CPT 99490: CCM Requirements and 2026 Medicare Rate

CPT 99490 is the base code for chronic care management (CCM): the first 20 minutes of clinical staff time spent each calendar month managing a patient with multiple chronic conditions, under the general supervision of the billing practitioner. In 2026 it pays $66.13 nationally in the non facility setting, before geographic adjustment. It is billable once per month per patient, and only one practitioner can bill CCM for a given patient in a given month.

Which patients qualify

Medicare’s criteria, from the CMS chronic care management booklet (MLN909188): the patient has two or more chronic conditions expected to last at least 12 months or until the death of the patient, and those conditions place the patient at significant risk of death, acute exacerbation or decompensation, or functional decline. Common examples in a primary care panel include diabetes, hypertension, COPD, heart failure, arthritis, and depression, but any conditions meeting the duration and risk test qualify.

What 99490 requires every month

At least 20 minutes of clinical staff time on care management activities in the calendar month, directed by the billing practitioner
A patient centered, electronic comprehensive care plan that is created, monitored, and revised over time
Documented patient consent before the first billing month, verbal or written, covering cost sharing, the one practitioner per month rule, and the right to stop at any time
24/7 access for urgent needs, plus continuity with a designated member of the care team
Core patient data (demographics, problems, medications, allergies) recorded in certified EHR technology

New patients, and patients not seen within the previous year, also need an initiating visit: a face to face E/M visit (99212 through 99215), annual wellness visit, or IPPE where CCM was actually discussed. That visit bills separately from CCM itself.

Who can bill it

Physicians, nurse practitioners, physician assistants, clinical nurse specialists, and certified nurse midwives. The 20 minutes is clinical staff time billed incident to the practitioner under general supervision, which means the staff do the monthly work and the practitioner directs it without needing to be physically present. Time the practitioner spends personally counts too, but if the practitioner is doing most of the work personally, CPT 99491 usually fits better and pays more.

Limits and same month rules

The CMS medically unlikely edit for 99490 is 1 unit per date of service. If the month’s time reaches 40 minutes, add CPT 99439 for each additional 20 minutes, capped at 2 units. In the same calendar month, 99490 cannot be billed alongside complex CCM (99487, 99489) or physician time CCM (99491), and the same practitioner cannot also bill principal care management for that patient. It also cannot be billed in a month with home health supervision (G0181), hospice supervision (G0182), or certain ESRD codes. Remote monitoring can run alongside CCM, but only one of RPM or RTM, not both.

Common errors that cost practices the code

The failures we see are rarely about eligibility. They are operational: time logged as a flat estimate instead of actual minutes, care plans created once and never revised, consent conversations that happened but were never documented, and months where 19 minutes of real work went unbilled because nobody tracked the last minute. A program built on real time logs and a monthly close checklist avoids all four.

One more thing worth knowing: the CY 2027 proposed rule that would require remote monitoring staff to be practice employees does not touch CCM. Outsourced CCM staffing remains permitted under current rules. We wrote a plain language breakdown of what that proposal actually covers.
