Medicare Advantage Changes in 2026: Nearly 3 Million People Affected

If you have a Medicare Advantage plan for 2025, here’s the blunt truth: there is a real chance your plan is ending, shifting, or being replaced for 2026. Almost three million people are being moved, dropped, or placed into plans they did not choose.

This is the largest Medicare Advantage shake-up on record.

If you want a closer look at why this is happening, the Medicare Advantage Plans Are Ending in 2026 for Millions: Here’s What to Do guide gives a clear overview.

Key Takeaways

  • Almost 3 million Medicare Advantage members are affected for 2026
  • Four main disruptions: plans ending, leaving counties, merging, or cutting benefits
  • You might lose your plan even if the plan name stays the same
  • Doing nothing can place you back on Original Medicare without drug coverage
  • Action must be taken before December 7
  • Signs you’re affected: letters, plan ID changes, benefit changes, network changes, missing from 2026 listings
  • Brickhouse Agency offers free reviews to help you choose a safe 2026 option

Why This Is Happening in 2026

Plan changes during AEP are normal, but this year is very different.
Some carriers are shrinking, some are merging plans, and others are reducing benefits to maintain pricing.

Behind the scenes, counties are being removed, networks are tightening, and some plans that look the same on the surface are not the same once you read the details.

If you received any letter at all, do not ignore it.
Millions of people learned they were losing their plan only after trying to compare 2026 options.

The Four Ways People Are Losing or Being Moved From Their Plans

1. Your Plan Is Ending

This is the simplest to spot:
Your letter tells you the plan will not exist in 2026.

If you do nothing, Medicare places you back on Original Medicare. That usually means no drug coverage unless you pick a Part D plan—and far higher medical exposure.

If your plan is ending and you want help comparing your next steps, the Losing Your Medicare Advantage Plan for 2026? Here’s How to Choose What’s Next article walks you through the options.

Takeaway: You must pick a new plan.

2. Your Plan Is Leaving Your County

Sometimes the plan still exists ,but not in your ZIP code.
People across the county line may keep it, but you cannot.

Your letter usually says the plan will not be available in your service area.

Takeaway: You need a replacement plan for 2026.

3. Your Plan Changed Behind the Scenes

This one is harder to catch.

A plan can be:

  • merged
  • renamed
  • assigned a new plan ID

If your plan ID changed, the version you had in 2025 is not the same version you’ll have in 2026.

Benefits, networks, and costs may be different even if the name looks familiar.

Takeaway: A new ID means a new plan. Compare carefully.

4. Your Plan Still Exists, but Benefits Were Cut

Maybe the name stayed the same, but inside the plan things shifted:

  • Out-of-pocket limit
  • Drug tiers
  • Copays
  • Network
  • Dental or vision allowances
  • Travel coverage
  • Premium

Millions will feel these changes even though their plan “looks” the same.

Takeaway: Never assume benefits stayed the same just because the name did.

How to Tell If You Are Affected

Here are the clearest warning signs:

  • You received any letters
  • Your plan ID changed
  • Your premiums or copays increased
  • A doctor or hospital is no longer listed
  • Your drug costs changed
  • Your plan is missing from the 2026 plan listings
  • Benefits look thinner
  • Something feels off compared to 2025

If any of these apply, you should review your plan before December 7.

Doing nothing can result in:

  • being moved into a different Medicare Advantage plan you did not pick, or
  • being placed back on Original Medicare without drug coverage

Medicare will not fix this for you.
You must take action.
