Advanced Primary Care Management, explained. One monthly payment, no minute logs.

Key takeaways

• APCM is a flat monthly payment per patient for comprehensive primary care management. Medicare launched it on January 1, 2025. Unlike Chronic Care Management (CCM), it has no time-tracking requirement — you are paid for maintaining the care relationship, not for logging minutes.
• It is billed under Original Medicare fee-for-service, not Medicare Advantage — reported by the primary care practice at national Physician Fee Schedule rates, adjusted by your Medicare Administrative Contractor (MAC).
• Three payment levels, by patient complexity: G0556 (Level 1) about $16 per patient per month, G0557 (Level 2) about $54, and G0558 (Level 3) about $117 for Qualified Medicare Beneficiary (QMB) and dual-eligible patients. Level 2 is the center of gravity for most Medicare panels.
• APCM cannot be billed the same month as CCM, PCM, or TCM for the same patient — but it can be billed alongside RPM. New-for-2026 behavioral-health add-on codes (G0568, G0569, G0570) stack on the APCM base, up to roughly $263 per patient per month combined.
• The panel math is straightforward: a 200-patient Level-2 panel is $54 × 200 × 12 ≈ $129,600 per year in recurring Medicare revenue — before any RPM or behavioral-health stacking.
• CareAtlas offers APCM as a turnkey program. HealthQuilt drafts the required care plan and your physician signs it; the patient stays with their existing PCP of record; typical go-live is 60 days — and you don’t add staff.

This guide includes

Advanced Primary Care Management (APCM) is the newest way Medicare pays a primary care practice to manage a patient between visits — and it is structurally different from everything that came before it. Where CCM and its cousins pay per code for logged minutes of service, APCM pays a single flat amount per patient per month for keeping the care relationship whole: a current care plan, 24/7 access, coordination, and continuity. Medicare launched it on January 1, 2025, and refined it in the CY2026 Physician Fee Schedule.

This guide is written for the person deciding whether APCM belongs on their panel: the physician, the practice administrator, the billing lead at a primary care practice, community health center, FQHC, or RHC. It lays out the definition, the three payment levels, exactly who and what qualifies, the co-billing rules that trip practices up, the revenue math on a real panel, and how to run the program turnkey — so the coordination happens and the claim is clean without hiring against it.

What is APCM?

Advanced Primary Care Management (APCM) is Medicare’s flat, per-patient monthly payment for comprehensive primary care management, launched January 1, 2025. A practice enrolls an eligible patient once, maintains a defined set of primary-care management services for them, and bills a single monthly code — no minute counting, no per-service timers.

The design goal is to pay for the relationship, not the stopwatch. Traditional care-management codes (like CCM’s 99490 family) reimburse only when staff log enough qualifying minutes in a calendar month; a light-touch month can go unbilled even though the practice is still on the hook for the patient. APCM removes that logic. As long as the practice makes the required services available and the qualifying elements are in place, the monthly payment applies. That also lowers audit exposure — as AI-driven payer audits of time logs have intensified, industry-reported denial rates on time-based care-management claims have climbed into the 15–25% range, a risk the flat APCM model sidesteps.

Two boundaries matter from the start. First, APCM is billed under Original Medicare fee-for-service at national Physician Fee Schedule rates — it is not a Medicare Advantage benefit, and MA plans set their own care-management arrangements. Second, APCM is a primary care program: it is anchored to the clinician who serves as the patient’s continuing focal point for care, not to a specialty-only practice.

The three APCM levels

APCM pays across three levels, set by patient complexity, each with its own HCPCS code and national rate. The higher the coordination burden, the higher the monthly payment. Level 2 is where most Medicare panels concentrate.

Rates are 2026 national averages, rounded, and adjusted by your Medicare Administrative Contractor (MAC) and locality. Confirm your locality’s amounts before you model revenue.

Level 2 (G0557) is the center of gravity. Most Medicare beneficiaries carry two or more chronic conditions, so the bulk of a typical panel lands here at roughly $54 per patient per month. Level 3 (G0558) exists for the highest-need population — Qualified Medicare Beneficiaries and dual-eligible patients whose coordination burden runs heaviest — and pays about $117 per patient per month to reflect it.

Who and what qualifies

APCM requires a primary-care anchor, a physician-signed comprehensive care plan, one-time patient consent, 24/7 access with continuity, and general supervision — and it asks the practice to make a defined set of care-management services available. Here are the required elements, described in categories.

