IMPORTANT: This report is intended to provide an overview of state-by-state variation in coverage of obesity-related prevention and treatment services for adult Medicaid beneficiaries in the United States. Results presented herein are based on extensive review of publicly available documents and, in a minority of cases, information derived from direct telephone inquiries. Data were collected from November 2016 to July 2017 and may not reflect updated guidelines issued during or after this period. As such, it is possible that actual coverage may differ substantially from that suggested by this report. In some cases, reimbursement for treatment services ordinarily excluded from coverage may be provided for individuals with demonstrated medical necessity. We strongly encourage patients and healthcare providers to contact plans directly to inquire about individual coverage and have included potential points of contact with each state profile to facilitate this process.
