Psychiatry E/M Coding: Billing E/M with Psychotherapy

Psychiatry is one of the few specialties that regularly bills an evaluation and management (E/M) visit and psychotherapy in the same encounter. Done right, it captures the full value of the visit. Done wrong, it's a reliable source of denials and downcodes.

The two-part visit

A medication-management visit that also includes therapy has two billable components: the E/M service (the medical evaluation and management) and a psychotherapy add-on for the therapy portion. You bill both, but each has its own rules.

Selecting the E/M level

Office E/M codes (99202–99215) are chosen based on medical decision making (MDM) or total time on the date of service. The key trap: when you bill a psychotherapy add-on, the time spent on therapy cannot also count toward time-based E/M selection. Use MDM for the E/M level in that case, or keep the time strictly separated.

The psychotherapy add-on codes

Add-on codes are never billed alone, they accompany the E/M service.

Where psychiatry E/M billing goes wrong

• Double-counting time. Counting therapy time toward a time-based E/M level.
• Weak documentation. Notes that don't clearly separate the E/M work from the psychotherapy.
• Missing the add-on. Billing only the E/M and leaving the therapy revenue on the table.
• Interactive complexity. Forgetting 90785 when it applies.

Getting it right at scale

The safeguard is validating each claim's E/M level, add-on pairing, and documentation before submission, exactly what AI psychiatry billing does, as part of AI behavioral health billing. For the full code list see the behavioral health CPT code guide, and for time-based psychotherapy specifically, 90837 vs 90834.
