Key Takeaways:
- Advanced Primary Care Management (APCM) is Medicare's newest care management program, launched January 1, 2025, with 2026 reimbursement rates increasing approximately 10% across all three billing codes.
- APCM eliminates minute-tracking requirements, instead using 13 service elements that must be available to enrolled patients each month.
- Three HCPCS base codes (G0556, G0557, G0558) cover all Medicare beneficiaries from zero chronic conditions to complex QMB patients, with reimbursement ranging from approximately $16 to $117 per patient per month.
- Three new 2026 behavioral health add-on codes (G0568, G0569, G0570) allow practices to layer Collaborative Care Model and BHI services on top of APCM, generating up to approximately $263 per patient per month.
- APCM cannot be billed concurrently with CCM, PCM, or TCM for the same patient in the same month, but CAN be billed alongside RPM, creating a combined revenue opportunity of approximately $170 to $260+ per patient per month.
Nearly four in five Medicare beneficiaries live with two or more chronic conditions. For primary care practices managing these patients, the challenge has never been clinical willingness. It has been administrative burden: tracking minutes, documenting time thresholds, and navigating overlapping code requirements across CCM, PCM, and TCM. These friction points have kept thousands of practices from participating in care management programs at all.
Advanced Primary Care Management was designed to eliminate that friction. CMS launched APCM on January 1, 2025, as a bundled monthly payment that replaces minute-tracking with 13 service elements. The program combines the clinical value of Chronic Care Management, Principal Care Management, and Transitional Care Management into a single billing framework, giving primary care providers a simpler pathway to reimbursement for the care coordination work they are already doing.
The 2026 Medicare Physician Fee Schedule Final Rule made APCM even more compelling. CMS finalized approximately 10% reimbursement increases across all three APCM codes and introduced three new behavioral health add-on codes (G0568, G0569, G0570) that allow practices to layer Collaborative Care Model and BHI services on top of APCM for the first time.
This guide covers every APCM billing code, reimbursement rate, service element requirement, implementation step, and compliance consideration your practice needs to know for 2026.
What Is APCM and Why It Matters
Advanced Primary Care Management is Medicare's activity-based care management program that pays primary care practices a monthly bundled payment for delivering coordinated, patient-centered care. Unlike time-based programs like CCM, APCM does not require practices to track and document specific minutes of clinical staff time. Instead, APCM requires that 13 service elements be available to enrolled patients, with appropriate services delivered when clinically indicated.
CMS designed APCM as a bridge between traditional fee-for-service billing and full value-based care. The program introduces population health concepts, including risk stratification, gap analysis, and performance measurement, to practices accustomed to volume-based billing. CMS has stated its goal: all Medicare beneficiaries in accountable care relationships by 2030. APCM is the on-ramp.
Who Can Bill for APCM
APCM is restricted to primary care providers who serve as the continuing focal point for all of a patient's healthcare needs. Eligible billing practitioners include physicians, nurse practitioners (NPs), physician assistants (PAs), and clinical nurse specialists (CNSs) practicing in primary care specialties such as family medicine, internal medicine, geriatrics, and general practice. Federally Qualified Health Centers (FQHCs) and Rural Health Clinics (RHCs) are also eligible.
Auxiliary personnel, including nurses, medical assistants, and care coordinators, can furnish APCM services under general supervision, consistent with incident-to billing rules. The billing practitioner does not need to personally perform every service element each month.
Patient Eligibility
All Medicare beneficiaries are eligible for APCM. The program is not limited to patients with chronic conditions. CMS established three tiers based on patient complexity:
| Level | Patient Profile | HCPCS Code |
|---|---|---|
| Level 1 | Patients with one or fewer chronic conditions | G0556 |
| Level 2 | Patients with two or more chronic conditions expected to last at least 12 months, placing the patient at significant risk | G0557 |
| Level 3 | Level 2 patients who are also Qualified Medicare Beneficiaries (QMB) | G0558 |
The chronic condition definition aligns with CCM: conditions expected to last at least 12 months or until death, placing the patient at significant risk of death, acute exacerbation, decompensation, or functional decline. QMB patients have no copay for APCM services, making them particularly well-suited for enrollment.
