How do I avoid a Medicare Part D late-enrollment penalty increase when I move to a new area and lose my Part D coverage?
Moving and Medicare Part D · updated Jun 7, 2025
The good news: To avoid the Part D late-enrollment penalty simply enroll in a new Medicare Part D plan (PDP) or Medicare Advantage (MAPD) when you move to your new area or region.
And more good news: When you move outside of your plan's Service Area you automatically qualify for a Special Enrollment Period (SEP) to join a new Medicare prescription drug plan in your new area.
Question: What is a Special Enrollment Period?
Special Enrollment Periods allow you to join or change or drop Medicare plans outside of the annual Open Enrollment Period (AEP) that starts October 15 and continues through December 7. The Medicare Part D Special Enrollment Periods are explained on this site and on this site
More about your Medicare plan's Service Area -- Moving when enrolled in a stand-alone Medicare Part D plan
If you are enrolled in a stand-alone Medicare Part D prescription drug plan, your Service Area will be a state or multi-state region. There are 34 stand-alone Medicare Part D "regions" across the country (here is a link to a list of Medicare Part D Regions). You can see from this list that some of the larger states, such as California are a single Medicare Part D region (Region #32). However, some states such as Pennsylvania and West Virginia are combined into one Medicare Part D region (Region #6). So if you move from West Virginia to Pennsylvania, you will keep your same Medicare Part D coverage and not be granted a Special Enrollment Period since you are still in your Medicare Part D plan's Service Area: CMS Region #6.
More about your Medicare plan's Service Area -- Moving when enrolled in a Medicare Advantage plan (MA or MAPD)
If you are enrolled in a Medicare Advantage plan (with or without drug coverage - MA or MAPD) and move to another county or ZIP Code, you will also be provided a Special Enrollment Period to join a Medicare Part D or Medicare Advantage plan in your new area. You can see all Medicare Advantage plans in a specific Zip Code using our Medicare Advantage Plan Finder (MA-Finder.com/44319) - enter your Zip Code or choose a state abbreviation and then choose the county.
As a note, if you are in a highly-populated area (such as Los Angeles county), you may find that your Service Area is only a partial ZIP Code region. Likewise, if you live in a less-populated area such as Rule New Hampshire, you may find that your Service Area extends to several ZIP Codes or partial-ZIP codes. You can telephone your Medicare Advantage plan to learn more about your plan's Service Area - the telephone number is on your Member ID card.
Question: Can I just join the same Medicare plan in my new area?
Yes, if available. Medicare plan availability varies across the country and you may find that your new area does not have the same Medicare plans as your previous residence. But if available, you can enroll into the same Medicare Part D prescription drug plan (again, if available in your new Region) or you can choose a completely new Medicare Part D plan (that may be more affordable). However, the monthly premiums of Medicare Part D plans may vary State-to-State (or Region-to-Region).
Warning: If you wait to long (beyond the 63 days), you may miss your Special Enrollment Period - and then you also probably will have no possibility of drug coverage until the start of the next calendar year (after choosing a new Medicare plan during the AEP).
Bottom Line: When you move your primary residence to a new Medicare Part D Region, you are granted a
Special Enrollment Period (SEP) that will allow you a certain amount of time to enroll into a new plan. You can see all stand-alone Medicare Part D plans in a specific state using our Medicare Part D Plan Finder (PDP-Finder.com/CA) - just choose your state abbreviation to get started. You can see all Medicare Advantage plans across the country using our Medicare Advantage Plan Finder (MA-Finder.com/44319) - just choose your state and county or enter your ZIP to get started.
