Incarceration affects benefits, and the details matter for reentry. The Social Security Administration explains that no benefits are payable for any month a person is in jail, prison or certain other public institutions. For Social Security retirement and disability benefits, payments are suspended when a person is convicted and sentenced to more than thirty continuous days. For Supplemental Security Income, payments stop while the person is confined; if confinement lasts twelve consecutive months or longer, SSI eligibility is terminated and the person must file a new application after release. That difference between suspension and termination can mean weeks or months without income after release.
SSA notes that some institutions have prerelease agreements with local Social Security offices, which allow SSA to begin processing a claim before release. To restart benefits, SSA asks people to contact it and provide official release documents from the facility. SSA also notes that Medicare Part A continues during imprisonment, and that people whose Medicaid ended while in prison will need to contact their local office to apply again.
In Minnesota, DHS states that Medicaid is currently suspended, not terminated, for enrolled people who are in a jail or prison. Suspension can make it faster to restore coverage on release, but it still depends on accurate information reaching the county or Tribe. DHS has also applied to the federal government for a reentry demonstration that would allow Medical Assistance to cover certain services, such as case management, substance use disorder treatment coordination and a supply of medications, in the period before release at selected prisons and jails. Whether and when it takes effect depends on federal approval, so check the DHS reentry page for current status before describing it to anyone.
Waiver and other disability services generally are not delivered inside jails and prisons, and how a person's services are handled during a stay depends on program rules. Ask your lead agency or DSD policy staff rather than guessing. The practical point for case managers is to ask early: when you learn someone has been booked or sentenced, find out what happens to each of their benefits and services, and start planning for release.
