Preventive services include immunizations, screenings for common chronic and infectious diseases and cancers, clinical and behavioral interventions to manage chronic disease and reduce associated risks, and counseling to support healthy living and self-management of chronic conditions, such as those associated with obesity. A list of preventive health care services recommended as Grade A or B by the U.S. Preventive Services Task Force can be found at: https://www.uspreventiveservicestaskforce.org/uspstf/.
Through Medicaid's children's benefit - Early and Periodic Screening, Diagnostic and Treatment (EPSDT) - children under age 21 enrolled in Medicaid are assured coverage for preventive and comprehensive health services. States cover adult preventive services within Medicaid through both mandatory and optional benefit categories. Some preventive services (such as those related to family planning) may be defined in a state's mandatory set of benefits while others may be included in the optional benefit category. As a result, Medicaid programs differ from state to state on the coverage of preventive services for adults.
Obesity-related services are those services that help prevent and manage unhealthy weight. Medicaid and CHIP programs can cover a range of services to prevent and reduce obesity including Body Mass Index (BMI) screening, education and counseling on nutrition and physical activity, prescription drugs that promote weight loss, and, as appropriate, bariatric surgery.
