CPT Code 90785: Interactive Complexity Add-On for Psychotherapy

It can be used with group therapy if the session meets the interactive complexity criteria and is billed alongside an appropriate primary psychotherapy code, like 90853 for group therapy.

CPT 90785 is appropriate for interpreter services when the presence of an interpreter significantly complicates communication, requiring additional effort from the therapist during the session.

Medicare does cover CPT 90785, but it must be billed as an add-on code with a primary psychotherapy service code, and documentation must support the interactive complexity factors; coverage policies may vary by Medicare Administrative Contractor, so verifying local Medicare guidelines is recommended.
