Which CPT code corresponds to a 60-minute individual psychotherapy session?

• A. 90832
• B. 90791
• C. 90837
• D. 90834

Answer: (C)

Time-based CPT codes for psychotherapy match the length of the face-to-face session. For a single, ongoing individual psychotherapy visit, the 60-minute option is represented by the code that specifically denotes one hour of psychotherapy time. This code is used when the session lasts about an hour and reflects a full hour of direct therapeutic interaction. The other codes correspond to shorter durations—30 minutes and 45 minutes—used for shorter therapy sessions. A psychiatric diagnostic evaluation code is used when the visit is focused on assessment and diagnosis rather than ongoing psychotherapy. Therefore, the 60-minute individual psychotherapy session is coded with the 60-minute option.
