Which code pair best matches the case study description of a patient with dissociative identity disorder receiving psychoanalysis?

• A. F44.81, 90846
• B. F44.81, 90832
• C. F44.81, 90845
• D. F44.89, 90837

Answer: (C)

Matching the clinical diagnosis with the appropriate psychotherapy code is what's being tested here. Dissociative identity disorder is coded F44.81. When the description specifies psychoanalysis as the treatment, the corresponding CPT code is 90845. This code specifically denotes psychoanalytic psychotherapy, which reflects a longer, more intensive approach compared to standard psychotherapy or family therapy. The other options describe shorter or different modalities: 90832 is a 30-minute psychotherapy session, 90837 is a longer individual psychotherapy session but not psychoanalysis, and 90846 is family psychotherapy without the patient present. Therefore, the best pairing is F44.81 with 90845.
