When Is a Medicare Supplement Consumer Subject to Underwriting?

Medicare Supplement (Medigap) plans help cover costs Original Medicare (Parts A and B) does not fully pay, such as deductibles, copayments, and coinsurance. Acquiring a Medigap policy often involves underwriting, a process insurers use to evaluate an applicant’s health risk. This assessment determines eligibility and the premium charged. Understanding when underwriting applies, or when it can be avoided, is important for consumers seeking supplemental health coverage.

What Medicare Supplement Underwriting Means

Medical underwriting is a process private health insurance companies use to assess an applicant’s health status before issuing a Medigap policy. This evaluation helps insurers determine the likelihood of future claims, impacting whether they offer coverage and at what cost. The process typically involves reviewing the applicant’s medical history, current health conditions, and medications. Insurers may request medical records or a comprehensive health questionnaire.

The information gathered helps gauge the financial risk. Based on this assessment, an applicant might be accepted at a standard premium rate. Coverage could also be offered with a higher premium due to identified health risks, or the application may be denied if the health risk is too substantial. Underwriting is a common practice in the insurance industry, designed to establish an appropriate premium or determine insurability based on health.

When Underwriting is Not Required

Consumers can avoid medical underwriting for a Medigap policy during specific periods or under certain circumstances, often referred to as guaranteed issue rights. The most common and widely available protection is the Medigap Open Enrollment Period. This is a one-time, six-month period that begins the month an individual is both age 65 or older and enrolled in Medicare Part B. During this window, insurers cannot deny coverage, charge a higher premium due to health conditions, or impose waiting periods for pre-existing conditions. This period offers the broadest access to Medigap plans at the most favorable rates, regardless of health status.

Beyond the initial open enrollment, federal law provides guaranteed issue rights in various situations. One common scenario arises when an individual loses employer-sponsored group health coverage, including COBRA, that supplemented Medicare. Another instance is if a Medicare Advantage (MA) plan leaves the Medicare program, stops serving the area, or if the individual moves out of the MA plan’s service area. In these cases, individuals typically have a 63-day period to apply for a Medigap policy after their previous coverage ends.

Trial rights also provide guaranteed issue protections. For example, if an individual enrolls in an MA plan when first eligible for Medicare at age 65, they may have a right to switch back to Original Medicare and purchase a Medigap policy within the first 12 months. Similarly, if a Medigap insurer goes bankrupt or terminates a policy through no fault of the policyholder, a guaranteed issue right is triggered. These federal protections ensure consumers are not left without supplemental coverage in situations beyond their control.

When Underwriting is Required

Outside of the specific periods and situations that grant guaranteed issue rights, consumers are generally subject to medical underwriting when applying for a Medicare Supplement plan. If an individual misses their one-time, six-month Medigap Open Enrollment Period, insurers are no longer obligated to offer a policy without considering their health. In such cases, the insurance company can evaluate the applicant’s medical history and potentially deny coverage or charge a higher premium based on pre-existing conditions.

Voluntarily switching Medigap plans after the initial open enrollment period typically requires underwriting. For instance, if a consumer already has a Medigap policy but wishes to change to a different plan or a different insurance company, they will likely need to go through the underwriting process. The new insurer will assess their health, and acceptance is not guaranteed.

Similarly, if an individual initially chose a Medicare Advantage plan and later decides to switch to Original Medicare combined with a Medigap plan outside of any guaranteed issue trial periods, they will generally face medical underwriting. Applying for a Medigap policy outside of protected enrollment windows means the insurer has the right to assess health risks and make coverage decisions accordingly.

State Variations in Underwriting Rules

While federal rules establish the Medigap Open Enrollment Period and certain guaranteed issue rights, individual states have the authority to implement additional regulations regarding Medigap underwriting. These state-specific laws can provide extra opportunities for individuals to obtain or switch Medigap policies without medical underwriting.

Several states have adopted a “Birthday Rule” or “Anniversary Rule,” which allows Medigap policyholders to switch to a different Medigap plan, often of equal or lesser benefits, without underwriting around their birthday or policy anniversary. The specific timeframe for this rule varies by state; for example, California allows a 60-day window. These rules are beneficial for those who want to change their plan but may have developed health conditions since their initial enrollment.

Some states offer continuous open enrollment or broader guaranteed issue rights year-round. For instance, in states like Connecticut, Massachusetts, and New York, Medigap policies are guaranteed issue throughout the year, meaning insurers cannot deny coverage or charge more based on health status at any time.

State laws also vary concerning Medigap access for individuals under age 65 who qualify for Medicare due to disability. While federal law does not mandate guaranteed issue for this group, many states require insurers to offer at least one Medigap plan to these beneficiaries, though premiums can sometimes be higher or vary.
