2025 Medicare Part D Prescription Drug Plans: Overview by CMS Region
As required under the Medicare Modernization Act, the Centers for Medicare and Medicaid Services ("CMS") established geographic regions for the administration of stand-alone Medicare Part D prescription drug plans ("PDPs"). CMS established 34 PDP regions consisting of the 50 states and the District of Columbia, as well as 5 separate PDP Regions for the United States territories.
Please note - Medicare Part D Plans vary in cost and coverage by Region - this means that if you move to a State in a different region during the enrollment year, you may pay a different premium and/or possibly may not have access to the same selection of Medicare Part D plans. If you do move to a new region during the plan year, you are granted a Special Enrollment Period (SEP) and are permitted by CMS to change Medicare Part D plans even if your old plan is available in your new region.
