Chronic care management pays for tracked clinical staff time: 99490 requires at least 20 minutes per calendar month for a patient with two or more chronic conditions. Advanced Primary Care Management replaces that time tracking with a tiered monthly fee, G0556 at roughly $16, G0557 at roughly $54, and G0558 at roughly $117 per patient per month. You cannot bill both for the same patient in the same month.
Care management has been the most under-adopted legitimate revenue in primary care for a decade, and the reason has always been the same: the documentation burden of counting minutes exceeded what practices could sustain. APCM was built to remove that specific obstacle, which makes 2026 the year the choice between the two models actually matters.
The CCM family
| Code | Service | Requirement |
|---|---|---|
| 99490 | Chronic care management | At least 20 minutes of clinical staff time per calendar month |
| 99439 | CCM add-on | Each additional 20 minutes, up to twice per month |
| 99487 | Complex CCM | At least 60 minutes, with moderate or high complexity decision making |
| 99489 | Complex CCM add-on | Each additional 30 minutes |
| G0506 | Initiating visit add-on | Extensive assessment and care planning beyond the usual initiating visit |
Eligibility for CCM requires two or more chronic conditions expected to last at least twelve months or until death, placing the patient at significant risk of death, acute exacerbation, or functional decline. 99490 and 99487 are alternatives; you cannot bill both in the same month for the same patient.
The APCM alternative
APCM, effective from 1 January 2025, pays a bundled monthly fee tiered by patient complexity rather than by minutes.
| Code | Patient tier | Approximate 2026 monthly rate |
|---|---|---|
| G0556 | Zero or one chronic condition | About $16 |
| G0557 | Two or more chronic conditions | About $54 |
| G0558 | Two or more chronic conditions and Qualified Medicare Beneficiary status | About $117 |
The structural difference is the whole point: APCM has no time threshold. There is no minute counting, no monthly time log, no risk of falling one minute short of a billable month. In exchange, the practice must be capable of delivering thirteen defined service elements, including 24/7 access, continuity of care, comprehensive care management, a patient-centered care plan, care transition coordination, population data analysis, and risk stratification. Not every element must be furnished every month, but the capability must exist.

The rules both models share
- Consent is mandatory and specific. The patient must be told the service is available, that only one practitioner can be paid for it in a calendar month, that they can stop at any time effective at month end, and that cost sharing may apply. Document it.
- An initiating visit is required for new patients and for anyone the billing practitioner has not seen within three years. Qualifying visits include E/M levels 2 through 5 (99212 to 99215), the face-to-face component of transitional care management (99495 or 99496), an annual wellness visit, or an initial preventive physical examination, provided the service is discussed during that visit.
- One practitioner per patient per month. This is the most common source of denials in care management, and it is a coordination problem rather than a coding problem.
- Patient cost sharing applies, which means patients receive a bill for a service they may not remember consenting to. Programs that fail usually fail here, not in billing.
Which to choose
APCM generally wins where the practice manages a broad panel and has never sustained reliable minute tracking. The bundled payment converts an unreliable revenue stream into a predictable one, and the G0558 tier captures dual-eligible complexity that CCM does not recognize as a separate category. APCM also cannot be billed alongside CCM, principal care management, or transitional care management for the same patient in the same month, so the switch is a genuine election rather than an addition.
CCM can still win where a practice already runs disciplined time tracking and regularly exceeds 60 minutes on complex patients, because 99487 with 99489 add-ons can exceed the APCM tiers for that subgroup.
Both can be combined with remote patient monitoring. APCM and RPM are billable together, which is where the larger combined monthly figures in the market come from. New behavioral health add-on codes G0568, G0569, and G0570 arrived for 2026 to layer collaborative care and behavioral health integration onto APCM without time-based rules, which is worth reviewing if you run an integrated program; the related psychiatric codes are covered in mental health CPT codes 2026.
One condition worth knowing before committing: APCM participation carries value-based reporting obligations, including performance reporting on the Value in Primary Care MIPS Value Pathway. This is not a code you switch on in the billing system and forget.
FQHCs, RHCs, and critical access hospitals
FQHCs and RHCs can bill the APCM codes at national non-facility Physician Fee Schedule rates, which is a meaningful improvement over how care management has historically been paid in those settings. They may bill APCM instead of CCM where it simplifies the workflow, but not both for the same patient in the same month. Critical access hospitals can bill APCM by assigning the patient to an outpatient primary care billing practitioner. All standard requirements apply regardless of facility type. The wider mechanics of these settings are in FQHC and RHC billing in 2026.
Why programs fail, and what fixes it
Care management programs rarely fail on eligibility. They fail on enrollment consent that was never documented, on duplicate billing where a specialist also claimed the month, on patient complaints about unexpected cost sharing, and on months that quietly go unbilled because nobody owned the calendar.
The fix is boring and effective: a named owner for monthly enrollment reconciliation, consent captured in a retrievable field rather than a note, and a monthly claim run that reconciles enrolled patients against claims submitted. That reconciliation is standard practice inside clinic and physician group RCM, with denials worked through denial management.

Frequently asked questions
What is CPT 99490 used for?
Chronic care management for a patient with two or more chronic conditions, requiring at least 20 minutes of clinical staff time directed by a physician or qualified health professional per calendar month.
What is the difference between CCM and APCM?
CCM pays for documented clinical staff time above monthly thresholds. APCM pays a bundled monthly fee tiered by patient complexity with no time requirement, in exchange for the practice maintaining thirteen defined service capabilities.
What is the difference between CCM and APCM?
No. APCM cannot be billed concurrently with chronic care management, principal care management, or transitional care management for the same patient in the same calendar month by the same practitioner.
How much does APCM pay in 2026?
Approximately $16 per patient per month for G0556, $54 for G0557, and $117 for G0558, before geographic adjustment. G0558 applies to patients with two or more chronic conditions who are Qualified Medicare Beneficiaries.
Does APCM require patient consent?
Yes. The patient must be informed the service is available, that only one practitioner can be paid per month, that they may stop at any time effective at month end, and that cost sharing may apply.
Can APCM be billed alongside remote patient monitoring?
Yes. APCM and RPM are billable together for the same patient in the same month, which is the combination most practices use to build a meaningful monthly care management revenue stream.
