Coding ​Guide for ​Outpatient ​Mental ​Health ​Services

Here we will break down and go over the CPT® codes used to report, and receive ​reimbursement for, outpatient mental health services conducted by a mental ​health professional.


These codes are uniform, numerical codes which translate to a service. With ​psychotherapy, these codes are typically describing the amount of time and what ​type of session was performed. You can find more information about this below.

What are CPT®

Codes?

90837?

Common Procedural Terminology is developed and maintained by the AMA ​(American Medical Association), first developed and used in 1966. It offers a ​means of creating a standardized, uniform language to increase accuracy and ​efficiency. They are 5 digit codes, and there are up to 11,163 different codes at ​the time of the AMA 2014 code release.


Fortunately, in outpatient mental health the code set we utilize is MUCH ​smaller. We utilize the codes within the 90785-90899 (Psychiatry Services and ​Procedures), which typically is based on time, who the session is focused on, ​and details of that sort.
