Mental and Behavioral Health Billing Services
Mental and behavioral health billing aligned with parity laws, telehealth guidelines and behavioral health code sets for therapy and psychiatry.
What Behavioral Health Billing Has to Track
Behavioral health billing is driven by session duration, service type and authorization limits, with parity rules affecting how plans may restrict coverage. Time documented in the note determines which code is billable.
- Session duration documented to support the code billed
- Medication management separated from psychotherapy services
- Authorization limits tracked across the treatment period
- Telehealth delivery billed under each payer's current rules
Mental and Behavioral Health Billing Explained
Mental and behavioral health billing requires familiarity with therapy add-on codes, psychiatry E/M coding services, telehealth billing rules, and Mental Health Parity and Addiction Equity Act compliance requirements that differ from general medical billing. Psychotherapy codes are time-based and require documentation of session duration, while medication management uses E/M codes with or without psychotherapy add-ons. Applied behaviour analysis follows a separate authorization-driven model, covered under ABA therapy billing.
Medsure RCS manages Florida medical billing services for behavioral health therapists, psychologists, psychiatrists, and licensed clinical social workers across Florida. We apply the correct code combinations for each provider type, handle telehealth billing under current CMS telehealth policies, and ensure parity compliance in claims submission. Mental and behavioral health is part of our specialty medical billing program. Our telehealth billing guide covers virtual care rules, and our psychiatry billing page addresses psychiatric-specific codes.
How It Works: Step by Step
Provider Type and License Verification
Billing rules vary by provider type. We confirm each clinician's license type (LCSW, psychologist, psychiatrist, ARNP) to apply the correct code set and payer enrollment requirements.
Session Duration and Code Assignment
Psychotherapy codes (90832-90838) are assigned based on documented session duration in minutes. The correct time bracket is applied with or without E/M add-on based on the type of service.
Telehealth Modifier Application
Telehealth behavioral health services are billed with correct place of service codes (02 or 10) and modifiers per payer-specific telehealth policies and current CMS guidance.
Parity Compliance Review
Claims are reviewed to ensure behavioral health services are not subject to discriminatory coverage limits compared to medical and surgical benefits under applicable parity requirements.
Why This Matters for Your Revenue Cycle
Time-based code validation and telehealth modifier accuracy drive first-pass acceptance above 95% for behavioral health claims.
All current telehealth billing rules for behavioral health are applied per payer, including post-COVID permanent coverage expansions.
Session notes received by end of day are coded and submitted within 48 hours to minimize reimbursement cycle time.
Billing support for psychiatrists, psychologists, LCSWs, LMHCs, ARNPs, and collaborative care programs.
Common Mistakes in Mental and Behavioral Health Billing
Wrong Psychotherapy Time Bracket
Psychotherapy codes cover specific session duration ranges (16-37 minutes for 90832, 38-52 minutes for 90834, 53+ minutes for 90837). Billing the wrong bracket based on undocumented session time creates medical record discrepancies and audit exposure.
Billing Psychotherapy and E/M on Same Day Without Add-On Code
When a psychiatrist provides both medication management and psychotherapy in the same session, the correct approach is an E/M code (99213-99215) plus a psychotherapy add-on (90833, 90836, or 90838). Billing them as two separate standalone codes is incorrect.
Incorrect Telehealth Place of Service
Telehealth behavioral health services require correct place of service coding. CMS uses POS 02 for telehealth in a facility and POS 10 for telehealth in the patient's home. Submitting the wrong POS code results in claim denials or incorrect reimbursement.
Non-Covered Provider Type Billing
Not all payers cover behavioral health services from all license types. LMHCs may not be covered under Medicare, and certain Medicaid managed care plans restrict covered provider types. Billing a non-covered provider type results in denial.

Mental and Behavioral Health Billing, Frequently Asked Questions
No. Evaluation and management codes are restricted to physicians and, in some circumstances, nurse practitioners and physician assistants with prescribing authority. LCSWs, LMHCs, and psychologists use psychotherapy codes (90832-90837) and psychological testing codes, not E/M codes.
Medicare permanently extended many telehealth behavioral health flexibilities following the public health emergency. Services must be billed with POS 02 or POS 10, and the originating site rules for behavioral health differ from other telehealth. We apply current CMS guidance as of the claim date.
A 90-minute individual psychotherapy session is billed as 90837 plus a second 90837 add-on code for extended time, or as a crisis code if applicable. Two separate 45-minute sessions with the same patient on the same day each require independent documentation and are billed as separate services.
Yes. Group psychotherapy is billed with code 90853 per patient per session. Interactive group therapy uses 90857. Each patient in the group receives a separate claim. Documentation must support group composition, duration, and the therapist's direct participation.
