Top 10 FAQs About Medicare Supplements (Medigap) Answered

TABLE OF CONTENTS

1. What is Medigap?

Explanation: Medigap, also known as Medicare Supplement Insurance, is designed to fill the gaps left by Original Medicare (Parts A and B). Original Medicare covers many healthcare services but not all expenses. Beneficiaries are often left with out-of-pocket costs such as deductibles, copayments, and coinsurance. Medigap policies, sold by private insurance companies, help cover these additional costs, providing financial security and reducing the burden of unexpected medical bills.
Details from Document: As outlined in the document, Medigap plans are standardized and regulated by the federal government. Each plan offers the same basic benefits regardless of the insurance company selling it. For example, Medicare Plan F, one of the most comprehensive plans, covers all Part A and Part B deductibles, copayments, and coinsurance. These plans ensure that beneficiaries have predictable healthcare costs and access to any doctor or hospital that accepts Medicare, offering peace of mind and financial stability.

2. What are the Different Medigap Plans Available?

Explanation: Medigap plans are standardized across most states and labeled with letters A, B, C, D, F, G, K, L, M, and N. Each plan offers a different combination of benefits, allowing beneficiaries to choose coverage that best fits their needs. Here’s a brief overview:
Plan A: Basic benefits including hospital coinsurance and costs after Medicare benefits are exhausted.
Plan B: Includes Plan A benefits plus coverage for the Medicare Part A deductible.
Plan C: Comprehensive coverage, including both Part A and Part B deductibles (Note: not available to new enrollees post-2020).
Plan D: Similar to Plan C but without coverage for the Part B deductible.
Plan F: Most comprehensive, covering all deductibles and coinsurance (also not available to new enrollees post-2020).
Plan G: Similar to Plan F but excludes the Part B deductible.
Plan K and L: Lower premiums with higher out-of-pocket costs, including partial coverage for services.
Plan M: Covers half of the Part A deductible and none of the Part B deductible.
Plan N: Covers Part A deductible and offers lower premiums with copayments for some services.
Details from Document: The document details how each plan is standardized and must offer the same benefits regardless of the insurer. For instance, Medicare Plan F provides extensive coverage, including all Medicare-approved expenses not paid by Parts A and B, ensuring minimal out-of-pocket costs for the beneficiary​.

3. How Does Medigap Differ from Medicare Advantage?

Explanation: Medigap and Medicare Advantage (Part C) are both options for supplementing Original Medicare, but they function quite differently. Medigap plans are supplemental insurance policies that cover out-of-pocket costs not paid by Original Medicare, such as deductibles, copayments, and coinsurance.
They work alongside Original Medicare, providing coverage across any provider that accepts Medicare nationwide.
Medicare Advantage plans, on the other hand, are an alternative to Original Medicare. These plans are offered by private insurance companies and typically include Parts A, B, and often D (prescription drug coverage). Medicare Advantage plans often have network restrictions, requiring beneficiaries to use a specified network of doctors and hospitals, and may offer additional benefits like vision, dental, and hearing coverage.
Details from Document: The document highlights that Medigap provides consistent, predictable costs and broader provider flexibility, as it is accepted by any provider that accepts Medicare. In contrast, Medicare Advantage plans may offer lower premiums but can include higher out-of-pocket costs, network restrictions, and the need for referrals to see specialists​.

4. What Does Medigap Cover?

Explanation: Medigap, or Medicare Supplement Insurance, helps cover costs that Original Medicare does not pay, including deductibles, copayments, and coinsurance. Depending on the plan chosen, Medigap can cover part or all of these expenses. For example, Medigap plans can cover the Part A hospital coinsurance and hospital costs up to an additional 365 days after Medicare benefits are exhausted, the Part A deductible, Part B coinsurance or copayment, the first three pints of blood, Part B excess charges, and foreign travel emergency care (up to plan limits).
Details from Document: The document outlines various Medigap plans and their specific benefits. For instance, Medicare Plan F covers all deductibles and coinsurance for Parts A and B, ensuring minimal out-of-pocket expenses for beneficiaries. Plan G, similar to Plan F, covers everything except the Part B deductible. Plan N provides lower premiums but includes copayments for some services, such as office visits and emergency room visits that do not result in an inpatient admission. These examples highlight how Medigap plans can offer comprehensive coverage, reducing financial stress and providing peace of mind.

5. Who is Eligible for Medigap?

Explanation: To be eligible for Medigap, individuals must be enrolled in both Medicare Part A and Part B. The best time to enroll in a Medigap plan is during the Medigap Open Enrollment Period, which begins on the first day of the month in which you turn 65 and are enrolled in Part B. This period lasts for six months. During this time, you have a guaranteed right to buy any Medigap policy sold in your state, regardless of health status. After this period, you may be subject to medical underwriting, and coverage could be more expensive or denied based on your health conditions.
Details from Document: The document emphasizes that to qualify for Medigap, you must be 65 years or older and enrolled in Medicare Part B. It also mentions special circumstances, such as losing other health coverage, which may grant you guaranteed issue rights to enroll in a Medigap plan outside the open enrollment period without medical underwriting. Additionally, some states offer Medigap plans to individuals under 65 who have disabilities or certain medical conditions.

