Confidentiality of Substance Use Disorder Patient Records

Part 2 makes records identifying a patient as having a substance use disorder diagnosis or treatment in a federally assisted program confidential, allowing disclosure mainly with patient consent or under narrow exceptions and court orders. The 2024 final rule (effective April 16, 2024; compliance Feb. 16, 2026) aligned Part 2 with HIPAA, allowing a single consent for treatment, payment, and operations and adding breach notification and HIPAA-style penalties.
