How APCM Is Changing Primary Care & What to Do Now

Many primary care practices still operate outside value-based programs or hybrid payment models that provide the support needed to build advanced, longitudinal primary care. That gap reflects a reimbursement structure that has historically paid for visits, not for the care coordination, follow-up, and proactive patient management that happen between them.

Advanced Primary Care Management (APCM), introduced in the 2025 Medicare Physician Fee Schedule, represents the Centers for Medicare and Medicaid Services' (CMS) most direct attempt to change that. Part of its goal is to have 100% of Traditional Medicare beneficiaries in accountable care relationships by 2030.

Rather than tying payment to documented monthly minutes, APCM reimburses primary care organizations for maintaining the capabilities needed to support patients between visits: care coordination, discharge follow-up, digital access, and population-level management.

For primary care leaders, that makes APCM more than a new billing option. It is a decision about whether the practice can support a broader, more structured model of between-visit care across its Medicare population.

This guide breaks down how APCM is changing primary care, what practices need in place before launching, where implementation tends to become difficult, and how to decide whether APCM, CCM, or a combination of both is the right fit.

Why APCM matters now

Primary care is being asked to do more between visits

Primary care is being asked to offer multiple services beyond the exam room, even though primary care accounts for just 4% of total healthcare spending. Practices are now expected to coordinate care across settings, follow up after hospital discharges, address patients' social needs, identify gaps in preventive care, and remain accessible between appointments. For many practices, that work is already happening informally, but without a payment structure designed to support it.

As a result, between-visit coordination, follow-up, and proactive outreach often go unreimbursed, leaving practices to subsidize the work or let needs go unmet. APCM matters because it is one of CMS’s clearest efforts to align reimbursement with the broader care management role primary care is already expected to play.

APCM reflects a broader shift in what Medicare encourages primary care providers to own

APCM is not just another monthly billing code layered onto other fee-for-service codes. Rather, it represents a transition to a model where primary care practices must actively manage a patient’s health between visits. This includes driving ongoing care coordination, transitional support after discharge, digital patient access, population-level gap management, and participation in a quality framework tied to outcome accountability.

APCM consolidates capabilities that were previously spread across separate programs, including Chronic Care Management (CCM), Transitional Care Management (TCM), Principal Care Management (PCM), and several digital communication services, into a single, integrated model anchored to a patient's primary care provider. Medicare is now reimbursing for a more continuous, team-based model of primary care, not just the individual interactions within it.

How APCM is changing primary care

APCM replaces time-based monthly billing with service-based care management

Under CCM, reimbursement depends on documented time. If clinical staff spend at least 20 minutes in a month coordinating a patient’s care, the practice can bill. APCM changes that structure. Instead of paying for documented monthly time, it reimburses practices for maintaining a defined set of care management capabilities that are available to enrolled patients on an ongoing basis.

That means APCM is not billed based on whether a patient used every service in a given month. It is billed based on whether the practice is maintaining the service model required to support that patient population.

APCM changes how practices operationalize care management

Under CCM, care management can be run patient by patient: identify eligible patients, document qualifying monthly activity, and bill once the time threshold is met. APCM is broader than that. Though patients still must choose to enroll, the model expects practices to maintain a care model that is operational across an entire enrolled Medicare population. They must still document individual patient interactions month to month, but must document service availability instead of time spent.

That changes what has to be in place behind the scenes. Instead of focusing primarily on time tracking, practices need reliable workflows for patient attribution, stratification, discharge follow-up, care planning, outreach, and quality reporting. In other words, APCM is not just a different billing structure. It is a different operating model for between-visit care.

APCM expands care management beyond patients with multiple chronic conditions

CCM requires patients to have two or more chronic conditions to qualify. Under APCM, any Medicare patient can enroll, regardless of how many chronic conditions they have.

