The HHS, Office for Civil Rights, recently issued guidance that addresses the HIPAA Privacy Rule in light of United States v. Windsor, the 2013 Supreme Court decision that struck down a portion of the Defense of Marriage Act (DOMA) as unconstitutional.  The guidance clarifies that the Privacy Rule covers individuals who are in same-sex marriages.  Specifically, in certain circumstances, covered entities may share individuals’ protected health information with same-sex spouses, and health plans are prohibited from using same-sex spouses’ genetic information for underwriting purposes.
