U.S. Department of Health and Human Services (HHS), through its Office for Civil Rights (OCR) and the Substance Abuse and Mental Health Services Administration (SAMHSA), finalized modifications to the Confidentiality of Substance Use Disorder (SUD) Patient Records regulations at 42 CFR part 2 (“Part 2”), which protect the privacy of patients’ SUD treatment records. Specifically, the final rule increases coordination among providers treating patients for SUDs, strengthens confidentiality protections through civil enforcement, and enhances integration of behavioral health information with other medical records to improve patient health outcomes.
