Advanced Primary Care Management: What Medicare Actually Requires

Medicare began paying for Advanced Primary Care Management on January 1, 2025. APCM gives qualifying primary care practitioners a monthly billing pathway for longitudinal care, care planning, coordination, access, population management, and performance measurement. It has no monthly minute threshold.

APCM is a monthly service. A billed month should be supported by medically necessary, patient-specific APCM work, documented in the medical record, while the practice maintains the full set of required capabilities.

The short version: Choose the correct patient tier, establish the billing practitioner's primary-care relationship, complete consent and any required initiating visit, maintain every APCM capability, furnish the elements appropriate to the patient that month, document the patient-specific work, and check for conflicting services before submitting one monthly base code.

CMS organizes APCM into 10 service elements. References to “13 APCM requirements” usually come from vendors splitting CMS subparts into a different checklist. Thirteen is not CMS's official framework.

The three APCM base codes

The three codes use patient complexity and Qualified Medicare Beneficiary status to set the level. Each tier uses the same service framework.

The CMS APCM overview summarizes the levels, and the CMS APCM FAQ confirms that G0556 includes patients with zero or one chronic condition.

Use current information for the service month. A problem list can identify likely candidates, but it cannot determine chronicity, clinical risk, or QMB status on its own. The billing practitioner remains responsible for the code reported.

QMB is a billing status as well as a tier criterion

QMB means Qualified Medicare Beneficiary. Only this specific Medicare Savings Program status establishes the G0558 tier. Other forms of dual eligibility do not. Practices should verify QMB for the date of service through an available Medicare eligibility response or another reliable source.

Federal law prohibits providers from billing a QMB patient for Medicare Part A or Part B deductibles, coinsurance, or copayments. The CMS QMB billing protections apply even when Medicaid does not pay the full cost-sharing amount.

There is no single APCM payment amount

APCM is paid monthly under the Medicare Physician Fee Schedule. The allowed amount depends on the code, year, locality, site of service, and other fee-schedule inputs. A national average or a single revenue projection should not be treated as the payment for every claim.

Who may bill APCM

A physician or Medicare-recognized nonphysician practitioner may bill APCM when that practitioner:

• Is responsible for all of the patient's primary care services.
• Serves as the continuing focal point for all needed health care services.
• Has obtained the patient's APCM consent.
• Meets the patient-specific and practice-level service requirements.

CMS identifies physicians, nurse practitioners, physician assistants, certified nurse-midwives, and clinical nurse specialists in the final rule. The practitioner's actual role matters more than the specialty label. A specialist managing one condition would not satisfy the standard unless that practitioner genuinely assumes responsibility for the patient's primary care and serves as the focal point for needed care.

APCM is a designated care-management service. Auxiliary personnel may furnish appropriate portions incident to the billing practitioner under general supervision. State scope-of-practice rules, Medicare incident-to rules, and the billing practitioner's responsibility still apply. Some clinical decisions and component services necessarily involve the practitioner.

Only one practitioner may furnish and receive payment for APCM for a patient in a calendar month.

The 10 service elements

The CY 2025 Physician Fee Schedule final rule established the service. CMS's current overview presents the same operational framework in a shorter format.

1. Beneficiary consent

Obtain verbal or written consent before APCM begins and document it in the medical record. The conversation should explain:

• The availability and ongoing monthly nature of APCM.
• The billing practitioner's responsibility for primary care and role as the focal point for needed care.
• That one practitioner can furnish and be paid for APCM in a calendar month.
• That Medicare cost sharing may apply.
• That the patient may stop APCM at any time, effective at the end of the month.
• That consent does not limit the patient's ability to receive covered care from other practitioners.

One valid consent ordinarily continues with the same APCM practitioner. A prior CCM consent does not transfer to APCM. Obtain new consent when the APCM billing practitioner changes.

2. Initiating visit

An initiating visit is required for a new patient unless the billing practitioner or another practitioner in the same practice saw the patient during the previous three years, or the practice furnished APCM, CCM, or PCM to the patient during the previous year.