6. When Can I Enroll in a Medigap Plan?

Explanation: The best time to enroll in a Medigap plan is during your Medigap Open Enrollment Period. This six-month period starts on the first day of the month in which you are both 65 or older and enrolled in Medicare Part B. During this time, you have a guaranteed right to buy any Medigap policy available in your state, regardless of your health condition. Insurers cannot use medical underwriting to deny coverage or charge higher premiums due to pre-existing conditions during this period.
Details from Document: The document highlights the importance of the six-month Medigap Open Enrollment Period for securing a policy without medical underwriting. If you miss this window, you may still apply for Medigap, but insurers can consider your health status and may charge higher premiums or deny coverage based on medical history. The document also mentions that in certain situations, such as losing other health coverage, you may have guaranteed issue rights, allowing you to enroll in a Medigap plan without underwriting outside the open enrollment period.

7. How Much Do Medigap Plans Cost?

Explanation: The cost of Medigap plans varies based on several factors, including the specific plan chosen, geographic location, age, gender, and tobacco use. Premiums can differ significantly from one insurer to another, even for the same coverage. Additionally, some states have community-rated pricing, where everyone pays the same premium regardless of age, while others use issue-age or attained-age pricing, which can affect how premiums increase over time.
Details from Document: The document explains that Medigap premiums are influenced by factors such as geographic location and the pricing model used by the insurer. For example, plans in areas with higher healthcare costs generally have higher premiums. Additionally, when choosing a plan, it is important to consider not just the monthly premium but also potential out-of-pocket costs, coverage details, and the insurer’s reputation. Comparing different plans and insurers can help beneficiaries find the best value for their needs​.

8. Can I Switch Medigap Plans?

Explanation: Yes, you can switch Medigap plans, but the process and considerations can vary. If you decide to switch outside of your Medigap Open Enrollment Period or a guaranteed issue right period, you may be subject to medical underwriting. This means insurers can deny coverage or charge higher premiums based on your health status. It’s essential to compare the benefits and costs of the new plan with your current one and consider the potential implications of switching.
Details from Document: The document states that while you can switch Medigap plans at any time, doing so outside of specific enrollment periods may require medical underwriting. Insurers can evaluate your health and potentially deny coverage or increase premiums based on pre-existing conditions. If you have guaranteed issue rights, such as losing other health coverage or moving out of your plan’s service area, you can switch plans without medical underwriting. It’s important to review these conditions and consult with a Medicare advisor to ensure a smooth transition

9. How Does Medigap Work with Other Insurance?

Explanation: Medigap is designed to supplement Original Medicare by covering out-of-pocket costs like deductibles, copayments, and coinsurance. However, it does not work in conjunction with other types of health insurance, such as employer-provided insurance, Medicaid, or Medicare Advantage plans. If you have employer-provided insurance, Medigap may not be necessary until that coverage ends. For those on Medicaid, Medigap is generally unnecessary because Medicaid already covers many of the out-of-pocket costs that Medigap would.
Details from Document: The document clarifies that Medigap policies are intended to work solely with Original Medicare. If you have other forms of insurance, like employer-provided coverage, Medigap may not be useful until that insurance ends. Additionally, Medigap cannot be used with Medicare Advantage plans. For Medicaid beneficiaries, Medigap is usually redundant since Medicaid often covers most out-of-pocket costs. An example from the document highlights that individuals with comprehensive employer insurance might delay purchasing Medigap until they lose their employer coverage, ensuring they don’t pay for unnecessary overlap in benefits

10. What are the Benefits of Having a Medigap Plan?

Explanation: Medigap plans offer several key advantages, including financial security and access to a broader range of healthcare providers. By covering out-of-pocket costs such as deductibles, copayments, and coinsurance, Medigap plans provide predictability and reduce the financial burden of medical expenses. Additionally, Medigap plans allow beneficiaries to see any healthcare provider that accepts Medicare, offering greater flexibility and choice compared to Medicare Advantage plans with network restrictions.
Case Example: Felix’s story highlights the benefits of having a comprehensive Medigap plan. Felix, an avid fisherman from Washington, opted for Medigap Plan F, which covers all deductibles and coinsurance for both Medicare Part A and Part B. When Felix experienced a heart attack, his Medigap Plan F ensured he had no out-of-pocket expenses for his extensive medical care, including a triple bypass surgery and a lengthy hospital stay. This comprehensive coverage provided Felix with peace of mind, allowing him to focus on his recovery without the added stress of medical bills.

Conclusion

Medigap plans offer essential benefits, including covering out-of-pocket costs, providing financial security, and allowing access to a broad range of healthcare providers. These plans supplement Original Medicare, filling the gaps left by Parts A and B. From understanding eligibility and enrollment periods to the advantages of comprehensive coverage like Plan F, Medigap plans ensure peace of mind for beneficiaries.
