On June 17, 2011, the Centers for Medicare & Medicaid Services (CMS) published a proposed rule that would establish conditions of participation (CoPs) that community mental health centers (CMHCs) must meet to participate in the Medicare program. In issuing the CoPs, CMS seeks to adopt “a client-centered, interdisciplinary approach that recognizes the contributions of various skilled professionals and other support personnel and their interaction with each other to meet the client’s needs.” The rule proposes specific requirements for CMHC services in the areas of: (1) personnel qualifications; (2) client rights; (3) admission, initial evaluation, comprehensive assessment, and discharge or transfer of the client; (4) treatment team, active treatment plan, and coordination of services; (5) quality assessment and performance improvement; and (6) organization, governance, administration of services, and partial hospitalization services. The CoPs would serve as the basis for survey activities for the purpose of determining whether a CMHC meets the specified requirements that are considered necessary to ensure the health and safety of clients. CMS will accept comments on the rule until August 16, 2011.
