42 CFR Part 2
Confidentiality of Substance Use Disorder Patient Records (US)
42 CFR Part 2 is the US federal regulation that gives records of federally assisted substance use disorder treatment programmes stricter confidentiality protection than HIPAA.
Disclosure generally needs patient consent; a 2024 final rule aligned it more closely with HIPAA, allowing a single consent for treatment, payment and operations, which systems often track with data segmentation labels.
