CY2024 G0511 transition: what RHCs and FQHCs actually need to do for care-management billing in 2026

CMS unbundled the single G0511 code into 5 categories of underlying CPT codes (CCM, BHI, PCM, RPM, RTM). Reimbursement is roughly equivalent; the workflow changed meaningfully. Here's the practical migration playbook.

Frequently asked questions

What changed for RHC and FQHC care-management billing in CY2024?

CMS' CY2024 Physician Fee Schedule Final Rule (published November 2023) began transitioning RHCs and FQHCs from billing the single bundled G0511 code to billing the underlying individual CPT codes for each care-management service: CCM (99490, 99491, 99437, 99439), BHI (99492-99494), Principal Care Management (99424-99427), RPM (99453-99458), RTM (98980-98981), and others. Total reimbursement is roughly equivalent — CMS designed the transition to be revenue-neutral — but the billing workflow changed meaningfully: each service now requires its own CPT line, its own documentation requirements, and (in some cases) its own consent.

When does the G0511 transition actually take effect?

CMS finalized the transition in the CY2024 PFS Final Rule. The transition was structured as a phased implementation through CY2025: G0511 remained billable through 2024 as MACs operationalized acceptance of the underlying CPT codes. By CY2025, most RHCs and FQHCs were expected to have migrated to the underlying CPT structure. As of 2026, MAC-by-MAC variation persists — some MACs still accept G0511 as a transition mechanism for legacy claims, while others require the underlying CPT codes for all new claims. Confirm with your specific MAC before changing your billing workflow.

Does the transition increase or decrease total reimbursement?

Roughly equivalent — CMS designed the transition to be revenue-neutral on average. In some scenarios the underlying-CPT model pays more (when a patient is enrolled in multiple care-management services that previously bundled under a single G0511); in other scenarios it pays similarly. The bigger operational question is workflow overhead: the underlying-CPT model requires more discrete documentation per service, while G0511 was a single monthly attestation. For most RHCs the net is a small increase in billing complexity for revenue-equivalent payment.

What are the underlying CPT codes I now need to bill?

Five categories: (1) CCM — Chronic Care Management: 99490 (initial 20 min/month), 99491 (provider-personally-performed 30 min/month), 99437 (additional 30 min for 99491), 99439 (additional 20 min for 99490). (2) BHI — Behavioral Health Integration: 99492 (initial 70 min in first month), 99493 (subsequent months 60 min), 99494 (additional 30 min). (3) PCM — Principal Care Management: 99424 (provider-personally-performed initial 30 min), 99425 (additional 30 min), 99426 (clinical-staff-performed initial 30 min), 99427 (additional 30 min). (4) RPM — Remote Physiologic Monitoring: 99453 (device setup), 99454 (device supply, 30-day), 99457 (initial 20 min/month treatment management), 99458 (additional 20 min). (5) RTM — Remote Therapeutic Monitoring: 98980 (initial 20 min/month treatment management), 98981 (additional 20 min).

Can I still bill G0511 in 2026?

MAC-dependent. Some MACs continue to accept G0511 for transition purposes, particularly for legacy claims and for clinics that haven't yet migrated workflows. Other MACs have already shifted to requiring the underlying CPT codes for all new claims. The CMS final rule envisioned G0511 sunsetting over the CY2024-2025 transition period, but operational reality varies. Practical recommendation: ask your MAC directly whether they currently accept G0511 for the relevant clinical service categories, and what their target sunset date is.

Do the documentation requirements change?

Yes — each underlying CPT has its own documentation requirements. CCM (99490) requires consent, comprehensive care plan, and ≥20 minutes of clinical-staff time per calendar month. BHI (99492-99494) additionally requires a behavioral-health care manager and consultation with a psychiatric consultant. RPM (99453-99458) requires the patient to use an FDA-defined medical device that transmits data, with ≥16 days of readings in a 30-day period for 99454. The shift from G0511's single monthly attestation to per-service documentation is the biggest operational change.

Can the same patient be billed for multiple care-management services in the same month?

Yes, with some constraints. CCM + BHI cannot both be billed for the same patient in the same month — they're considered overlapping. CCM + RPM CAN both be billed for the same patient in the same month, as can CCM + PCM (different chronic conditions for each). RPM + RTM CANNOT be billed for the same patient in the same month — they're mutually exclusive. The general rule: review the CMS-published code-pairing edits before assuming a combination is billable.

What's the per-patient revenue under the new model?

Approximate Medicare allowed amounts (CY2026 national, before geographic adjustment): CCM 99490 ~$62/month + 99439 add-on ~$47 per additional 20 min; BHI 99492 ~$165 (initial month) + 99493 ~$130 (subsequent months); PCM 99426 ~$60/month + 99427 ~$50 add-on; RPM 99454 ~$43/month device supply + 99457 ~$50/month treatment management; RTM 98980 ~$50/month + 98981 ~$40 add-on. A patient enrolled in CCM + RPM + RTM (where applicable) could generate $135-$200/month vs ~$68/month under old G0511 — but only if the patient genuinely qualifies for each service and the documentation supports it.

What's the most common error when migrating from G0511?

Trying to bill all unbundled codes for every G0511 patient. The codes have specific eligibility criteria (chronic conditions for CCM, behavioral-health diagnosis + collaborative-care arrangement for BHI, physiologic-data device for RPM). A patient previously billed G0511 because they had ≥2 chronic conditions and were getting general care management does NOT automatically qualify for all of CCM + BHI + RPM. Audit your panel and bill only the services actually being delivered with documentation that supports each.

Where do I find the canonical CMS guidance?

CY2024 PFS Final Rule (CMS-1784-F, published November 16, 2023, Federal Register) is the foundational document. CMS MLN Booklet "Care Management Services" (MLN908628, updated 2024) has the practical billing reference. The CMS Manual System Pub. 100-04, Chapter 9 covers RHC/FQHC-specific guidance. Your MAC also publishes operational instructions specific to its jurisdiction — those override generic CMS guidance for billing purposes.

How does Triad Rev help with the G0511 transition?

Triad Rev pulls your Medicare PUF and your active patient panel, identifies which patients qualify for which underlying codes (CCM, BHI, PCM, RPM, RTM), generates the documentation templates required for each, and tracks monthly billing capture rates by code. End-of-month attestation is one click instead of a 4-hour reconciliation. $499/mo, 90-day free pilot.
