Can You Switch From Medicare Advantage To Medigap?

Open door of light beside a sealed frosted-glass door with a prism lock — switching from Medicare Advantage to Medigap and the underwriting barrier

Quick Answer

Switching is allowed during annual enrollment windows, but buying the Medigap policy after the initial 6-month open enrollment window generally requires medical underwriting in Nevada, and insurers can decline or surcharge based on health. First-year Advantage enrollees have limited trial rights.

Leaving Medicare Advantage for Original Medicare is permitted during annual enrollment periods, including October 15 through December 7. The hard part is the Medigap policy that makes Original Medicare affordable. After the 6-month Medigap open enrollment window that starts with Part B, Nevada generally allows insurers to apply medical underwriting, meaning applications can be declined or surcharged based on health history. First-year Advantage enrollees hold limited trial rights that allow a protected return, which makes the first twelve months the safest time to reverse the decision.

The switch involves two doors, and almost everyone only checks the first one. Leaving Advantage is easy. Getting into Medigap afterward is the door that may not open.

Why is the switch harder than it sounds?

Because it’s two separate transactions with opposite rules:

  1. Dropping the Advantage plan — allowed every year during the October 15 to December 7 annual enrollment period. No health questions, guaranteed.
  2. Buying the Medigap policy — after the initial 6-month open enrollment window, Nevada generally allows insurers to apply medical underwriting. Applications can be declined or surcharged based on health history.

Step one always works. Step two works reliably only for the healthy — which is exactly backwards from who wants to switch, since the desire to leave Advantage usually follows a diagnosis or network frustration.

Who gets a protected path back?

First-year Advantage enrollees. Federal trial rights give certain people in their first twelve months on an Advantage plan a guaranteed route back to Medigap without underwriting. The protection is narrow and situation-specific, but real: it effectively makes the first Advantage year a test drive. After that year, the guarantee is gone and underwriting stands between the enrollee and a supplement.

How should the switch risk shape the original decision?

By treating the initial choice as partly a one-way door. Advantage remains purchasable every single year for life; Medigap without health questions is generally available once, in the 6-month window that starts with Part B. Anyone leaning Advantage should decide within the first year whether it truly fits, while trial rights still apply. The full trade-off — costs, networks, travel, and the underwriting door — is mapped in the Advantage versus Medigap comparison for Nevada.

Frequently Asked Questions

Is switching from Advantage to Medigap allowed?

Dropping an Advantage plan for Original Medicare is allowed during annual enrollment windows. The obstacle is the Medigap purchase, which generally requires medical underwriting in Nevada after the initial 6-month window.

What is medical underwriting for Medigap?

Underwriting means the insurer reviews health history before issuing a policy and can decline the application or charge a higher premium. Nevada generally permits underwriting outside the protected 6-month window.

What are Medicare Advantage trial rights?

Federal rules give certain first-year Advantage enrollees a protected path back to Medigap without underwriting. The protection is limited to specific first-year situations, so the window is narrow.

When can an Advantage plan be dropped?

The annual enrollment period runs October 15 through December 7 each year, when Advantage enrollees can change plans or return to Original Medicare for the following year.
