What 99437 covers
Code 99437 captures an additional 30 minutes of chronic care management personally performed by a physician or other qualified health care professional during a calendar month. It supports ongoing coordination for a patient with multiple chronic conditions, such as coordinating a medication change with a specialist, updating the care plan, and following up on care transitions. The service is generally part of longitudinal outpatient management rather than a face-to-face visit, and the time must reflect qualifying work performed by the physician or qualified professional, not clinical staff time.
Report 99437 as an add-on to 99491, which accounts for the initial 30 minutes of physician or qualified professional chronic care management in the month. Documentation should identify the chronic care management activities, the responsible professional, and the time supporting each reported increment. Do not use it to count time already reported for another service or to represent staff-delivered chronic care management. CMS classifies it as an add-on code: it must be billed with its primary procedure, and payment is within that procedure's global period.
