Home and Community Based Services (HCBS) are Medicaid funded services that support independence, person-centered care, and connection to community for disabled people enrolled in Medicaid. With drastic Medicaid cuts on the horizon due to the 2025 Budget Reconciliation Bill, HCBS will likely be impacted. Our objective was to describe HCBS use by service type category among all adults enrolled in Medicaid with intellectual and developmental disabilities (IDD) diagnoses in 2022. We evaluated differences by state, IDD type, and race and ethnicity. We used Medicaid data from all adult enrollees with claims for autism, intellectual disability and Down syndrome and identified HCBS use using established algorithms. Of 1,519,852 adults with IDD, 63.1% (N=958,437) received any HCBS in 2022. The most used HCBS types were case management (32.5%), home based services (32.0%) and non-medical transportation (18.2%). There were limited differences by race and ethnicity, even after adjustment by state. With large Medicaid cuts forthcoming HCBS are optional services that are not mandated to be covered and a possible area for cuts that will disproportionately harm the IDD community.
