How do CPT codes 90832, 90834, and 90837 differ?

• A. 90832 = 30 minutes; 90834 = 45 minutes; 90837 = 60 minutes; all require documentation of content and whether patient was present.
• B. 90832 = 60 minutes; 90834 = 60 minutes; 90837 = 60 minutes; documentation only.
• C. 90832 = 15 minutes; 90834 = 25 minutes; 90837 = 40 minutes; no documentation required.
• D. 90832 = group therapy; 90834 = family therapy; 90837 = individual therapy

Answer: (A)

These codes are time-based for individual psychotherapy, with the code you choose depending on how long the session lasts. The three durations align with a 30-minute session, a 45-minute session, and a 60-minute session. Using the correct duration lets you bill for the actual time spent with the patient, which is essential for accurate reimbursement and record-keeping.

The reason this option is the best is that it matches the standard CPT definitions for these codes and also requires documenting what was discussed during the session and that the patient was present. This documentation shows the content and presence necessary to justify the specific time-based code used, ensuring proper billing.

The other choices are off for a few reasons: one incorrectly states equal 60-minute lengths for all three, another claims no documentation is required, and another misidentifies the services as group or family therapy rather than individual psychotherapy.