APCM Billing Codes and 2026 Reimbursement Rates
CMS established three HCPCS base codes for APCM, stratified by patient complexity. The 2026 Physician Fee Schedule delivered approximately 10% increases across all three codes.
| HCPCS Code | Level | Patient Profile | Approx. 2026 Rate | 2025 Rate |
|---|---|---|---|---|
| G0556 | Level 1 | 0-1 chronic conditions | $16 | $15 |
| G0557 | Level 2 | 2+ chronic conditions | $54 | $49 |
| G0558 | Level 3 | 2+ conditions + QMB | $117 | $107 |
One code per patient per month. If a patient's status changes (e.g., they enroll in the QMB program), adjust the code accordingly.
New for 2026: Behavioral Health Add-On Codes
The 2026 Physician Fee Schedule introduced three new HCPCS codes that can be billed as add-on services alongside any APCM base code. These codes are designed to be directly comparable to existing BHI and CoCM CPT codes, but without the time-based requirements.
| HCPCS Code | Description | Based On | Approx. 2026 Rate |
|---|---|---|---|
| G0568 | Initial month CoCM services for APCM patients | CPT 99492 | $162 |
| G0569 | Subsequent month CoCM services for APCM patients | CPT 99493 | $146 |
| G0570 | General BHI services for APCM patients | CPT 99484 | $57 |
These add-on codes do NOT have the time-based documentation requirements associated with their CPT counterparts. They are billed monthly alongside the APCM base code for the same patient. G0568 is used for the initial month of collaborative care; G0569 is used for all subsequent months.
Revenue Scenarios by Patient Profile
The following table illustrates how APCM reimbursement scales based on patient complexity and behavioral health needs.
| Patient Scenario | Codes Billed | Approx. Monthly Revenue |
|---|---|---|
| Healthy patient, preventive care only | G0556 | $16 |
| Standard patient, 2+ chronic conditions | G0557 | $54 |
| QMB patient, 2+ chronic conditions | G0558 | $117 |
| 2+ conditions + initial CoCM | G0557 + G0568 | $216 |
| 2+ conditions + subsequent CoCM | G0557 + G0569 | $200 |
| 2+ conditions + general BHI | G0557 + G0570 | $111 |
| QMB patient + subsequent CoCM | G0558 + G0569 | $263 |
| 2+ conditions + RPM (layered) | G0557 + 99454 + 99457 | $153 |
| QMB + RPM + BHI add-on (max) | G0558 + G0570 + 99454 + 99457 | $273 |
At scale: A primary care practice with 500 Medicare patients enrolled in APCM under the most common code (G0557) generates approximately $27,000 per month, or $324,000 per year. Adding RPM for 200 of those patients at the standard tier (99454 + 99457) adds approximately $19,800 per month, bringing total annual care management revenue to approximately $561,600.
The 13 Required Service Elements
To bill any APCM code, your practice must be capable of delivering all 13 service elements. Not all elements must be provided every month, but all must be available to enrolled patients when clinically indicated.
| # | Service Element | Description |
|---|---|---|
| 1 | Patient consent and information | Inform the patient of APCM availability, single-provider rule, and right to stop services |
| 2 | Initiating visit | Face-to-face visit for new patients or those not seen within 3 years (AWV can qualify) |
| 3 | 24/7 access and continuity | 24/7 access to care team for urgent needs with real-time medical information access |
| 4 | Comprehensive care management | Systematic assessment of medical and psychological needs, coordination across providers |
| 5 | Care plan development | Electronic, patient-centered comprehensive care plan established and maintained |
| 6 | Care plan sharing | Care plan shared with patient/caregiver and other involved providers |
| 7 | Care transitions management | Support during transitions between care settings (discharge, referrals) |
| 8 | Medication management | Oversight of all medications, reconciliation, and adherence support |
| 9 | Ongoing communication | Regular patient contact through calls, portal messages, or in-person touchpoints |
| 10 | Enhanced communication | Technology for patient engagement (secure messaging, remote check-ins, virtual visits) |
| 11 | Population data analysis | Analyze patient population data to identify gaps in care at the panel level |
| 12 | Risk stratification | Stratify patients by risk level; high-risk patients receive more intensive management |
| 13 | Performance measurement | Track and report quality metrics aligned with CMS value-based care initiatives |
APCM vs. CCM: Key Differences
Understanding when to use APCM versus CCM is essential for maximizing reimbursement while maintaining compliance. The two programs cannot be billed for the same patient in the same month.
