Behavioral Health & Psychiatry Billing: Time-Based CPT Codes, E/M Add-Ons, and Carve-Outs
Essential billing and coding guidance for psychiatrists, PMHNPs, psychologists, and therapy practices navigating mental health insurance benefits.
Time-Based Psychotherapy Coding Thresholds
Psychotherapy CPT codes are strictly time-based. Documenting exact session duration is critical for supporting 90832 (16–37 minutes), 90834 (38–52 minutes), and 90837 (53+ minutes), as well as psychiatric E/M psychotherapy add-on codes (90833, 90836, 90838).
Identifying Behavioral Health Carve-Outs Before the First Session
Many commercial health plans subcontract mental health and substance use disorder benefits to a separate behavioral health organization (BHO). Verifying whether behavioral health claims route to the medical payer ID or a carve-out payer ID prevents immediate claim rejections.
