Mental & Behavioral Health Billing Audit & Compliance Defense
Defend CPT 90837 60-minute therapy claims against aggressive health insurer clawbacks, resolve telemedicine Modifier 95/POS rejections, and capture psychiatric E/M add-on revenues.
Commercial payers (especially Optum/UnitedBehavioralHealth, Magellan, and Blue Cross) subject mental health and psychiatric providers to intense scrutiny. The primary target is CPT 90837 (60-minute individual psychotherapy). Insurers routinely demand clinical notes to dispute medical necessity, claim session start and stop times were not exact, or attempt retrospective recoupments under Special Investigation Unit (SIU) audits. Our forensic behavioral health audit standardizes session documentation, protects your 90837 utilization rate, and secures full reimbursement for add-on psychiatric evaluations.
Audit red flags
- Payers automatically downcoding CPT 90837 to 90834 because session stop time was not explicitly written in progress note.
- Telehealth therapy claims rejected with CARC 58 due to incorrect Place of Service (POS 02 vs POS 10) or missing FQ/95 modifier.
- Insurers demanding full refunds for 12 months of claims alleging "lack of measurable treatment goals" in DSM-5 diagnostic notes.
- Failure to bill E/M add-on psychotherapy codes (90833) when psychiatrists perform medication management alongside psychotherapy.

Frequently asked questions
Can an insurance company claw back payments for CPT 90837?
Yes, commercial payers frequently initiate prepayment reviews or post-payment audits if a therapist bills 90837 for more than 75% of their total claims. They examine whether notes prove acute symptoms and verify that session duration reached at least 53 full minutes.
How does the Mental Health Parity Act help overturn denials?
MHPAEA prohibits commercial health plans from applying more restrictive Non-Quantitative Treatment Limitations (NQTLs)—such as prior authorizations or session caps—to behavioral health benefits than to medical/surgical benefits.
