Occupational Therapy Licensure Compact

Current understanding

Michigan HB 4103 (103rd Legislature) would amend the Public Health Code (1978 PA 368) by adding sec. 16188 to enact the Occupational Therapy Licensure Compact, allowing occupational therapists licensed in a member state to practice across state lines under a shared privilege framework. The bill is tie-barred to HB 4104’25 and has passed a chamber. It parallels similar interstate compact efforts for other Michigan-licensed health professions.
