APCM vs. CCM: Key Differences, Codes, and Which to Bill

The short answer: APCM pays a flat monthly rate for coordinating your full primary care panel with no minute tracking, while CCM pays for at least 20 minutes of clinical staff time each month for patients with 2 or more chronic conditions. You can bill only one of the 2 for the same patient in the same calendar month.

TL;DR: APCM vs. CCM

Here's a quick side-by-side overview of Advanced Primary Care Management and Chronic Care Management before we dive deeper into the details below:

What Is APCM? Advanced Primary Care Management Explained

APCM is a monthly care management program introduced by the Centers for Medicare & Medicaid Services (CMS) in 2025 that pays a flat rate for coordination work, such as care planning and check-ins that happen outside the exam room, regardless of the number of visits.

Eligibility for APCM extends to all patients who consent to receiving the services, including those without a chronic diagnosis yet. Our advanced primary care management program page walks through how the model works day-to-day.

Let's see what the program includes:

APCM Service Elements and Care Model

For APCM, your practice has to serve as the one continuing point of contact for a patient's primary care, which becomes the place the patient and their other providers come back to when something needs coordinating.

CMS spells out the continuing point-of-contact role through 13 specific service elements your practice needs to have in place each month.

Here’s how the elements are grouped together and how the requirement changes the way your team documents and bills for the work:

• Consent, Access, and Continuity: Before anything else, APCM requires patient consent and, for new patients, an initiating visit. From there, your practice needs to stay reachable 24/7, continuous for the patient across visits, and open to delivering care in ways other than the traditional office appointment, such as home visits or expanded hours.
• Care Planning and Coordination: Your practice develops and maintains a patient-centered care plan, including a comprehensive assessment of the patient's medical and psychosocial needs and medication reconciliation. The plan includes ensuring the patient receives recommended preventive care and coordinating handoffs during care transitions, such as hospital discharge. Your team also stays in touch with the other home- and community-based providers involved in that patient's care, and your providers themselves stay reachable through secure messaging and e-visits, with virtual check-ins filling the gaps between appointments.
• Population-Level Reporting: Your practice also keeps tabs on the bigger picture, looking across the whole patient panel to spot who's at higher risk and how care is trending overall. This level of tracking keeps you audit-ready and helps you reach out to patients who need care promptly.

APCM Eligibility and Complexity Levels

Every Medicare beneficiary qualifies for APCM, and reimbursement scales with patient complexity.

CMS built 3 tiers using HCPCS (Healthcare Common Procedure Coding System) codes to reflect the difference:

• Level 1, Code G0556: Patients with 0-1 chronic conditions, at the lowest of the 3 monthly rates.
• Level 2, Code G0557: Patients with 2 or more chronic conditions, at a higher rate reflecting the added coordination needed.
• Level 3, Code G0558: Patients with 2 or more chronic conditions who also hold Qualified Medicare Beneficiary (QMB) status, where Medicaid assists with premiums, at the highest rate.

What Is CCM? Chronic Care Management Explained

CCM is Medicare's program for the ongoing, month-to-month coordination that patients with several chronic conditions need between visits, such as medication management and regular check-ins on how they're doing.

Billing and reimbursement for CCM are based on the clinical staff time your team actually puts into that work each month, unlike APCM's flat rate.

Here's what the program includes:

CCM Eligibility and Chronic Condition Rules

CCM eligibility depends more on the patient's clinical picture than on their Medicare status alone.

• 2 or More Long-Term Conditions: Patients should have 2 or more chronic conditions expected to last at least 12 months, or until death, with a meaningful risk of decline. If you're not sure whether a specific diagnosis counts, you can use a recent CCM eligibility guide to see the common ones that qualify.
• An Established Relationship: The patient needs a prior evaluation and management visit with your practice, in person or by telehealth.
• One Billing Provider Per Month: Only 1 practitioner can bill CCM for a given patient each month, even when several providers are involved in that patient's care.
• Documented Consent: Your patients should provide verbal or written consent, and you must ensure the consent is documented in the record before you bill for any service.