A qualifying level 2 through 5 office or outpatient E/M visit, the face-to-face component of TCM, an Initial Preventive Physical Examination, or an Annual Wellness Visit can serve as the initiating visit. A qualifying Medicare telehealth visit may also satisfy the requirement. The practitioner who performs the initiating visit must be the practitioner who will furnish APCM, and APCM should be discussed during the visit.

The initiating visit is paid separately and occurs only when required at enrollment. When the practitioner uses billed TCM as the initiating service, the practitioner should begin APCM billing in a later, non-conflicting month because that same practitioner cannot report TCM and APCM for the same patient-month.

3. Around-the-clock access and continuity

Patients and caregivers need a way to reach the practice at any time for urgent needs. The practice also needs continuity with a designated care-team member and an alternative to traditional office-only care that fits its patient population, such as expanded hours, home-based care, or telehealth.

CMS's overview calls for real-time access to patient information. The final rule allows an after-hours responder to work without live EHR access in some cases. The responder must communicate the interaction to the primary care team and ensure it is documented in the medical record. The key operational question is whether urgent information reaches someone who can respond and whether the primary team receives the result.

4. Comprehensive care management

The practice performs a systematic assessment of medical and psychosocial needs as appropriate, supports receipt of preventive services, reconciles and manages medications, and oversees patient self-management.

This element is longitudinal. New diagnoses, medication changes, functional decline, caregiver strain, overdue prevention, and unmet social needs can all change the work required for a patient.

5. Electronic, patient-centered care plan

Develop, implement, maintain, and revise an electronic care plan when clinically applicable. The plan must be available inside and outside the billing practice as appropriate, and relevant care-team members must be able to access and update it. Give a copy to the patient or caregiver.

CMS does not prescribe one template or a fixed update interval. A useful plan commonly includes the problem list, prognosis, measurable goals, cognitive and functional status, symptom and medication management, planned interventions, self-management responsibilities, caregiver or environmental needs, outside resources, and follow-up needs. The contents should reflect the patient. Update the plan when the clinical situation, goals, treatment, or responsibilities change.

6. Management of care transitions

Coordinate referrals and follow-up after emergency department visits and discharges from hospitals, skilled nursing facilities, and other facilities. This includes timely electronic exchange of health information.

CMS expects reasonable efforts to communicate with the patient or caregiver within seven days of discharge when possible and clinically indicated. Document outreach attempts as well as completed interactions. The seven-day language should not be converted into a claim that successful contact is possible after every discharge.

7. Practitioner, home, and community coordination

Coordinate with clinicians, facilities, home- and community-based providers, and social-service organizations when the patient's needs call for it. Relevant documentation can include psychosocial strengths and needs, functional deficits, goals, preferences, desired outcomes, and cultural or linguistic considerations.

The purpose is to connect the care plan to the people and services carrying it out. A referral order by itself may leave the loop open.

8. Enhanced communication opportunities

Offer asynchronous communication beyond the telephone, such as secure messaging or a patient portal. Maintain the ability to support remote evaluation of prerecorded patient information, interprofessional consultation, and patient-initiated digital communication that requires clinical judgment.

Virtual check-ins and e-visits are examples in CMS policy. Practices maintain the communication capabilities appropriate to the requirement and use them according to patient need.

9. Population-level management

Analyze electronic population data to identify gaps in care. Risk-stratify the practice population using diagnoses, claims, or other electronic data, then target services and interventions where appropriate.

This is a practice-level capability. A workable implementation produces a reviewable panel, a defined method for prioritizing it, and a route from a detected gap to staff action.

10. Performance measurement

Measure primary-care quality, total cost of care, and meaningful use of Certified EHR Technology. CMS identifies the Value in Primary Care MIPS Value Pathway and participation in specified Medicare ACO or primary-care models as reporting pathways. Practices should confirm which current pathway applies to their clinicians and reporting year.

What must happen in a billed month

APCM has no minute floor and no prescribed monthly contact count. CMS also says every service element does not have to occur for every patient each month.

The monthly standard has three layers:

CMS illustrates this with a patient who has heart failure and chronic kidney disease. A stable month may involve communication about the care plan. A later month may include a hospitalization, medication changes, follow-up, laboratory work, several virtual contacts, and consultation with a cardiologist. The same Level 2 code can describe both months because APCM payment is based on the monthly service rather than accumulated minutes.

