What is Advanced Primary Care Management?
Advanced Primary Care Management (APCM) is a monthly Medicare service framework for participating primary care practices. It bundles specified care-management capabilities into a monthly service rather than requiring time-based billing for each activity.
CMS describes three APCM HCPCS codes—G0556, G0557, and G0558—selected according to the patient’s chronic-condition profile and, for the highest level, Qualified Medicare Beneficiary status. Read the current definitions on the CMS APCM service page.
Practices comparing care-management models can also review our APCM versus CCM comparison. For the monthly coding and review workflow, see the APCM billing guide.
Who can bill APCM services?
CMS says APCM may be billed by a physician or eligible non-physician practitioner who is responsible for the patient’s primary care and serves as the continuing focal point for the patient’s needed health care services. The codes are primarily intended for primary care specialties such as family medicine, general internal medicine, geriatrics, and pediatrics.
A practice should verify practitioner eligibility, enrollment, scope-of-practice rules, incident-to requirements, and payer-specific guidance before launch. APCM is not simply a monthly outreach code: the billing practitioner and practice need the capability to furnish the full service framework when clinically appropriate.
APCM requirements to verify before launch
Patient and practitioner eligibility
Establish who can furnish and bill the service, how patients are attributed, and how your practice will confirm the appropriate code level each month.
Consent and initiating-visit rules
Build a documented consent workflow and confirm when an initiating visit is required. Use current CMS guidance and have counsel review patient-facing language.
Service capabilities
Map responsibility for access, care continuity, care management, a patient-centered care plan, transition management, communication, and population-level management.
Overlap and payer rules
Check service conflicts, payer-specific edits, locality, and Medicare Administrative Contractor guidance before final coding or submission.
Population-level management
Establish a repeatable way to identify care gaps, risk-stratify the population, and target services using diagnoses, claims, or other electronic data.
Performance measurement
Confirm how the practice will satisfy current performance-measurement requirements, including any applicable MIPS Value Pathway or model-participation route.
A practical APCM implementation plan
- Define governance. Name the clinical, operational, compliance, and billing owners. Document which decisions require practice approval.
- Design patient enrollment. Define eligibility screens, initiating-visit checks, consent, patient communications, and opt-out handling.
- Build the monthly loop. Specify outreach, structured documentation, care-team tasks, escalation, closure, care-plan updates, and continuity expectations.
- Review before billing. Assemble evidence, candidate code, conflicts, and exceptions for a qualified practice reviewer before any claim is submitted.
- Measure and improve. Review enrollment, completion, escalations, care gaps, patient experience, and billing outcomes. Update the workflow when CMS, MAC, or payer guidance changes.
APCM documentation and operating controls
Documentation should show what was furnished for the individual patient and support the practice’s monthly review. CMS describes APCM as person-centered: the clinically appropriate elements vary by patient, but the practice must maintain the capability to furnish the required service framework.
- Eligibility and code-selection logic with an accountable human owner
- Consent status, source, date, and withdrawal process
- Initiating-visit status and the evidence used to determine whether one was required
- Urgent-symptom and safety escalation rules
- Task ownership, due times, disposition, and closure evidence
- Patient interactions, care-plan changes, coordination, and transition follow-up
- Monthly billing-review sign-off and audit trail
APCM program questions practices ask
Is APCM time based?
No. CMS describes APCM as a monthly bundle without the minute-by-minute thresholds used by individual care-management codes. The service requirements still apply.
Does every element happen every month?
Services are furnished as clinically appropriate for the patient. The practice must maintain the capability to provide the required elements during a billed month.
Is consent required?
Yes. CMS requires written or verbal consent before services begin and documentation of that consent in the medical record.
Can a vendor run the whole program?
Vendors can support operations, but the billing practitioner and practice retain responsibility for clinical care, required capabilities, documentation, and billing.
