When you move out of state, your Original Medicare Part A and Part B coverage follows you anywhere in the United States. You simply need to update your address with Social Security Administration to ensure proper billing and communication. However, if you have a Medicare Advantage plan, moving becomes more complex since these plans operate within specific service areas. You’ll likely need to switch to a new Medicare Advantage plan available in your new location or return to Original Medicare. Moving qualifies you for a Special Enrollment Period, giving you 63 days from your move date to make changes. Medicare Supplement policies present another consideration, as insurers may have different underwriting rules in your new state, though your current policy typically remains valid. Prescription drug coverage through Part D plans also have service areas, so you may need to select a new plan in your new location. Contact a Medicare expert before moving to review your options and ensure continuous coverage without gaps or penalties.
