Using 100 percent Medicare Part B fee-for-service (FFS) claims in 2012 for people under age 65, I examine office and outpatient services by state and primary diagnosis for the service. The number of services per Medicare-eligible beneficiary in the U.S. Social Security Disability Insurance (SSDI) program was about 32 in 2012, or 2.7 per month, comparable to services for the 65+ Medicare population. The number of services for SSDI beneficiaries ranged from almost 48 per capita in Minnesota to 23 in Arkansas. Services for musculoskeletal impairments averaged 4.6 per capita, ranging from 6.7 in Minnesota to 2.5 in Hawaii. The greatest variation occurred in services for mental disorders, averaging 3.2 for the U.S. but ranging from 9.1 in Massachusetts to 1.4 in Alabama. Factors such as the number of health care professionals or hospital beds per capita, the share enrolled in Medicare Advantage, and demographic factors are associated with health care utilization across states. Knowledge of health care utilization could inform policy choices for programs such as early intervention efforts both at the federal level and tailored to particular needs at the state level.
