The federal government — which earlier this month launched a preliminary investigation of the flatlined Cover Oregon health information exchange — on Tuesday released subpoenas that, according to an ABC news report, include demands for communications among the former head of Oregon’s Health Authority, former Cover Oregon executive director, former Cover Oregon CIO, and former Health Authority CIO Carolyn Lawson, who previously held technology positions in California state government, including CIO for the California PUC. At issue is whether Oregon misled federal officials on Cover Oregon’s status.