The practical lesson is simple. Let the patient's needs determine the work. Maintain the required operating capabilities every month, and record the patient-specific care that was actually furnished.

What belongs in the medical record

CMS does not require a special monthly APCM form. The chart should make the patient-specific service understandable to another reviewer.

Document, as applicable:

• APCM consent and the required disclosures.
• The qualifying initiating visit when one is required.
• The current electronic care plan and provision of a copy to the patient or caregiver.
• Assessments, medication work, preventive-care actions, and self-management support.
• Communications with the patient, caregiver, clinicians, facilities, and community organizations.
• The reason for each care-management or coordination action and its result.
• Transition outreach attempts and completed follow-up.
• After-hours interactions and communication back to the primary team.

Practice-wide evidence can live in policies, schedules, system configuration, contracts, reports, and other operational records. CMS does not direct practices to restate every practice-level capability in every patient chart each month. Submission of the claim is the billing practitioner's attestation that the code requirements were met.

Concurrent billing rules

The practitioner billing APCM may not separately report the following overlapping services for the same patient and calendar month:

• Chronic Care Management.
• Principal Care Management.
• Transitional Care Management.
• Interprofessional consultation.
• Remote evaluation of patient-submitted images or video.
• Virtual check-ins.
• Online digital E/M services or e-visits.

CMS limited this restriction to the APCM billing practitioner. A different practitioner, including another practitioner in the same practice, may furnish an overlapping service when it is medically reasonable and necessary.

Complementary services may be billed when each service is medically necessary, all independent requirements are met, and work is not counted twice. Community Health Integration, Principal Illness Navigation, health-related social-needs assessment, Remote Physiologic Monitoring, and Remote Therapeutic Monitoring are examples. For 2026 APCM months, the same practitioner reports qualifying Behavioral Health Integration or psychiatric Collaborative Care through G0568, G0569, or G0570. The standalone BHI and CoCM codes remain available for months outside APCM.

Review payer edits and current coding instructions before submission. A platform may see activity in one EHR while missing claims or work recorded elsewhere.

APCM and CCM remain separate options

A practice may continue using CCM, PCM, TCM, and communication-technology codes when those services better describe the care furnished. Select the appropriate billing pathway for the patient-month before submitting the claim.

Cost sharing

For Original Medicare, APCM is a Part B service. After the deductible, the patient generally owes 20% of the Medicare-approved amount. Supplemental coverage may pay some or all of that liability. Medicare Advantage coverage and cost sharing depend on the plan. Medicare's APCM coverage page gives the beneficiary-facing explanation.

QMB patients have no legal obligation to pay Medicare Part A or Part B cost sharing. This protection is particularly important for G0558 and should be reflected in patient communication and billing controls.

The 2026 behavioral-health add-ons

Beginning January 1, 2026, CMS created three optional add-on codes for practices furnishing APCM and qualifying behavioral-health services:

• G0568 for the initial psychiatric Collaborative Care Model month.
• G0569 for a subsequent psychiatric Collaborative Care Model month.
• G0570 for general Behavioral Health Integration.

The same practitioner reports the add-on with G0556, G0557, or G0558 in the same month. Each add-on has its own staffing, service, and documentation requirements. Our source-verified behavioral-health add-on guide covers those rules in detail.

The CY 2026 Physician Fee Schedule final rule is the controlling policy source for these additions.

A practical readiness check

Before the first claim, a practice should be able to answer these questions with evidence:

1. Who is the APCM billing practitioner, and does that person hold the required primary-care relationship?
2. Which code applies, and what current condition and QMB information supports it?
3. Was an initiating visit required, and how was the requirement satisfied?
4. Where is the APCM-specific consent and what did the patient agree to?
5. Where is the electronic care plan, who can update it, and how was it provided to the patient or caregiver?
6. How do urgent after-hours contacts reach the care team and return to the chart?
7. How are transitions, referrals, medications, care gaps, and coordination work routed and documented?
8. How does the practice perform population analysis and risk stratification?
9. Which performance-measurement pathway applies?
10. How are same-month billing conflicts reviewed before submission?
