Introduction
You picked a Medicare Advantage (MA) plan, and now your preferred surgeon is out of network, a drug isn't on the formulary, or the copays add up faster than expected. Can you go back to Original Medicare with a Medigap policy?
Sometimes, yes. Federal trial rights protect certain first-time MA enrollees.
But Medicare Advantage now covers 35.2 million people, or 55% of eligible beneficiaries, according to KFF's 2026 update. Most of them lack a guaranteed way back to Medigap.
This guide covers who qualifies, how the 12-month trial works, the Medigap application window, Part D, and what to do if the trial right doesn't apply.
Key Takeaways
- A trial right is a limited guaranteed issue protection, not permission to switch plans at will.
- Two scenarios qualify: your first MA plan at age 65, or dropping Medigap to try MA once.
- The 12-month trial and the Medigap application window are separate clocks.
- Medigap and Part D don't start automatically. You must apply for both.
What Is a Medicare Advantage Trial Right?
Medicare Advantage, Original Medicare, and Medigap
Original Medicare is Part A (hospital) and Part B (medical). Medicare Advantage is a private-plan alternative that bundles those benefits and usually adds Part D drug coverage.
Medigap is different. It's private insurance that pays Original Medicare cost-sharing such as deductibles and coinsurance. It supplements Original Medicare, not MA, and you need both Parts A and B to buy it.
If your MA plan included drugs, returning to Original Medicare means you'll likely need a separate Part D plan.
How the Trial Right Protects a Return to Medigap
A trial right lets you return to Original Medicare and buy Medigap without medical underwriting. Under guaranteed issue, the insurer must offer coverage, can't impose pre-existing-condition exclusions, and can't charge more because of your health, per Medicare's guide.
What that means for you:
- Coverage is not automatic; you apply and submit proof of eligibility
- Leave MA within 12 months
- Apply for Medigap from 60 days before through 63 days after MA coverage ends
Trial Rights Versus Other Enrollment Periods
The MA Open Enrollment Period (January 1 to March 31) and the Annual Enrollment Period (October 15 to December 7) can get you back to Original Medicare. Neither guarantees Medigap acceptance.
Outside a protected period, insurers can use medical underwriting, charge more, or deny you. Pre-existing conditions can make Medigap hard or impossible to get.
Who Qualifies for the Medicare Advantage Trial Right?
Two federal pathways exist, and they work differently.
| Factor | Joined MA at 65 | Dropped Medigap to try MA |
|---|---|---|
| Entry | Joined MA when first eligible for Part A at 65 | Dropped Medigap to join MA for the first time |
| Exit | Within 12 months of MA effective date | During the first year |
| Policy rights | Any Medigap policy sold in your state | Your same policy from the same insurer, if still sold |
| Application window | 60 days before to 63 days after MA ends | Same |
Scenario 1: First MA Enrollment at Initial Eligibility
If you joined MA when first eligible for Medicare at 65 and it isn't working, you may buy any Medigap policy an insurer sells in your state. Plan availability depends on when you became eligible for Medicare.
Delayed Part B or employer coverage complicates timing. Confirm your Part A, Part B, and MA effective dates before acting.
A separate six-month Medigap Open Enrollment Period starts when you're 65 or older and enrolled in Part B. Don't confuse it with the trial right.
Scenario 2: Leaving Medigap to Try MA for the First Time
If you dropped a Medigap policy to try MA for the first time, you can generally return to the same policy from the same insurer if it's still offered.
If that policy is no longer sold, fallback guaranteed-issue plans apply. The exact list varies by source:
- Virginia regulation: A, B, C, F, high-deductible F, K, and L
- Medicare's guide: A, B, C, D, F, and G
Confirm your options with your state insurance department.
Medicare's guide also covers dropping Medigap to try Medicare SELECT for the first time. SELECT is a network-based Medigap policy, not MA.
Situations That May Not Qualify
- Switching from one MA plan to another doesn't create a new trial right.
- A second MA trial doesn't restart the protection.
- Returning to Original Medicare during a regular enrollment period doesn't guarantee Medigap.
Don't assume you're out of options, though. Other guaranteed issue events and state protections may apply.
