You are perhaps thinking of the HITECH Act of 2009? The Obama administration didn't directly fund any open-source healthcare software. There were billions in federal grant funding available to provider organizations to purchase EHR software that met certification criteria for a certain level of interoperability and clinical functionality. This really accelerated the growth of commercial EHR vendors like Epic, as well as some smaller vendors that used FOSS within their offerings.
