Medicare APCM: how patient communication supports the care plan

Advanced Primary Care Management (APCM) is a Medicare program that pays a primary care practice a monthly amount for each patient whose care it manages. CMS started it on January 1, 2025. Most of what it asks for depends on patient communication: patients must be able to reach the practice at any time, the care plan must reach the patient, and follow-up must happen on time.

This article gives a high-level summary. It is not billing or compliance advice. Use the CMS APCM page and your billing team for current rules.

What APCM is

APCM puts several care management services into one monthly bundle. CMS describes it as a bundle of parts of principal care management, transitional care management, chronic care management, and communication technology-based services. A practice bills once a month for each patient instead of billing each service by the minute.

Some key points:

Who can bill. The physician or practitioner who is responsible for all of the patient's primary care and is the focal point for the patient's care.
Three levels. The level depends on the patient's number of chronic conditions and whether the patient is a Qualified Medicare Beneficiary. All levels require the same service elements.
No time tracking. APCM has no minute thresholds. This is the main difference from chronic care management.
Consent. The patient gives verbal or written consent once, and the practice records it. Cost sharing generally applies, and the patient must be told this.
Behavioral health add-ons. From 2026, optional add-on codes let practices bill behavioral health integration and collaborative care in the same month as APCM.

What APCM asks of the practice

CMS lists the service elements a practice must be able to provide. A practice does not have to provide each element every month, only when it is clinically appropriate. Several of these elements are about communication:

24/7 access and continuity. Patients and caregivers can reach the care team about urgent needs at any time. Each patient has a designated team member for routine appointments.
An electronic care plan. The practice keeps a patient-centered care plan up to date, shares it with the people involved in care, and gives a copy to the patient.
Care transitions. The practice coordinates referrals and follows up after an emergency department visit, a hospital stay, or a skilled nursing stay, within seven days when clinically indicated.
Enhanced communication. Patients have ways to communicate that are not only phone calls, such as secure messages or a portal.
Population-level management. The practice uses its patient data to find care gaps and sort patients by risk.

Where communication supports the care plan

The care plan lives in the EHR. It only helps the patient when it turns into action: a scheduled visit, a filled prescription, a follow-up after discharge, a question answered at the right time. That takes many short conversations, and most practices do not have the staff time for all of them.

AI agents can take on the routine part of these conversations, inside the rules your practice sets.

Access at any hour

An agent answers every call, day and night. It collects the reason for the call, follows your on-call schedule for urgent needs, and writes the call to the EHR so the care team sees it the next morning. Routine requests become a task for the right person. See after-hours medical answering.

Follow-up that happens on time

Care plans depend on follow-up: a visit after a hospital stay, an annual wellness visit, a lab before the next appointment. With patient outreach, your team approves a list of patients and the agent calls and texts them, books the visit or collects the answer, and records each outcome in the EHR. Patients who do not reply go back to staff.

More than one way to reach the practice

Patients can reply by text instead of calling back during office hours. The agent records the message and sends anything that needs a clinical decision to the clinical owner you name.

Closing care gaps

Outreach works best with a list built from your own population data, such as patients who are due for a screening. See care gap outreach.

What stays with the care team

The agent does not decide who is eligible for APCM, does not give clinical advice, and does not bill. Your clinicians own the care plan and every clinical decision. Your staff record consent and handle the exceptions the agent sends to them. The agent does the repetitive contact work so your team can spend its time on the patients who need it.

How to start

Choose one element where your practice has a gap today, for example after-hours access or follow-up after discharge. Measure how many patients you reach now, start one workflow, and compare after a month.
