Medicare Advantage Trial Right Explained: When You Can Return to Medigap

Last Modified: 10/05/2026 | Reviewed by Keith Armbrecht (NPN 634015)

Quick Summary

The Medicare Advantage trial right is a federal protection that can give certain people an opportunity to leave Medicare Advantage, return to Original Medicare, and purchase Medigap without normal medical underwriting barriers.

There are two important trial-right situations.

One applies when you first join Medicare Advantage when becoming eligible for Medicare at age 65 and decide to return to Original Medicare during the first year.

Another can apply when you drop an existing Medigap policy to try Medicare Advantage for the first time and decide within 12 months that you want your Medigap coverage back.

Key Facts

  • The federal trial-right period is generally 12 months.
  • It only applies in specific circumstances.
  • It isn’t a general 12-month right every time you join Medicare Advantage.
  • You must return to Original Medicare.
  • Certain Medigap guaranteed-issue protections apply.
  • Prescription drug coverage needs to be coordinated.
  • Deadlines matter.
  • State laws may provide additional protections.
  • Keep proof of your former Medigap policy and Medicare Advantage enrollment.

Trial Right #1: You Started Medicare With Medicare Advantage

Suppose you become eligible for Medicare at age 65 and choose Medicare Advantage instead of Original Medicare.

If you decide during your first year that you want Original Medicare instead, federal trial-right protections can allow you to buy certain Medigap policies available in your state.

Trial Right #2: You Dropped Medigap to Try Medicare Advantage

Suppose you already had:

Original Medicare + Medigap

and then dropped your Medigap policy to join a Medicare Advantage plan for the first time.

If you decide within the applicable 12-month trial period that you want to return to Original Medicare, you may have the right to get your former Medigap policy back if the same insurer still offers it.

If it isn’t available, other guaranteed-issue options may apply.

Why the Trial Right Matters

Outside protected situations, returning from Medicare Advantage to Medigap can sometimes require:

Medical underwriting

depending on your state.

The trial right can remove that obstacle when its requirements are satisfied.

Don’t Wait Until Month 12

If you think Medicare Advantage isn’t a good fit, begin investigating your rights before the end of the trial period.

You need time to coordinate:

  • Disenrollment from Medicare Advantage
  • Original Medicare
  • Medigap
  • Part D prescription coverage

Keith's Take

This is a Medicare rule more people should know about.

Someone tries Medicare Advantage, realizes they don’t like the network or authorization structure, and assumes they’re stuck forever.

If you’re inside a valid trial-right period, you may have valuable Medigap protections.

But the important words are:

“May have.”

Don’t simply cancel Medicare Advantage.

First determine exactly which trial-right rule applies and which Medigap coverage you can obtain.