• A primary-care relationship. APCM is billed by the clinician (or practice) serving as the patient’s continuing focal point for primary care. Specialty-only groups do not qualify to bill APCM for a patient.
• An initial comprehensive care plan, physician-signed. Each enrolled patient needs a comprehensive, electronic care plan established, signed by the billing practitioner, and refreshed on a quarterly cadence.
• Patient consent, obtained once. Consent is captured a single time at enrollment (documenting cost-sharing and the right to stop), then carried forward — it does not repeat monthly.
• 24/7 access and continuity of care. The patient must have around-the-clock access to a care team member for urgent needs, and continuity with a designated practitioner or care team.
• General supervision. APCM services may be furnished under general supervision — the billing practitioner need not be physically present while clinical staff deliver the service.

Beyond those, CMS defines a broader set of roughly 13 APCM service elements the practice must make available — spanning comprehensive care management, the care plan itself, management of care transitions, coordination with home- and community-based services, enhanced (24/7 and asynchronous) communication, patient-population-level management, and performance measurement. Treat that count and its groupings as directional and confirm the current list on the CMS Advanced Primary Care Management page before you build to it; CMS has adjusted the elements between rule cycles.

RHCs and FQHCs are eligible to bill APCM. For community health centers rebuilding a care-management workflow — for example, after the G0511 bundle was retired — APCM’s no-time-tracking, general-supervision design tends to fit rural and safety-net staffing realities. See the companion guide, G0511 is gone: how RHCs & FQHCs bill care management now.

What you can — and can’t — bill alongside APCM

APCM cannot be billed in the same calendar month as CCM, PCM, or TCM for the same patient — but it can be billed alongside RPM, and the new 2026 behavioral-health add-ons stack on top of it. APCM already includes the comprehensive care-management work that CCM and PCM pay for separately, so Medicare does not let you bill both for the same patient in the same month.

The stacking on the paid side is real. APCM plus RPM plus the 2026 behavioral-health add-ons — G0568 (Collaborative Care Model initial month), G0569 (CoCM subsequent months), and G0570 (general Behavioral Health Integration) — can reach roughly $263 per patient per month combined for the highest-complexity patient who qualifies for all of it. Treat that ceiling as directional and locality-variable; it applies only where every element is clinically indicated and documented. The APCM + RPM revenue math has its own guide: APCM + RPM: the co-billing stack.

The panel math

A 200-patient Level-2 panel is about $129,600 per year in recurring Medicare revenue. The arithmetic is deliberately simple, which is the point of a flat monthly model:

$54 /patient/mo × 200 patients × 12 months ≈ $129,600 / year

That figure is Level 2 (G0557) alone — before any Level 3 patients at the higher $117 rate, before RPM stacked on eligible patients, and before the behavioral-health add-ons. It is also recurring: the payment applies every month the enrolled relationship is maintained, not per episode or per logged block of minutes. Model your own panel’s tier mix and enrollment ramp with the ROI calculator — the number moves with how your Level 1 / 2 / 3 patients distribute.

How CareAtlas delivers APCM

CareAtlas offers APCM as a turnkey program — HealthQuilt drafts the required care plan, your physician signs it, and the patient stays with their existing PCP of record. The codes are the easy part. The hard part is the operating model: enrolling the right patients, keeping every care plan current, running the monthly touches, and capturing each required element so the claim holds up. That is where a practice runs out of people, not intent.

CareAtlas runs that model as an extension of your practice. HealthQuilt, our platform, drafts each patient’s comprehensive care plan from the chart and the enrollment conversation; your physician reviews, edits where needed, and signs — the clinical judgment stays with the clinician. A dedicated, named care navigator — a real person, not a chatbot or an app — delivers the monthly outreach, averaging 4+ touches per patient per month, and routes clinical concerns back to the PCP. Every qualifying element is captured as the work happens, so what reaches billing is clean. Clinical services are delivered by CareAtlas’s affiliated professional corporation, with your physician as provider of record; CareAtlas operates the workflow, the platform, and the documentation around them.

The economics are structured to work: the CareAtlas fee is disclosed and sized below what Medicare reimburses, so the program is net margin positive by design — your practice keeps the difference. Typical go-live is 60 days from signature to your first enrolled patient.

A note on timing. CareAtlas is bringing APCM online now and offers it to partner practices; our first live APCM claim is expected in 2026. Published CareAtlas outcome figures (readmissions, device adherence) come from our RPM/CCM cohort, not from APCM.

Documentation & denials

With a flat monthly model, the audit exposure moves from minute logs to the care plan and the qualifying elements. APCM removes the timer, but it does not remove documentation — it relocates it. What a payer will look for is a comprehensive care plan that is present, signed, and current; consent captured once and carried forward; evidence the 24/7-access and continuity requirements are actually met; and the general-supervision relationship documented.

The defensible move is structured capture: the care plan versioned and quarterly-refreshed, consent logged and carried, and each required service element evidenced as it is delivered rather than reconstructed at claim time. CareAtlas’s platform captures those elements in the moment the work happens — which is the difference between a clean APCM claim and a denial that erases the margin the program was meant to create.