CCM Time and Documentation Requirements

CCM's payment structure ties directly to clock time, which makes accurate logging the backbone of a compliant program.

• 20 Minutes by Clinical Staff: Code 99490 covers the first 20 minutes of non-complex CCM by clinical staff under a physician's direction on a monthly basis.
• Add-On Time With 99439: Additional 20-minute blocks bill under 99439, up to twice per month alongside 99490.
• Physician-Personal Time With 99491: A physician or qualified healthcare professional personally providing 30+ minutes bills under 99491, with 99437 for each extra 30-minute block.
• An Ongoing Care Plan: Your team establishes and implements a plan that addresses chronic conditions and medications. The plan also covers psychosocial needs and gets revised as circumstances change.
• Documentation in the Medical Record: The time or care-plan work you log for CCM needs to be in the patient's record, using a certified EHR (Electronic Health Record). Your practice would need to show the documentation if a claim ever gets reviewed.

APCM vs. CCM Billing and Documentation Differences

Both programs pay for coordination work, but the mechanics behind that payment differ sharply.

Here are the differences:

Time-Based vs. Element-Based Care

CMS measures the work behind these 2 programs in very different ways:

• CCM Runs on the Clock: Every CCM code is tied to a set number of minutes, logged monthly to justify the claim.
• APCM Runs on Availability: APCM asks whether your practice makes the 13 defined service elements available each month, regardless of minutes spent, which moves records from time logs toward proving that those elements stayed in place.

Code and Reimbursement Comparison

Let’s see how the reimbursement rates and codes differ:

• CCM's Core Codes: 99490, 99439, 99491, and 99437 comprise the non-complex CCM family as per CMS's Chronic Care Management guidance. The reimbursement for these codes can vary widely, depending on the Medicare Administrative Contractor's locality and Qualifying Alternative Payment Model (APM) participation, among other factors. It's important to confirm your exact potential reimbursement using the current year’s CMS Physician Fee Schedule Lookup tool.
• APCM's 3 Codes: G0556, G0557, and G0558 scale from roughly $15 to over $100 monthly based on the tier and patient complexity. Reimbursement varies by Medicare Administrative Contractor locality and other factors, so it's worth confirming your exact rate with the same CMS Physician Fee Schedule Lookup tool mentioned for CCM above.
• Where the Numbers Cross: CCM usually pays more than APCM's cheapest tier. However, APCM's top tier can outpay CCM for the same patient.

Cost-Sharing and Consent

Patients bear some of the medical costs under both programs. Consent is a separate requirement your practice needs to track on its own.

Here's what these aspects look like in practice:

• Standard Cost-Sharing Applies: Both APCM and CCM allow deductibles, copays, and coinsurance. Your team must explain these costs when enrolling every patient.
• QMB Protection Under APCM Level 3: Patients at APCM's highest tier avoid direct billing for cost-sharing, since QMB status already covers those costs through Medicaid.
• Separate Consent Requirements: APCM requires its own consent even when a patient has already agreed to CCM or Remote Patient Monitoring. Consent never transfers between the 2 programs.

APCM vs. CCM for Different Patients and Practices

Choosing between these programs gets easier once you match the model to your actual panel and practice structure.

Best Fit by Patient Complexity

Patient complexity offers the clearest signal for which program to use:

• Zero or One Condition Points to APCM: Since CCM requires 2 or more chronic conditions, patients below that threshold are only eligible for APCM's Level 1.
• Multiple Conditions Open Both Options: Patients with 2 or more chronic conditions qualify for either, and the decision often hinges on staffing capacity.
• High-Acuity, Low-Income Patients Lean Toward APCM: When a patient is juggling several chronic conditions and also happens to be a Qualified Medicare Beneficiary (QMB), APCM's top tier pays your practice the most for that patient while making sure they don't get billed for any of it themselves. This is possible because QMB status means Medicaid already covers the patient’s Medicare cost-sharing.

