2026 AEP
The Most Popular Medicare Advantage Plans in Every County — 2026 AEP Results
See exactly which carriers dominate your market. Built from official CMS enrollment data (January 2026), so you're looking at real post-AEP enrollment — not marketing claims.
How to use this tool:
- Search your county — Start typing your county name in the search box (e.g., "Lackawanna, PA") and select it from the list.
- Read the rankings — Carriers are listed by market share: the percentage of all Medicare Advantage enrollees in that county on each carrier's plans.
- Check the state view — Flip to the State Overview tab to see which carriers lead statewide and compare against your county.
- Use these numbers to pick out carriers that are popular in your county / state — High share means name recognition at the kitchen table. Low share plus strong benefits can mean an underserved opportunity. Either way, walk in knowing the landscape.
