<h1>Health privacy violation alleged after federal release of Medicaid enrollee data to immigration enforcement undermines confidentiality.</h1> Twenty state attorneys general allege federal officials improperly transferred Medicaid enrollee data - including names, addresses, Social Security numbers, immigration status and claims information - to the Department of Homeland Security despite CMS warnings that such disclosure could violate federal privacy and program statutes. The states contend the transfer breaches confidentiality protections under HIPAA, the Social Security Act, and the Privacy Act, and Congress members have demanded that data sharing stop and transferred information be destroyed.