Best Fit by Practice Type

Your practice type narrows the decision even further:

• Primary Care Practices Can Choose Either: Family medicine, internal medicine, and geriatrics practices qualify for both. Many primary care practices apply APCM at a broad level and reserve CCM for the most intensive cases.
• Specialists Typically Default to CCM: Because APCM billing is limited to primary care specialties, specialists have to rely on CCM or a PCM program instead.
• FQHCs and RHCs Face a Fresh Decision: These facilities used to bill one blended rate through code G0511 for general care management, no matter which specific service they were actually providing. But now that G0511 is retired, they have to choose between APCM or CCM instead and bill for it the way independent practices do. Want to see how the facilities are adjusting? Check out our guide to FQHC remote monitoring.

APCM vs. CCM and Whether You Can Bill Both

Providers weighing the CCM vs APCM decision often ask whether they can layer these programs for the same patient. The answer depends on which service you're pairing.

Programs That Cannot Overlap in the Same Month

CMS built guardrails to prevent double-billing for overlapping work.

• No, You Can't Bill APCM and CCM in the Same Month: APCM can't be billed the same month as CCM, Principal Care Management, or Transitional Care Management for the same patient, since these services are already included in the APCM bundle. Billing any of these 3 separately for a patient who's also enrolled in APCM that month counts as double-billing for work Medicare already paid for once.
• Yes, You Can Switch Between Them Month to Month: The restriction only applies within a single calendar month. For example, a practice can bill APCM for a patient in July and CCM for that same patient in August if their needs change, as long as just one program and one billing provider are active in any given month.
• What Happens If You Bill Both Anyway: If your systems submit an APCM code and a CCM code for the same patient in the same month, Medicare catches the overlap and denies or claws back one of the two claims. This is exactly why it helps to build an automatic check into your coding and billing workflow, something more reliable than manually keeping track of which program covers each patient.

APCM or CCM Alongside RPM

Remote Patient Monitoring (RPM) falls outside the overlap restriction entirely.

• Yes, RPM Can Be Billed Alongside Either Program: RPM bills for device-based physiological data, a distinct category from care coordination time. Pairing it with APCM or CCM for the same patient in the same month is allowed and doesn't run afoul of the rules governing APCM, CCM, PCM, and TCM against each other.
• Pairing Adds Revenue and Clinical Insight: Practices that combine APCM or CCM with a Remote Patient Monitoring program gain a coordination framework and daily vitals data together. Your practice ends up billing for 2 separate programs on the same patient, adding real revenue without increasing your staff's workload. The clinical insight comes from the daily vitals RPM feeds in, giving your care team real numbers to act on between the check-ins APCM or CCM already have built in.

Frequently Asked Questions (FAQs)

Let's close our discussion with answers to some of the questions providers and billers ask often during APCM vs. CCM comparisons:

Is APCM a Medicare Program?

Yes, APCM is a Medicare program. CMS created it through the 2025 Physician Fee Schedule, paying primary care practices, FQHCs, and RHCs a flat monthly rate for ongoing care coordination.

Some Medicare Advantage plans offer similar coverage, though specific rules vary by plan.

What Are the Main Benefits of APCM?

With APCM, you can expect major benefits like predictable monthly revenue and lighter administrative work compared to time-tracked programs.

Reimbursement is also available to every Medicare patient who consents, extending beyond CCM's 2-or-more-condition requirement.

As such, even a patient who's generally healthy still gets a practice actively watching their care between visits, which helps catch small issues before they become problematic. Your team gets a structured framework for risk stratification and proactive outreach.

Can FQHCs and RHCs Bill for APCM?

Yes, you can bill for APCM as an FQHC or RHC.

Both facility types became eligible when CMS introduced the program in 2025. APCM doesn't ask the facilities to track minutes the way CCM does, and it doesn't depend on the retired G0511 code either.

