Change Medicare Part D Address
Medicare Part D patients will need to call the issuing insurer before the move to make sure the plan will remain valid in the new location. Patients moving across town shouldn't have any problems with the address change, but those moving out of state could lose coverage. Part D members without insurance changes can often change the address online through the issuer's website. For more information, or if you have reason to question your coverage, call Medicare itself at 1-800-633-4227.
