HIPAA Enforcement by State Attorneys General
The Department of Health and Human Services’ Office for Civil Rights is the main enforcer of HIPAA compliance; however, state Attorneys General also play a role in enforcing compliance with the Rules of the Health Insurance Portability and Accountability Act (HIPAA). The Health Information Technology for Clinical and Economic Health (HITECH) Act gave state attorneys general the authority to bring civil actions on behalf of state residents who have been impacted by violations of the HIPAA Privacy and Security Rules, and they can obtain damages on behalf of state residents. The Connecticut Attorney General was the first to exercise this right in 2010 against Health Net Inc. for the loss of an unencrypted hard drive containing the electronic protected health information of 1.5 million individuals and for delayed breach notifications. The case was settled for $250,000. The Vermont Attorney General followed suit with a similar action against Health Net in 2011 that was settled for $55,000, and Indiana brought a civil action against Wellpoint Inc. in 2011 that was settled for $100,000....
HHS-OIG Report Highlights Key HHS Cybersecurity Challenges
The U.S. Department of Health and Human Services Office of Inspector General has published its annual report on the Top Management and Performance Challenges Facing HHS to help the department improve the effectiveness and efficiency of its programs. The report highlights some of the cybersecurity challenges faced by HHS, including a lack of standardized governance and controls, which complicates HHS’s preparedness efforts to prevent and respond to cybersecurity threats. The HHS is a large department with disparate organizational approaches to cybersecurity across its various divisions and programs. While the department has taken steps to consolidate cybersecurity functions and improve cybersecurity, HHS-OIG says overall progress is often still dependent on each division and program. In addition, the HHS has an army of contractors, grantees, and other external entities that number in the thousands. Cybersecurity solutions must be implemented within the HHS, but also by each contractor, grantee, and external entity. That makes cybersecurity improvements especially challenging, and...
