Quick Answer
CPT 99490 is billed once per calendar month per eligible patient, covering the first 20 minutes of non-complex chronic care management furnished by clinical staff under a billing practitioner's general supervision. It requires an eligible patient, a prior initiating visit, documented consent, and a comprehensive care plan.
What Is CPT 99490?
CPT 99490 describes clinical staff time — at least 20 minutes per calendar month — spent on chronic care management activities such as care coordination, medication review, and communicating with the patient between office visits. CMS assigns 99490 "general supervision" status under the Physician Fee Schedule, meaning the billing practitioner doesn't need to be personally present while the service is delivered, though it remains under their overall direction and control.
Current Reimbursement Context
The Medicare Physician Fee Schedule sets a national, non-facility payment amount for CPT 99490 that CMS updates at least annually and adjusts by locality (geographic practice cost index). Use the CCM Revenue Calculator below for a configurable estimate, and the CMS Physician Fee Schedule Look-Up Tool linked in Official Resources for the exact, locality-adjusted current figure.
Who Qualifies?
Eligible patients have two or more chronic conditions expected to last at least 12 months, or until the patient's death, that place them at significant risk of death, acute exacerbation or decompensation, or functional decline. See our Medicare CCM Eligibility guide for the full explanation.
General Time/Service Requirements
CPT 99490 requires at least 20 minutes of clinical staff time in the calendar month, directed by the billing practitioner. Time spent by the billing practitioner personally can also count toward this threshold, unless that time is instead being used to report CPT 99491 (which is time personally performed by the billing practitioner and billed differently — see 99490 vs 99439 for the related add-on code).
Patient Consent
Before billing CPT 99490, the billing practitioner must obtain the patient's written or verbal consent and document it in the medical record, including: the availability of CCM services, possible cost-sharing responsibilities, that only one practitioner can furnish and bill CCM in a given calendar month, and the patient's right to stop services at any time (effective at the end of that calendar month). Consent is required only once, unless the patient switches to a different CCM practitioner.
Initiating Visit Considerations
CMS requires an initiating visit before starting CCM for a new patient, or a patient not seen within the previous year. The initiating visit must occur during a comprehensive face-to-face evaluation and management (E/M) visit, an annual wellness visit, or an initial preventive physical exam — CCM cannot be discussed for the first time outside one of those visit types and still count as the initiating visit. The face-to-face visit itself is billed separately from CCM.
What Activities May Count?
Per CMS's CCM service elements, qualifying activities include structured recording of patient health information in a certified EHR, creating and maintaining a comprehensive electronic care plan, managing care transitions (e.g., following up after a hospital or ED discharge), and coordinating and sharing patient health information promptly with other practitioners and, where relevant, home- and community-based service providers.
Documentation Expectations
Documentation should reflect the total qualifying time for the month, the specific care coordination activities performed, the current comprehensive care plan, and evidence that 24/7 access to care and a designated care team member were made available to the patient. Time that's also being used to satisfy another billed code cannot be counted twice toward the CCM threshold.
99490 vs 99439
CPT 99439 is an add-on code for each additional 20 minutes of non-complex CCM in the same month, once the base 20 minutes (99490) is met — it's never billed on its own. See our 99490 vs 99439 comparison for the full breakdown.
99490 vs Complex CCM
Complex CCM (CPT 99487, plus add-on CPT 99489) applies when a patient's care requires at least 60 minutes of clinical staff time per month and moderate- to high-complexity medical decision-making by the billing practitioner — a materially higher bar than 99490's 20-minute, non-complex threshold. CMS billing rules don't allow reporting 99490/99439 and 99487/99489 for the same patient in the same calendar month, so a practice must classify each enrolled patient into one category or the other for that month.
Billing Mistakes to Avoid
- Billing 99490 without a documented initiating visit for a new or lapsed patient
- Missing or undocumented patient consent
- Reporting both non-complex CCM (99490/99439) and complex CCM (99487/99489) for the same patient in the same calendar month — CMS does not allow this
- Double-counting clinical staff time that's also being billed under a different service code
- Billing without an up-to-date comprehensive care plan on file
Example Practice Scenario
Example only, not a real practice. A primary care practice identifies 220 patients with two or more qualifying chronic conditions. After outreach, 110 enroll in CCM. Of those, 80 receive only the base 20-minute service (99490) most months, 22 also receive one additional 20-minute increment (99439), and 8 require complex CCM (99487 plus one 99489 increment). Use the CCM Revenue Calculator below with these same numbers to see the resulting monthly and annual estimate.
