When you are incarcerated, you should disenroll from your stand-alone prescription drug plan (Part D) or Medicare Advantage Plan. This is because you are ineligible for these plans for the duration of your time in jail, prison, or otherwise in the custody of penal authorities.
When you are released, you have a Special Enrollment Period (SEP) to join a Part D plan or a Medicare Advantage Plan. Your SEP lasts two months, starting the month before you are released. For example, if you are scheduled for release April 1, your SEP is March 1 through April 30. You should choose a plan that works best for your drug and health care needs. You must inform the plan you choose of your address so they can confirm you are in their coverage area and eligible to enroll in that plan.