To account for differences in clinical and social complexity, CMS stratifies APCM patients into three levels:

• Level 1: Patients with zero or one chronic condition(s) 
• Level 2: Patients with two or more chronic conditions
• Level 3: Qualified Medicare Beneficiaries (QMBs) with two or more chronic conditions

Each level carries a different monthly reimbursement rate, with Level 3 reflecting the more intensive support these patients typically require. This structure allows practices to extend between-visit care across a broader Medicare population while aligning reimbursement with the complexity of each patient's needs.

APCM makes discharge support, care coordination, and digital access more central to primary care

APCM raises the bar for what primary care practices are expected to own once a patient leaves the office. Several capabilities that were previously optional or handled through separate programs are now built directly into the APCM service model:

• Post-discharge follow-up: Practices must coordinate care transitions after hospital, emergency department, or skilled nursing facility discharges, including timely follow-up and ongoing transitional support.
• Medication reconciliation: Care teams are responsible for reviewing and coordinating medications across care settings, reducing the risk of errors or gaps in adherence.
• Digital communication: APCM requires two-way digital communication options, including secure messaging, text, patient portals, telehealth, and the ability for patients to submit images or other information to their care team.
• Community and SDOH resource coordination: Practices must actively connect patients to home-based care, community services, and Social Determinants of Health (SDOH) resources such as transportation, food access, and housing support.

Each of these expectations requires defined workflows, dedicated staff, and reliable systems. For many practices, APCM makes between-visit care a more formal part of primary care operations.

APCM ties care management more closely to population health and quality performance

APCM is not designed for reactive, patient-by-patient care management. It expects practices to take a population-level view: using analytics to identify care gaps, stratify patients by risk, design interventions, and measure outcomes across the enrolled Medicare population.

This population health requirement is paired with a mandatory quality framework. To bill compliantly for APCM, practices must participate in one of the following:

• The Value in Primary Care MIPS Value Pathway (MVP)
• An Accountable Care Organization (ACO)
• An Advanced Alternative Payment Model (AAPM)
• An FQHC or RHC quality program

This is a meaningful distinction from CCM, which can support quality improvement but does not require participation in a specific quality program. APCM is designed for practices moving toward outcomes-based accountability, and the quality reporting requirement reflects that intent directly.

APCM assumes the primary care practice is the patient's focal point of care

APCM can only be billed by the provider serving as the patient’s designated focal point of care. That means the billing practice is taking responsibility for longitudinal primary care across settings, not just delivering a discrete care management service.

For primary care organizations, this is often a natural extension of the role they already play. For specialists, it creates a significant limitation. Unless a specialty practice is willing to assume full primary care responsibility for a patient, APCM is generally not the right fit.

What practices need to have in place before launching APCM

Patient identification, stratification, and enrollment workflows

Before billing can begin, your practice needs a reliable process for identifying eligible Medicare patients, assigning them to the correct APCM level, documenting consent, and ensuring each patient is enrolled under only one provider at a time.

Stratifying patients accurately matters both for compliance and for reimbursement. Level 3 billing, the highest reimbursement tier, requires identifying patients with Qualified Medicare Beneficiary status, which typically involves practice access to the HIPAA Eligibility Transaction System (HETS) database or another compliant eligibility verification workflow. Without a reliable eligibility workflow, your practice risks miscoding patients or missing those who qualify for the highest level of support.

Care management staffing, care plans, and 24/7 patient support

APCM requires more than a documented care management policy. Practices need the staff and infrastructure to sustain between-visit support month after month, including:

• An electronic, patient-centered care plan that is accessible to the patient and updated regularly by the care team
• Care managers or clinical staff responsible for outreach, coordination, and follow-up
• 24/7 access infrastructure, whether through a dedicated care line, on-call staff, or a partner providing that coverage
• Ongoing patient engagement between visits, not just reactive responses to patient-initiated contact

For organizations that have never run a formal care management program, this ongoing support is often the most significant operational lift. It requires designated staff to own each capability during days, nights, and weekends, not just an expectation that existing front-office or clinical staff will absorb the work.