| Dimension | APCM | CCM |
|---|---|---|
| Time tracking required | No (activity-based) | Yes (20-60+ minutes per month) |
| Patient eligibility | All Medicare beneficiaries (0+ conditions) | 2+ chronic conditions only |
| Provider restriction | Primary care only | Any billing practitioner |
| Billing model | Monthly bundled payment | Time-based CPT codes |
| Most common code rate | G0557: approximately $54/month | 99490: approximately $66/month |
| Maximum monthly (single patient) | G0558: approximately $117/month | 99487: approximately $144/month |
| BHI integration | Add-on codes G0568/G0569/G0570 (new 2026) | Bill BHI codes separately (99484, 99492-99494) |
| Can bill with RPM | Yes | Yes |
| Can bill with each other | No. APCM and CCM are mutually exclusive for the same patient in the same month. | |
When to choose APCM over CCM: APCM is better suited for primary care practices that want to eliminate minute-tracking, enroll patients with fewer than two chronic conditions (Level 1), or take advantage of the new BHI add-on codes. CCM may still be more financially advantageous for practices with dedicated clinical staff who can consistently document 40-60+ minutes per patient per month, as CCM rates per code are higher.
Common APCM Claim Denials and How to Avoid Them
| Denial Reason | What Triggers It | How to Prevent It |
|---|---|---|
| Non-primary care provider | Specialist or non-PCP billing an APCM code | Verify billing practitioner is in an eligible primary care specialty before enrollment |
| Concurrent CCM or PCM billing | APCM and CCM (or PCM/TCM) billed for the same patient in the same month | Build mutual exclusion rules in billing system; choose one program per patient per month |
| Missing initiating visit | No qualifying face-to-face visit for new patients or those not seen within 3 years | Verify initiating visit status at enrollment; AWV qualifies if performed by APCM billing provider |
| Missing patient consent | No documented consent for APCM enrollment | Standardize consent template; obtain before first billing cycle |
| Incorrect level assignment | Billing G0558 (QMB) for a patient without QMB status | Verify QMB status through eligibility check before assigning Level 3 code |
| BHI add-on without base code | G0568/G0569/G0570 billed without a corresponding APCM base code in the same month | Always pair add-on codes with G0556, G0557, or G0558 |
Layering APCM with RPM
APCM and Remote Patient Monitoring can be billed concurrently for the same patient in the same month. This is one of APCM's most significant financial advantages: unlike CCM, which also pairs with RPM, APCM eliminates the minute-tracking requirement on the care management side while still allowing full RPM billing.
Consider a Medicare patient with hypertension, Type 2 diabetes, and depression enrolled in both APCM and RPM:
- APCM (G0557 for 2+ chronic conditions): approximately $54 per month
- APCM BHI add-on (G0570 for depression management): approximately $57 per month
- RPM device supply (99454 for 16+ days of BP and glucose monitoring): approximately $47 per month
- RPM management (99457 for 20 min clinical review): approximately $52 per month
Combined monthly revenue: approximately $210 per patient. At 200 patients, that is approximately $42,000 per month or $504,000 per year.

How to Implement APCM in Your Practice
Step 1: Verify Eligibility and Establish Infrastructure
Confirm your practice qualifies as a primary care provider under CMS definitions. Ensure your EHR supports electronic care plans, population data analysis, and risk stratification. Verify you can provide 24/7 access for patient urgent needs.
Step 2: Identify and Stratify Your Medicare Panel
Query your EHR for all Medicare patients. Assign each to a Level (1, 2, or 3) based on chronic condition count and QMB status. Prioritize enrollment for Level 2 and Level 3 patients, as they generate the highest per-patient revenue.
Step 3: Obtain Consent and Conduct Initiating Visits
APCM consent is separate from CCM consent. Obtain written or verbal consent before the first billing cycle, including notification that only one practitioner may bill APCM per month. Conduct initiating visits for new patients or those not seen within 3 years.