How to Return to Medigap After Medicare Advantage
Step 1: Confirm Eligibility and Dates
Gather your MA effective date, any prior Medigap details, and whether this is your first MA enrollment. Then note your planned MA end date. The 12-month trial and the Medigap window are separate deadlines, so confirm both.
Step 2: Review Coverage Needs Before Leaving
Compare what you have with what you'd get:
- Doctors, hospitals, and network or referral rules
- Drug formularies and prior authorization
- Premiums, deductibles, copays, and MA out-of-pocket maximum
- Dental, vision, and hearing benefits
Original Medicare with Medigap often offers more provider flexibility. It doesn't include most routine dental, vision, or hearing benefits, and drug coverage requires a separate Part D plan.
Step 3: Start Disenrollment
Contact your MA plan, Medicare at 1-800-MEDICARE, or Medicare.gov to confirm the current process. Enrolling in a standalone Part D plan can also automatically disenroll you from MA. Special-election changes generally take effect the first day of the following month.
Keep the disenrollment confirmation or termination notice. You'll need it as proof.
Step 4: Apply for Medigap Within the Window
Apply from 60 days before through 63 days after your MA coverage ends. Medigap can't begin until MA ends, so coordinate the dates.
- Contact the insurer and request an official quote.
- State that this is a guaranteed issue (trial right) application.
- Submit proof of disenrollment with the application.
- Keep copies of every letter, notice, and email.
Your available policies depend on your scenario, whether your old policy still exists, your Medicare eligibility date, and state law.
Step 5: Arrange Part D and Coordinate Dates
Original Medicare doesn't include drug coverage. Timing differs by pathway:
- Joined MA at 65: you can elect a standalone Part D plan at the same time you leave MA.
- Dropped Medigap: a coordinating Part D election runs from the month you leave MA plus two more months, per CMS guidance.
Going 63 consecutive days or more without creditable drug coverage can trigger a late-enrollment penalty. Check formularies and pharmacies, then line up the end of MA, the start of Medigap, and the start of Part D so there's no gap.
If You Miss the Trial Right or Your Former Plan Is Unavailable
You may still return to Original Medicare during an enrollment period. Medigap acceptance just isn't guaranteed.
Possible consequences include:
- Medical underwriting and a higher premium
- Denial
- A pre-existing condition waiting period of up to six months
Plans C and F: people newly eligible for Medicare on or after January 1, 2020 can't buy them. Those eligible earlier may still be able to.
Other guaranteed issue events can include your MA plan leaving Medicare or your service area, or moving outside the service area. Each has its own rules, but applications often use the same window: 60 days before and 63 days after the event.
State rules matter. Virginia's birthday rule, effective July 1, 2025, gives existing Medigap holders 60 days from their birthday to switch to same-benefit coverage without underwriting. West Virginia's 2026 law requires 24 months of prior Medigap coverage.
Neither is a general right to move from MA to Medigap. Confirm current rules with your state insurance department or SHIP.
Conclusion
A trial right can be a valuable path back to Original Medicare and Medigap, but only if you fit a qualifying scenario and act within the deadlines.

Frequently Asked Questions
What are the top Medicare Supplement plans?
No single plan is best for everyone. Same-letter plans share the same basic benefits across insurers. Compare premiums, health needs, budget, and state availability; Plan G holds 39% of standardized enrollment per 2023 data.
Which Medicare Supplement plan is no longer available?
Plans C and F can't be bought by people newly eligible for Medicare on or after January 1, 2020. People eligible before then may still be able to buy them. Verify your eligibility date.
Are Medicare Supplement plans worth it?
It depends on your premiums, expected care use, budget, and comfort with cost-sharing. Original Medicare has no annual out-of-pocket cap, so Medigap adds protection. Compare it against your MA alternative.
Who qualifies for a Medicare Advantage trial right?
You qualify if you joined MA when first eligible for Medicare at 65, or if you dropped Medigap to try MA for the first time. Federal and state requirements apply.
How long do I have to apply for Medigap after leaving Medicare Advantage?
The window runs from 60 days before through 63 days after your MA coverage ends. Keep proof of disenrollment.
Can I get my old Medigap policy back after trying Medicare Advantage?
Generally yes, if the same insurer still sells it and you're in the dropped-Medigap scenario. If not, other guaranteed issue plans may apply, and state rules can add protections.
