Under HIPAA, HHS has the authority to modify the privacy standards as the Secretary may deem appropriate. However, a standard can be modified only once in a 12-month period.

As a general rule, future modifications to the Privacy Rule must be made in accordance with the Administrative Procedure Act (APA). HHS will comply with the APA by publishing proposed rule changes, if any, in the Federal Register through a Notice of Proposed Rulemaking and will invite comment from the public. After reviewing and addressing those comments, HHS will issue a modified final rule.
