Coverage for Obesity Prevention and Treatment Services: Analysis of Medicaid and State Employee Health Insurance Programs.

OBJECTIVE: This study examined changes in coverage for adult obesity treatment services in Medicaid and state employee health insurance programs between 2009 and 2017.

METHODS: Administrative materials from Medicaid and state employee health insurance programs in all 50 states and the District of Columbia were reviewed for indications of coverage and payment policies specific to evidence-based treatment modalities for adults (≥ 21 years of age) with obesity, including nutritional counseling, pharmacotherapy, and bariatric surgery.

RESULTS: From 2009 to 2017, the proportion of state employee programs indicating coverage increased by 75% for nutritional counseling (from 24 to 42 states), 64% for pharmacotherapy (from 14 to 23 states), and 23% for bariatric surgery (from 35 to 43 states). The proportion of Medicaid programs indicating coverage increased by 133% for nutritional counseling (from 9 to 21 states) and 9% for bariatric surgery (from 45 to 49 states), with no net increase for pharmacotherapy (16 states in both plan years).

CONCLUSIONS: Coverage for adult obesity care improved substantially in Medicaid and state employee insurance programs since 2009. However, recommended treatment modalities are still not covered in many states. Where coverage has expanded, educating providers and beneficiaries on the availability and proper use of evidence-based obesity treatments may improve health outcomes.
