What is CPT Code 99439?

CPT 99439 is defined as: Chronic care management services, each additional 20 minutes of clinical staff time directed by a physician or other qualified health care professional, per calendar month, with the following required elements: multiple (two or more) chronic conditions expected to last at least 12 months, or until the death of the patient; chronic conditions place the patient at significant risk of death, acute exacerbation/decompensation, or functional decline; establishment, implementation, revision, or monitoring of a comprehensive care plan. List separately in addition to code for primary procedure.

This code is primarily used for CCM services. It falls under the category of Care Management / CCM and is valid for the 2026 calendar year according to the CMS Physician Fee Schedule.
