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.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
