Summary
Michigan Medicaid now requires prior authorization for all co-treatment therapy services (PT, OT, SLP working together) effective October 1, 2022. Each therapist must submit separate PA requests using form MSA-115, and billing can be split between therapists or handled by one therapist for the entire session.
Action Required
Before October 1, 2022: Therapy billing staff must implement prior authorization requirements for all co-treatment therapy sessions involving PT, OT, or SLP. Each therapist must submit separate MSA-115 forms simultaneously. Update billing workflows to ensure co-treatment sessions are at least 38 minutes for combined billing. Train staff on splitting billing units between therapists while ensuring combined units don't exceed total treatment time.
