Specifications include, but are not limited to:. The Department of Social Services has requested extension of contract C202021001 for the existing FADS system with Truven Health Analytics for the period April 1, 2018 through June 30, 2018. The system and related services are required by the federal Center for Medicare and Medicaid Services (CMS) in administration of states’ Medicare/Medicaid programs; therefore, the DSS must ensure there is an uninterrupted FADS solution in operation. Truven Health Analytics is the only feasible source for the maintenance, support, and related services required by the DSS for the existing Truven FADS system. As a result, this represents a proprietary requirement that meets the criteria as a single feasible source under RSMo 34.044 and the State is pursuing this acquisition as a Single Feasible Source procurement
