Which United States law is focused on data related to health records and privacy?

The Health Insurance Portability and Accountability Act (HIPAA) requires the U.S. Federal Department of Health and Human Services to publish and enforce regulations pertaining to electronic health records and identifiers between patients, providers, and insurance companies. It is focused on the security controls and confidentiality of medical records, rather than the specific technologies used, so long as they meet the requirements of the regulations.
