42 CFR Part II: Patients are protected by the Health Insurance Portability and Accessibility Act (HIPAA), but those who are in addiction treatment programs are also covered by 42 CFR Part 2. The goal of Part 2 is to protect patients enrolled in SUD treatment programs from adverse consequences, specifically related to issues such as child custody, divorce, employment, or other criminal or domestic proceedings. It covers the circumstances where patient records can be released to protect the confidentiality of patient records.