Discharge monitoring and care transition workflows

APCM's transitional care expectations require your practice to know when patients have been hospitalized or discharged, and to respond quickly. That means having:

• Timely discharge notification alerts
• A defined workflow for prompt follow-up after discharge
• Processes for medication reconciliation during transitions
• Transitional coordination for patients returning from inpatient settings to the home

Without reliable alerts and a dedicated workflow, these transitions are easy to miss. And missed transitions are one of the most direct paths to avoidable readmissions.

Data, analytics, and quality reporting infrastructure

APCM's population health and quality requirements depend on data infrastructure that many practices do not yet have fully in place. Running a compliant program requires:

• Care-gap reporting across the enrolled Medicare population
• Patient risk stratification informed by clinical and claims data
• Integration of EHR, claims, and other data inputs to support care decisions
• Documentation and reporting aligned with the Value in Primary Care MVP, ACO, or AAPM requirements

Practices that rely heavily on manual processes or operate with fragmented data systems will find these requirements particularly difficult to meet consistently. APCM's quality reporting obligation is not optional; it is a compliance requirement tied directly to the program's billing legitimacy.

Digital communication and community resource coordination

APCM requires patients to have ongoing access to the care team through multiple communication channels, which may include phone, portal messaging, secure digital messaging, telehealth, and patient-submitted information.

Beyond communication tools, your practice also needs established referral pathways to community-based organizations, home care providers, and SDOH resources. Connecting a patient to transportation assistance or food access programs requires knowing which resources exist, how to make referrals, and how to document that coordination in the patient's record. APCM expects that infrastructure to be in place, not assembled on a case-by-case basis.

Common operational challenges in APCM

Billing APCM is only one part of the equation. Delivering the full service model across an enrolled Medicare population depends on the workflows, staffing, and systems behind the program.

Discharge follow-up and transition visibility

A practice cannot coordinate timely transitional care if it does not know a patient has been admitted, discharged, or transferred in the first place. That means APCM often depends on more than a documented follow-up policy. It depends on access to reliable discharge alerts, clear ownership of follow-up tasks, and enough staffing capacity to act quickly when transitions occur.

Eligibility verification and Level 3 stratification

Level 3 reimbursement can be meaningful, but only if the practice can accurately identify Qualified Medicare Beneficiaries and support that stratification with reliable eligibility workflows. That makes HETS access, eligibility verification, and stratification workflows important.

Managing a broader eligible patient population

Because APCM is not limited to patients with multiple chronic conditions, it can expand the scope of care management quickly. Practices need a clear plan for who is eligible to be offered the chance to enroll, how outreach will take place, and whether staffing can support that broader patient panel.

Quality reporting and value-based participation

Once APCM is tied to MVP, ACO, AAPM, or FQHC/RHC quality participation, it is no longer just a monthly care management service. It becomes part of a broader value-based operating model with reporting, accountability, and performance implications that may reach well beyond the care management team.

Staffing 24/7 access and ongoing outreach

Continuous access and proactive outreach are easy to list on paper but harder to sustain operationally. Practices need a realistic staffing model for after-hours needs, ongoing patient engagement, and care plan maintenance over time.

These operational demands often determine whether APCM is sustainable in practice. For organizations that need support with patient outreach, discharge follow-up, care coordination, and the underlying staffing model, care management vendors like ChartSpan can help practices fill those gaps without requiring the practice to build the entire program internally.

How APCM supports financial sustainability in primary care

APCM creates a monthly, recurring reimbursement for the longitudinal work that’s historically gone unfunded in primary care: care coordination, discharge follow-up, and proactive outreach between visits. Because payment is tied to maintaining a service model rather than logging monthly minutes, that revenue is more predictable than individual fee-for-service billing, which only pays for the work that happens to fall inside a visit or for work that is time-tracked, in the case of Chronic Care Management.

Reimbursement is structured around three patient levels, each tied to a specific APCM billing code and monthly payment rate that varies by geographic location:

Level	HCPCS Code	Approximate 2026 National Average Reimbursement*
Level 1	G0556	~$16.37 per patient, per month
Level 2	G0557	~$53.78 per patient, per month
Level 3	G0558	~$117.24 per patient, per month

*Revenue may vary by provider.

