CPT Codes for Psychology Services

Current Procedural Terminology (CPT codes) are used by psychologists and other mental health professionals in order to bill their services to an insurance company or Medicaid. This is not a complete list, but simply a list of some of the most commonly used CPT codes in mental health and psychology services, meant as a quick-reference sheet. It has been updated for the most recent and relevant code changes.

This list is kept updated based upon new codes. However, billing codes generally don’t change very often, so you can usually be assured that the code you’ve been using is correct.

A “facility” in the text below refers only to a hospital, surgical center, or skilled nursing facility. If you’re not providing services in one of those kinds of locations, you should use the “non-facility” coding. Most psychologists and therapists should use the “non-facility” coding, unless they are working in a hospital or related facility.

Most traditional face-to-face, individual psychotherapy sessions should be billed only for 45 minutes (90834). Get to know this code, it is your friend. Most mental health clinicians and therapists should use code 90791 for billing for an intake interview and 90847 for family therapy.

The individual clinician is always responsible for ensuring they are using the most accurate and appropriate CPT billing code when billing for services provided, regardless of who does the actual billing on the clinician’s behalf. Please ensure you understand and bill for the correct CPT code for the services provided to your patient.

Notes: Small type denotes medical payment codes. Facility: Includes hospitals (inpatient, outpatient, and emergency department), ambulatory surgical centers (ASCs), and skilled nursing facilities (SNFs). Non-facility: everything else.
