Psychiatry & Behavioral Health Billing & Compliance Audit
Recover denied psychotherapy add-on codes (90833), safeguard extended therapy billing (90837) against post-payment audits, and eliminate telehealth parity rejections.
Behavioral health practices face intense audit scrutiny regarding exact time-based documentation. Commercial payers routinely audit CPT 90837 (60-minute individual psychotherapy) and aggressively deny CPT 90833 (psychotherapy add-on billed with medical evaluation and management like 99213 or 99214). Missing exact start and stop times, lack of therapeutic modality documentation, or improper use of incident-to billing for psychiatric nurse practitioners (PMHNPs) can trigger clawbacks reaching hundreds of thousands of dollars.
Audit red flags
- Progress notes documenting "45-minute session" without explicit time-stamped start and stop times (e.g., 10:02 AM - 10:48 AM).
- Psychiatrists billing only 99213 medication management and neglecting billable 90833 psychotherapy add-ons.
- Use of generic phrase templates without documenting patient response to interventions and therapeutic modalities.
- Telehealth claims billed without appropriate place of service (POS 02 or POS 10) and Modifier 95.
Audit action plan
- 1. Time Documentation Audit — Review 100 consecutive psychotherapy encounters to ensure strict compliance with CMS 16-minute interval threshold rules.
- 2. E/M + Psychotherapy Separation Protocol — Implement structured clinical EHR templates separating somatic medication management from insight-oriented or cognitive behavioral psychotherapy notes.
- 3. Payer Parity Act Enforcement — Deploy Mental Health Parity and Addiction Equity Act (MHPAEA) appeals against commercial insurers applying quantitative treatment limits.

Frequently asked questions
What is required to bill CPT 90833 with 99214?
You must document two distinct services: (1) An E/M encounter detailing medical decision making or time spent on medication management, and (2) At least 16 minutes of documented psychotherapy with start/stop times and specific therapeutic techniques used.
Can non-physician therapists bill under a psychiatrist incident-to?
Generally no for psychotherapy codes. Psychotherapy is a direct professional service that must be billed under the clinician’s own NPI. Incident-to rules apply strictly to medical support tasks under direct physician supervision.