Step 4: Deliver the 13 Service Elements
Operationalize all 13 elements across your clinical workflow. Not every element is delivered every month, but all must be available. Focus on comprehensive care plans, medication management, care transitions, and ongoing patient communication.
Step 5: Layer with RPM and BHI Add-Ons
For patients with conditions requiring physiologic monitoring, add RPM. For patients with comorbid behavioral health conditions, add G0568/G0569/G0570. Each additional program increases per-patient revenue while improving clinical outcomes.
Step 6: Partner with a Managed Care Provider
Most primary care practices lack the operational capacity to deliver all 13 APCM elements, manage RPM devices, and coordinate BHI services simultaneously. Nsight Health's W2 clinical team handles all care coordination, documentation, and billing across all six CMS programs. Schedule a demo to see how we can operationalize APCM for your practice.
FQHC, RHC, and CAH Billing for APCM
FQHCs and RHCs can bill for APCM using the same HCPCS codes (G0556, G0557, G0558) at the national non-facility PFS payment rates. The BHI add-on codes (G0568, G0569, G0570) are also available. FQHCs and RHCs may bill APCM instead of CCM where it simplifies their workflows, but cannot bill both for the same patient in the same month.
Critical Access Hospitals (CAHs) can bill for APCM services by assigning the patient to an outpatient primary care billing practitioner. All standard APCM requirements, including the 13 service elements, initiating visit, and patient consent, apply regardless of facility type.
Compliance Considerations
APCM participation requires meeting CMS value-based care reporting thresholds. Practices billing APCM must report performance on the Value in Primary Care MIPS Value Pathway (MVP) beginning in 2026 for the 2025 performance year. Practices must also participate in one of the following: a Medicare Shared Savings Program ACO, a REACH ACO, the Making Care Primary model, or the Primary Care First model.
- No concurrent billing: APCM cannot be billed in the same month as CCM, PCM, TCM, interprofessional internet consultation, remote evaluation of patient videos/images, virtual check-ins, or e-visits for the same patient
- Single provider rule: Only one practitioner may bill APCM for a given patient per calendar month
- Primary care only: The billing provider must be responsible for all of the patient's primary care needs and serve as the continuing focal point for healthcare services
- Consent documentation: APCM requires its own consent, separate from any existing CCM or RPM consent
- Service element capability: Practices must demonstrate capability to deliver all 13 service elements, even if not all are provided every month
- Add-on code pairing: G0568, G0569, and G0570 may only be billed when a base APCM code is also reported for the same patient in the same month
Nsight Health's compliance infrastructure ensures all APCM billing meets CMS standards, including automated program exclusion checks, consent tracking, and service element documentation. Schedule a demo to learn how our compliance-first approach protects your practice.
Frequently Asked Questions
Q: Can I bill APCM and CCM for the same patient in the same month?
A: No. APCM and CCM are mutually exclusive. You must choose one program per patient per calendar month. You can alternate between programs in different months if clinically appropriate.
Q: Can I bill APCM and RPM for the same patient in the same month?
A: Yes. APCM and RPM address different clinical dimensions and have separate documentation requirements. Both can be billed for the same patient in the same month when all requirements for each program are independently met.
Q: Do I need to track minutes for APCM?
A: No. APCM is activity-based, not time-based. You must make 13 service elements available to enrolled patients, but there is no minimum time threshold to meet each month.
Q: What is the difference between G0557 and G0558?
A: Both codes are for patients with two or more chronic conditions. G0558 is specifically for patients who also hold Qualified Medicare Beneficiary (QMB) status. QMB patients have no copay, and G0558 reimburses at approximately $117 vs. $54 per month.
Q: Can specialists bill for APCM?
A: No. APCM is restricted to primary care providers who serve as the continuing focal point for all of a patient's healthcare needs.
Q: When were the BHI add-on codes (G0568, G0569, G0570) introduced?
A: These codes were finalized in the CY 2026 Physician Fee Schedule Final Rule and became effective January 1, 2026.
Q: How does Nsight Health support APCM implementation?
A: Nsight Health provides the clinical staff, documentation infrastructure, compliance oversight, and billing support to operationalize APCM alongside RPM, BHI, and all other CMS care management programs.