These tiers are designed to reflect complexity, not just chronic condition count. QMBs with multiple chronic conditions are more likely to need help with medication access, transportation, post-discharge coordination, and connections to community-based resources. The higher Level 3 reimbursement accounts for the added staff time, outreach, and coordination that level of support requires. For practices serving a large QMB population, such as Federally Qualified Health Centers (FQHCs), that reimbursement design can represent a meaningful share of total APCM revenue.

That said, reimbursement alone doesn't create financial sustainability. APCM pays for maintaining a service model, which means the revenue only materializes if a practice can actually deliver it: enrollment, stratification, discharge visibility, 24/7 access, and quality reporting all have to be running consistently, month over month. For practices without that infrastructure already in place, the more relevant question isn't whether APCM pays fairly; it's whether the practice can operationalize what it's being paid to do.

Should your practice start with APCM, CCM, or both?

When APCM makes sense

APCM is a strong fit for primary care organizations that are ready to take ownership of between-visit care across a broader Medicare population, not just their highest-complexity chronic care patients. It tends to make the most sense for practices that:

• Already have, or can build, the staffing and workflows for ongoing care coordination and patient access
• Serve a meaningful number of QMBs or patients with significant social needs
• Are already participating in, or preparing to participate in, a value-based quality framework
• Want to support Medicare patients beyond the narrower chronic care population that qualifies for CCM
• Have access to the discharge visibility, analytics, and reporting infrastructure APCM requires

When CCM may still be the better starting point

APCM is not the right first move for every practice. CCM remains a strong option for organizations that are newer to care management, have a more limited infrastructure, or want to start with a narrower operational scope.

CCM may be the better fit if your practice:

• Is launching a care management program for the first time
• Primarily serves patients with two or more chronic conditions rather than a broader Medicare panel
• Does not yet have discharge notification workflows, analytics infrastructure, or consistent digital communication capabilities in place
• Includes specialty providers who want to offer care management but are not the patient’s focal point of care

It is also worth considering the financial mix of your Medicare population. APCM can create meaningful value for practices serving a substantial number of higher-complexity or QMB patients, but for organizations with fewer such patients and limited infrastructure, CCM may still be the more practical starting point.

Running APCM and CCM simultaneously

APCM and CCM are not mutually exclusive at the practice level, but they cannot be billed for the same patient in the same month. That means some organizations may choose to run APCM for one portion of their Medicare population and CCM for another, depending on patient eligibility, complexity, and operational fit.

That approach can make sense, but it also adds administrative complexity. Practices have to be confident in how patients are segmented, how enrollment is managed, and how each program’s requirements are being met without overlap.

How an APCM partner can support implementation

For many primary care organizations, APCM is less a question of interest than of execution. The challenge lies in building and sustaining the staffing, discharge workflows, patient engagement processes, eligibility verification, and quality reporting infrastructure the program requires.

That is where a care management partner can change the equation. A partner that already has the systems, staffing, and compliance processes needed to support APCM can help a practice launch the program without building every component from scratch.

How ChartSpan helps practices operationalize APCM

For practices that do not want to build the full APCM model internally, ChartSpan provides a managed APCM program built around the day-to-day work the model requires. Rather than asking practices to stand up every workflow themselves, ChartSpan helps support both the patient-facing and operational sides of APCM.

ChartSpan helps practices:

• Identify and stratify eligible patients, including support for QMB verification and enrollment
• Conduct ongoing patient outreach and care management between visits
• Maintain care plans, health goals, medication coordination, and appointment support
• Connect patients to transportation, food, housing, and other community resources when social needs affect care
• Provide 24/7 patient access to care managers through phone and text support
• Coordinate post-discharge follow-up with discharge alerts and transition support
• Support population health analytics and quality reporting tied to APCM performance requirements

That support can make APCM far easier to launch and sustain, especially for practices that want to expand between-visit care without building every workflow in-house. In primary care management programs, ChartSpan reports an average 45% patient enrollment rate and estimates more than $288,000 in net revenue* per 1,000 APCM-eligible Medicare patients. 

*Results may vary by provider.
