Group psychotherapy is reported with code 90853.
This is not a time-based code: one unit of service should be reported for each group member according to CPT®. Group therapy typically lasts 45 to 50 minutes, and some payers set a limit at 12 participants. Many payers require that the number of members in the group is documented in each individual record.
The documentation for the group psychotherapy should include a summary of the group’s goals and purposes for that day, and that portion of the note may be the same for all participants. It must also include a description in the individual patient’s chart of that patient’s interaction and involvement in the group therapy.
