CPT code 99215 description
Code 99215 represents an existing patient appointment that’s at least 40 minutes in duration. It’s a prescriber code, which means it’s most commonly used by psychiatrists or nurse practitioners.
This is is how the American Medical Association defines 99215 in the official CPT codebook:
CPT code 99215: Existing patient office visit, minimum 40 minutes
Office or other outpatient visit for the evaluation and management of an established patient, which requires a medically appropriate history and/or examination and high level of medical decision making. When using total time on the date of the encounter for code selection, 40 minutes must be met or exceeded.
99215 vs 99205: Existing patient vs. new patient
If you’re treating a new patient, you should use 99205 instead. A new patient is someone you have not seen in the last three years.
It’s important to use the code that most accurately reflects the time you spent with the patient to treat their condition, and ensure that documentation for the session supports the chosen code.
