Yes — moving to a new permanent address outside your current Medicare Advantage or Part D plan's service area triggers a Special Enrollment Period that lets you switch to a plan available in your new county. The SEP starts the month before you move (if you tell your plan in advance) or the month you notify your plan (if you tell them after), and it lasts two full months after that. Medicare Plan Finder shows every plan approved for your new ZIP code, and Senior Direct Answers publishes the CMS Landscape data for every U.S. county at seniordirectanswers.com/plans.

What it means
- Moving within the same service area may not trigger an SEP — check your plan's service-area map.
- If you do not enroll in a new plan during the SEP, CMS returns you to Original Medicare.
- Notifying the plan on time expands the SEP by one month on the front end.
Action steps
- Notify your current plan of the move as soon as you have the new address.
- Look up plans in your new county on Medicare Plan Finder or at seniordirectanswers.com/plans/{state}/{county}.
- Enroll in the new plan during the SEP; coverage starts the first day of the month after enrollment.
Risks & deadlines
- Missing the 2-month post-move SEP window means waiting until the next AEP (October 15–December 7) or MA-OEP (January 1–March 31).
