About 99439: Additional 20 minutes of staff chronic care management
Report this add-on for each additional 20 minutes of clinical staff chronic care management in a calendar month beyond the initial time reported with 99490.
This service captures additional clinical staff time spent on chronic care management (CCM) for a patient with at least two chronic conditions expected to last at least 12 months or until death and posing a significant risk of death, acute exacerbation, or functional decline. Nurses, medical assistants, and care coordinators working under a physician or other qualified health care professional may perform the work. Activities include phone outreach, medication follow-up, coordination with pharmacies, specialists, and home health, and monitoring a comprehensive care plan. Primary care and internal medicine offices commonly furnish these services.
Report 99439 with 99490 when at least 40 minutes of qualifying time is documented for the calendar month: the initial 20 minutes for 99490 and a full additional 20 minutes for 99439. Medicare permits up to two units of 99439 per month. As an add-on, 99439 is billed with its primary service and paid within that service’s global period. Documentation should support patient consent, the care plan, qualifying activities, and cumulative time. Do not report it with complex CCM codes 99487 or 99489 for the same patient in the same month.
