CPT 99491: Complex CCM — First 30 Minutes (Physician).
CPT 99491 covers complex chronic care management services requiring substantial direct involvement by a physician or qualified healthcare professional (not clinical staff). It reimburses the first 30 minutes of physician/QHP personal time per calendar month for patients with two or more chronic conditions expected to last at least 12 months. Unlike standard CCM (99490), 99491 requires the physician to personally perform the care management activities and make complex medical decisions.

Scenarios
Common billing scenarios.
Physician manages complex multi-condition patient
BillableA physician personally spends 35 minutes during the month reviewing labs, adjusting four medications, coordinating with a cardiologist and nephrologist, and calling the patient about treatment changes for their CHF, CKD stage 4, and diabetes. The complexity justifies 99491 over 99490.
Clinical staff performs the 30 minutes of care coordination
Not BillableAn RN care coordinator spends 30 minutes on care coordination for a complex patient. Even though the patient qualifies for complex CCM, the time was performed by clinical staff, not the physician. Bill 99490 (clinical staff time) instead of 99491.
Complex CCM with add-on time (99491 + 99437)
BillableA physician spends 65 minutes personally managing a patient with five interacting chronic conditions requiring medication reconciliation across three specialists. Bill 99491 for the first 30 minutes and 99437 for the additional 35 minutes.
Billing both 99490 and 99491 in the same month
Not BillableA practice attempts to bill both 99490 (standard CCM) and 99491 (complex CCM) for the same patient in the same month. These codes are mutually exclusive — choose one based on whether the physician or clinical staff performed the care management.
FAQ
Common questions about CPT 99491.
What is CPT 99491?
CPT 99491 is the Medicare billing code for Complex Chronic Care Management, covering the first 30 minutes of physician or qualified healthcare professional (QHP) personal time per calendar month. Unlike standard CCM (99490), it requires the physician to directly perform the care management rather than delegating to clinical staff. It reimburses approximately $86 per month under the 2026 Medicare fee schedule.
How much does CPT 99491 reimburse in 2026?
CPT 99491 reimburses approximately $86 per patient per month under the 2026 Medicare Physician Fee Schedule. This is roughly $24 more per month than standard CCM (99490 at ~$62), reflecting the higher medical decision-making complexity and the requirement for physician personal time rather than clinical staff time.
What is the difference between 99490 and 99491?
The key differences are who performs the work and the time requirement. CPT 99490 requires 20 minutes of clinical staff time under physician supervision. CPT 99491 requires 30 minutes of the physician's own time for complex medical decision-making. Bill 99491 when the patient's conditions are complex enough to require direct physician involvement, not just staff-level coordination.
When should I bill 99491 instead of 99490?
Bill 99491 when the patient's chronic conditions are medically complex enough to require the physician to personally perform the care management — such as managing multiple interacting conditions, complex polypharmacy, or coordinating across multiple specialists. If care coordination can be appropriately handled by clinical staff under supervision, 99490 is the correct code.
Can clinical staff time count toward 99491?
No. CPT 99491 specifically requires physician or QHP personal time. Clinical staff time (RN, MA, care coordinator) does not count toward the 30-minute requirement for 99491. If the care management is primarily performed by clinical staff, bill 99490 instead. The physician must document their personal involvement in the complex care management activities.
What is the add-on code for additional 99491 time?
CPT 99437 is the add-on code for 99491, covering each additional 30 minutes of physician/QHP personal time for complex CCM. It reimburses approximately $63 per unit. Combined with the base 99491, a physician who spends 60+ minutes on complex care management can bill 99491 + 99437 for approximately $149 per patient per month.
