The Centers for Medicare & Medicaid Services should expedite policy guidance on Medicaid coverage of obesity-related services for children, and consider the need for similar guidance regarding coverage of recommended preventive services for adults, according to a new report by the Government Accountability Office. Many children and adults in the Medicaid program have health conditions, particularly obesity, that could be identified or managed by preventive services, GAO said. Senate Finance Committee Chairman Max Baucus (D-MT) requested the report, which examines the extent to which Medicaid children and adults have certain health conditions and receive certain preventive services.