What Happened to Code G0511 for FQHCs and RHCs?

CMS retired G0511, the bundled care management code these facilities relied on since 2018.

After a transition period ending in late 2025, FQHCs and RHCs now bill individual codes for CCM, APCM, and related programs. You can see what changed in greater detail in our breakdown of the 2026 Medicare updates.

Is APCM Replacing CCM?

No, APCM isn't replacing CCM. The 2 programs serve overlapping patient populations.
Many practices ensure both are available and assign patients based on complexity and consent status. CMS built APCM as an additional option for billing coordination work.

Can You Bill APCM and CCM in the Same Month?

No, you cannot bill APCM and CCM for the same patient in the same calendar month. CMS treats CCM, Principal Care Management, and Transitional Care Management as work already bundled into the APCM payment, so submitting both triggers a denial or a clawback.

You can, however, switch a patient between APCM and CCM from one month to the next.

What Is the Difference Between PCM and CCM?

A PCM program covers a single, high-risk chronic condition that needs focused disease-specific management, while CCM covers 2 or more chronic conditions managed together.

In a PCM vs. CCM decision, PCM is often the better fit for specialists managing one complex diagnosis, and CCM fits primary care teams coordinating a patient's full chronic condition list. Like CCM, PCM cannot be billed in the same month as APCM for the same patient.

What Are the APCM and CCM Billing Codes?

APCM bills under 3 HCPCS codes: G0556 for patients with 0-1 chronic conditions, G0557 for 2 or more, and G0558 for patients with 2 or more conditions who also hold QMB status.

CCM bills under CPT 99490 for the first 20 minutes of clinical staff time, 99439 for each additional 20 minutes, and 99491 with add-on 99437 when a physician personally provides the time.

Who Can Bill for APCM?

APCM billing is limited to practitioners who serve as the patient's continuing primary care contact, which in practice means family medicine, internal medicine, and geriatrics clinicians, along with FQHCs and RHCs.

Specialists who don't hold the primary care relationship bill CCM or a PCM program instead.

How Much Does APCM Reimburse per Patient per Month?

APCM rates run from roughly $15 per patient per month at Level 1 to over $100 at Level 3, before geographic adjustment.

Because the amount varies by Medicare Administrative Contractor locality and payment model participation, confirm your own rate in the current CMS Physician Fee Schedule Lookup tool rather than budgeting off national averages.

Does APCM Require Time Tracking?

No, APCM does not require minute tracking. Instead of logging clinical staff time, your practice documents that the 13 required service elements were available to the patient during the month.

CCM works the opposite way: every code is tied to a specific number of minutes that must be logged to support the claim.

Do Patients Need to Consent to APCM and CCM?

Yes, both programs require documented patient consent, and the consent does not carry over between them. A patient who has already consented to CCM or Remote Patient Monitoring must give separate consent before you bill APCM.

Your team also has to explain that standard deductibles, copays, and coinsurance may apply, except for QMB patients at APCM Level 3.

Can You Bill CCM and RPM in the Same Month?

Yes, CCM and Remote Patient Monitoring can be billed for the same patient in the same month.

RPM pays for device-based physiological data rather than care coordination time, so it sits outside the overlap restriction that applies among APCM, CCM, PCM, and TCM. The same holds for pairing RPM with APCM.

Conclusion

Both APCM and CCM reimburse for care coordination work, with the main difference being that they use different rules for clinical time and patient consent.

The right option in a given situation depends on your practice type and patient mix, which explains why many organizations keep both available and open across their patient panel.

Either way, you don't have to shoulder the operational change alone.

KangarooHealth handles the moving pieces for you, from automated time tracking to audit-ready documentation. Additionally, our multilingual clinical team means patients who'd otherwise struggle with English-only outreach get communication they can actually understand and follow, and providers we work with report faster resolution of care alerts as a result.
