CPT 90832 Psychotherapy 30 Minutes Billing

Overview

CPT 90832 is the shortest standard psychotherapy code, covering 16 to 37 minutes of direct face-to-face individual psychotherapy. Used for brief sessions, crisis follow-ups, and medication check-ins. Most payers reimburse CPT 90832 at 50-60% of the 90837 rate. Time documentation is required for all submissions. Sessions under 16 minutes should not be billed as individual psychotherapy.

Coding Rules

CPT 90832 requires minimum 16 minutes of direct patient contact. Sessions under 16 minutes are not billable psychotherapy. If a session runs 38 minutes or longer, use 90834 or 90837 instead. Do not bill multiple brief sessions as a single 90832 code on the same date. Document actual time to the minute. Administrative or documentation time not spent with the patient does not count toward session length.

Prior Authorization & Limits

Prior authorization requirements vary. Some payers require auth for all therapy billing; others require auth only after initial sessions. Session limits typically apply (20-30 sessions annually). Some payers bundle brief sessions (90832) under a different limit than longer sessions. Medicare covers medically necessary therapy without session caps. Always verify payer-specific policies before billing.

Bundling & Modifier Rules

Use modifier 25 if an E/M service is billed on the same day. Modifier 95 indicates telehealth delivery. Modifier 93 indicates audio-only sessions where allowed. Do not bill psychiatric evaluation codes on the same date without modifier 25 on the E/M component. Therapy codes do not require modifier 59 for separate procedure identification.

Documentation Requirements

Document exact start and stop times (e.g., "2:00 PM - 2:25 PM"). Note therapeutic approach and specific interventions, patient mental status and presentation, clinical progress, and any safety concerns. Time documentation is critical; missing or inaccurate time is the primary denial reason.
