There Is No Medicare Appeal When a Medigap Insurer Says No at 72. No Federal Form, No Hearing, Just the Next Company’s Application.

A 72-year-old in Ohio opens her Medigap renewal notice and sees the premium jump again. She calls a broker to shop for a cheaper Plan G, answers the health questions truthfully, including heart medication and a 2024 stent, and gets declined.

She calls Medicare. The representative is polite and clear: Medicare does not review a private insurer’s medical-underwriting decision. There is no federal appeal form, no administrative hearing, and no judge waiting at the next level. The good news is easy to miss in the frustration. The rejection does not cancel the Plan G policy she already owns. It closes one application, not her coverage.

Why Medicare Cannot Review the Decision

Medigap is private insurance governed by federal standards and state insurance law. Plans carrying the same letter deliver the same standardized core benefits, but insurers set their own premiums and, when underwriting is permitted, decide which applicants meet their health requirements. Every beneficiary receives one six-month Medigap Open Enrollment Period beginning the first month they are at least 65 and enrolled in Medicare Part B. During that window, an insurer cannot reject an application or charge more because of health history.

Federal guaranteed-issue rights also attach in certain situations, including some involuntary losses of coverage. Outside those protections, insurers in most states can ask health questions, review prescription and medical records, and decline an application. That is fundamentally different from Medicare Advantage. A Medicare Advantage coverage denial can move through five federal appeal levels, beginning with a plan reconsideration at Level 1 and potentially reaching federal district court at Level 5. A Medigap underwriting rejection is not a Medicare coverage decision, so that appeals ladder simply does not apply.

What Recourse Still Exists

Medigap underwriting guides are not identical across carriers. The timing of a stent, current medications, and the length of a carrier’s lookback period can produce a rejection from one company and an approval from another. A broker representing several carriers can compare those rules against the applicant’s specific health history before a formal application is ever submitted, which is far more productive than sending the same file blindly from company to company.

The declined applicant can also ask why she was rejected and check the medical or prescription records the carrier used. If those records contain an error, or a temporary condition has since resolved, she can ask whether the carrier will reconsider with updated documentation. That is a company-level review, not a Medicare appeal. State insurance regulators offer another avenue. A Department of Insurance can investigate whether the carrier violated a guaranteed-issue right, misapplied an approved underwriting rule, or failed to follow state law, but it cannot ordinarily force a company to accept someone who simply does not meet lawful underwriting standards.

Federal law sets the floor, and state law can build above it. Four states, New York, Connecticut, Maine, and Massachusetts, require insurers to offer Medigap on a guaranteed-issue basis year-round or on a recurring annual basis without regard to health status. Beyond those four, as of 2026 another 15 states have enacted birthday rules or anniversary rules that give existing Medigap policyholders an annual window to switch plans without medical underwriting. New Mexico is scheduled to join that group in 2027. Those narrower rules generally protect policyholders who already carry Medigap, however, and may not help someone trying to move from Medicare Advantage into Medigap for the first time.

The Policy She Has Is Her Leverage

Her current Medigap policy is generally guaranteed renewable. As long as she pays the premium and did not obtain the policy through fraud or a material misrepresentation, the insurer ordinarily cannot cancel it because she developed heart disease or filed large claims.

The carrier can raise premiums under its approved rating method, but it cannot single her out for an individual surcharge because of the stent. Her real choice is not between an expensive Plan G and no coverage at all. It is between keeping the policy, finding another carrier willing to approve her, or changing how she receives Medicare during a valid enrollment period.

Dropping Plan G before another policy is in hand is where things get dangerous. Original Medicare carries no annual out-of-pocket maximum. Without a supplement, a beneficiary faces the $1,736 Part A deductible for each benefit period, $434 per day in hospital coinsurance for days 61 through 90, and $217 per day in skilled nursing facility coinsurance for days 21 through 100 in 2026.

Keep the Policy While Testing the Market

The safest sequence keeps the current Plan G intact until another option is more than a quote:

1. Ask a multi-carrier broker to compare the exact health history and medication list against several underwriting guides before submitting a formal application.
2. If a carrier declines, request the reason in writing, correct any inaccurate medical information, and check whether state law or a guaranteed-issue right applies. The state insurance department and State Health Insurance Assistance Program can both help identify those protections.
3. Do not cancel the current Plan G until a replacement policy has been issued in writing with a confirmed effective date. If no Medigap carrier approves the application, compare Medicare Advantage options during an available enrollment period before making any change.

The denial closes one application, not the policy already in hand. Keeping that policy in force while checking every other door is how she shops from a position of strength.

Editor’s note: This article was updated to reflect that four states (New York, Connecticut, Maine, and Massachusetts) require year-round or recurring guaranteed-issue Medigap access, replacing the previous reference to only two states. The birthday-rule count has been updated to 15 states currently in effect for 2026, with New Mexico set to join in 2027. All 2026 Medicare cost figures ($1,736 Part A deductible, $434 daily hospital coinsurance for days 61 through 90, and $217 daily skilled nursing facility coinsurance for days 21 through 100) were confirmed against CMS published amounts.
