Quick Read

• Medicare cannot appeal a Medigap insurer's rejection. Unlike Medicare Advantage denials, private underwriting decisions have no federal appeal process, form, or hearing.

• An existing Medigap policy is guaranteed renewable and cannot be canceled due to new health conditions, making it powerful leverage while shopping.

• Underwriting rules vary by carrier, so a multi-carrier broker can compare guidelines before submitting a formal application to improve approval odds.

• Many financial professionals are salespeople paid on what they push, not whether you end up wealthier. A fiduciary is the opposite. The SEC legally requires them to put your interests first.

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.

Why Medicare Cannot Review the Decision

Medigap is private insurance governed by federal standards and state insurance law. Plans carrying the same letter provide the same standardized core benefits, but insurers set their premiums and, when underwriting is permitted, decide which applicants meet their health requirements. A 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, insurers cannot reject the application or charge more because of health.

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

What Recourse Still Exists

Medigap underwriting guides are not identical. The timing of a stent, current medications and the length of a carrier's lookback can produce a rejection from one company and an approval from another. A broker representing several carriers can compare those rules before submitting a formal application. That is more useful than sending the same health history blindly from company to company.

The applicant can also ask why she was declined and check the medical or prescription information used. If the record contains an error, or a temporary condition has since been resolved, she can ask whether the carrier will reconsider with updated documentation. That is a company review, not a Medicare appeal. State insurance regulators provide another lane. 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. It cannot ordinarily force a company to accept an applicant who simply does not meet lawful underwriting standards.

Federal law sets the floor, but state law can create broader access. New York and Connecticut provide unusually broad Medigap protections, while several other states offer narrower birthday or anniversary rules. Those narrower rules often help existing Medigap policyholders switch plans and may not protect someone moving 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 used the coverage heavily.

The carrier can raise premiums under its approved rating method, but it generally cannot single her out for an individual increase because she had a stent. Her immediate choice is therefore not between expensive Plan G and no coverage. It is between keeping the policy, finding another carrier that will approve her or changing how she receives Medicare coverage during a valid enrollment period.

Dropping Plan G before another policy is issued creates the real danger. Original Medicare has no annual out-of-pocket maximum. Without a supplement, a beneficiary can face the $1,736 Part A deductible for each benefit period, $434 daily hospital coinsurance for days 61 through 90 and $217 daily skilled nursing 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 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.
