Background: Under current law, most Social Security Disability Insurance (SSDI) beneficiaries are not eligible for Medicare until 29 months after the Social Security Administration determines the onset of their disability. During this waiting period, >1 in 5 lacks health insurance. This study investigated the effects of providing health care benefits on the health, employment, and other services of uninsured beneficiaries.
