Mental health billing in Florida has three characteristics that make it distinctly challenging: prior authorization requirements that vary significantly by payer and service type, behavioral health CPT coding that is frequently miscoded or under-coded, and HIPAA enhanced privacy requirements that create additional documentation obligations. This guide covers all three.
Prior Authorization in Florida Behavioral Health — What Each Payer Requires
Florida Medicaid FFS requires prior authorization for most outpatient behavioral health services beyond an initial evaluation. The authorization process is managed through AHCA's prior authorization portal. Florida MMC plans each have their own prior authorization requirements, which often differ from FFS — some require authorization for the initial evaluation, some do not.
- ✓Sunshine Health: requires prior auth for individual therapy sessions beyond 8 per year without concurrent review; concurrent review required for continuation
- ✓Humana Medicaid Florida: prior auth required for all outpatient psychiatric services; uses their own behavioral health prior auth portal
- ✓Florida Medicaid FFS: prior auth through AHCA required for psychiatric testing, ECT, and services beyond initial screening thresholds
- ✓Commercial payers: most require prior auth for ABA therapy, transcranial magnetic stimulation, and intensive outpatient programs; standard outpatient therapy often does not require auth
Behavioral Health CPT Codes — The Most Common Billing Errors
- ✓Billing 90837 (60 min) when session documentation supports only 90834 (45 min) — time-based codes require documented start and end time in the clinical record
- ✓Incorrect use of 90833 (add-on for medication management during psychotherapy) — this code requires both psychotherapy AND medication management in the same session, documented separately
- ✓Billing group therapy codes (90853) for concurrent individual therapy — group therapy requires at least 2 patients present and documented
- ✓Missing modifier for services provided by a supervised clinician — supervisory billing requires specific modifier and documentation of supervision
- ✓Telehealth place of service error — billing 11 (office) instead of 02 (telehealth) or 10 (patient home telehealth) for remote sessions
HIPAA Enhanced Privacy in Mental Health Billing
Mental health records have enhanced HIPAA protections in Florida beyond standard PHI. Psychotherapy notes (as defined under HIPAA) cannot be included in a general medical record release without specific authorization. For billing, this means: EOP (Explanation of Payment) disclosures to patients must be careful about what diagnostic information is included on statements, and certain payer requests for documentation must be carefully reviewed before release.
Prior Authorization Management Workflow for Behavioral Health
- ✓Obtain initial authorization before the first billable session — not before the assessment, before the first treatment session
- ✓Track authorized sessions against sessions delivered in real time — not at month-end
- ✓Set authorization expiration alerts 30 days before expiration to allow time for concurrent review
- ✓Never schedule beyond authorized sessions — scheduling and billing systems must be synchronized on authorization limits
- ✓Document concurrent review submission dates and outcomes in the patient file — payer audit requests for concurrent review documentation are common
