Which one of the following statements best describes the purpose of Medicare Supplement insurance?

Editorial team Published on

The statement that best describes the purpose of Medicare supplement insurance (also known as Medigap) is that it is private health insurance designed to fill coverage gaps left by Original Medicare (Part A and Part B).

Specifically, its primary purpose is to help pay for the out-of-pocket medical costs that Original Medicare does not fully cover, such as:

  • Copayments
  • Coinsurance (like the 20% patient coinsurance under Part B)
  • Deductibles

💡 Core Rules Governing Medigap

  • Eligibility: You must already be enrolled in both Medicare Part A and Part B to buy a supplement policy.
  • Exclusions: Standard Medigap policies sold today generally do not cover long-term care (like custodial nursing home care), vision, dental, hearing aids, or private-duty nursing. They also do not cover prescription drugs, which are handled under Part D.
  • Advantage Restriction: It is illegal for an insurance company to sell you a Medigap policy if you are enrolled in a Medicare Advantage (Part C) plan.

What best describes the purpose of Medicare Supplement insurance?

The primary purpose of a Medicare supplement (Medigap) policy is to help pay for out-of-pocket healthcare costs not covered by Original Medicare, such as deductibles, coinsurance, and copayments.

Key Purposes and Functions

  • Fill Coverage Gaps: They cover costs left over after Original Medicare pays its share of approved medical services.
  • Reduce Out-of-Pocket Expenses: They limit your exposure to unexpected hospital, medical, and surgical bills.
  • Work Alongside Medicare: They are sold by private insurance companies to supplement—not replace—Original Medicare Parts A and B.

What Medigap Policies Do NOT Do

  • No Prescription Drugs: They do not include prescription drug coverage (which requires a separate Part D plan).
  • No Extra Routine Care: They generally do not cover long-term care, vision, dental care, or hearing aids.
  • Not for Medicare Advantage: You cannot use a supplement policy if you are enrolled in a Medicare Advantage (Part C) plan.

What is the purpose of Medicare supplemental insurance?

The purpose of Medicare Supplement Insurance (Medigap) is to help pay for the out-of-pocket healthcare costs that Original Medicare (Parts A and B) does not cover.

How It Works

  • Fills Coverage Gaps: Original Medicare pays for many care costs, but leaves behind gaps like coinsurance, copayments, and deductibles. Medigap covers some or all of these remaining costs.
  • Works with Original Medicare: You must have Original Medicare Parts A and B to buy a supplement plan; it works alongside your government benefits rather than replacing them.
  • Standardized Benefits: Private insurance companies sell these policies, which are labeled by letters (like Plan G or Plan N). Plans with the same letter offer the exact same basic benefits.

Key Benefits

  • Predictable Costs: It reduces large, unexpected medical bills by turning unpredictable care costs into a steady monthly premium.
  • No Network Restrictions: You can visit any doctor or hospital in the United States that accepts Medicare patients.
  • Guaranteed Renewable: Private insurers cannot cancel your policy as long as you pay your monthly premium on time.

What It Does Not Cover

  • Prescription Drugs: Medigap policies do not include drug coverage, so you need a separate Medicare Part D plan.
  • Routine Care: They generally do not pay for long-term custodial care, dental work, vision care, or hearing aids.

Which of the following statements is true about a Medicare Supplement insurance plan member?

The true statement is that Medicare Supplement Insurance cannot be used in conjunction with a Medicare Advantage (MA) Plan; therefore, after receiving confirmation of enrollment into an MA Plan, the member must manually cancel their Medicare Supplement policy according to their carrier's rules.

Explanation of the Correct Answer

  • ✅ Mutually Exclusive Coverages: Medicare Supplement (Medigap) plans only work alongside Original Medicare. They cannot be used to pay for out-of-pocket costs if a member switches to a private Medicare Advantage Plan.
  • ✅ No Automatic Cancellation: Enrolling in a Medicare Advantage plan does not automatically trigger the cancellation of a Medicare Supplement policy. The policyholder remains responsible for paying the Medigap premiums until they explicitly contact their insurance carrier to cancel it.

Why Other Common Options Are Incorrect

  • ❌ Incorrect: The Medicare Supplement plan will automatically cancel upon MA enrollment. As noted above, there is no system communication that auto-cancels a Medigap plan. It must be handled manually by the policyholder.
  • ❌ Incorrect: The plans work together to cover remaining copays. Medigap policies cannot pay out for secondary costs under an MA plan network. It is actually illegal for an insurance agent to sell someone a Medigap policy if they know that person is enrolled in an MA plan.
  • ❌ Incorrect: The member must cancel their Supplement policy on the exact same day they apply for an MA plan. The member should wait until they receive official confirmation of enrollment from the MA plan before canceling their Supplement coverage to avoid an accidental gap in insurance.

Explanation of Common Test Variations

❌ Incorrect Options to Avoid:

  • A copy of the MIB (Medical Information Bureau) report: This is an underwriting tool and is never mandatory inside the policy or its outline.
  • Projections of future costs: Insurance companies cannot accurately predict future medical cost adjustments, so this is not required.
  • The agent's contact information: While helpful, it is legally not a mandatory element of the policy's standardized Outline of Coverage.
  • Outpatient prescription drug coverage: Modern Medigap policies sold after 2005 are explicitly prohibited from including prescription drug coverage (which is handled by Medicare Part D).

What is an example of a Medicare Supplement?

Medicare Supplement (Medigap) plans are standardized private insurance policies labeled Plans A through N that pay for out-of-pocket costs like deductibles, coinsurance, and copayments left over by Original Medicare.

You can review details and search for policies using the official Medicare Medigap Overview.

Popular Medigap Plan Examples

  • Plan G: This is the most comprehensive plan generally available to people newly eligible for Medicare. It covers all gaps in Original Medicare except for the annual Part B deductible ($283 in 2026).
  • Plan N: This plan offers lower monthly premiums with high coverage, but you pay a copayment of up to $20 for some doctor visits and up to $50 for emergency room visits, plus the annual Part B deductible.
  • Plan F: This is the most comprehensive plan covering all Medicare cost-sharing gaps, including the Part B deductible. However, it is only available if you were eligible for Medicare before January 1, 2020.
  • Plan A: This is the most basic plan. It covers fundamental benefits like hospital coinsurance and the 20% Part B coinsurance, but it does not cover deductibles.

Other Standardized Plan Examples

  • Plan B: Covers basic benefits of Plan A plus the Medicare Part A hospital deductible.
  • Plan C: Comprehensive coverage that includes the Part B deductible, but restricted to those eligible for Medicare before January 1, 2020.
  • Plan D: Covers most core benefits except for the Part B deductible and excess charges.
  • Plans K and L: Offer partial coverage (50% for Plan K, 75% for Plan L) of certain costs until you reach an annual out-of-pocket spending limit.
  • Plan M: Covers 50% of the Part A hospital deductible along with basic benefits.

Which is better, the Medicare Supplement plan F or G?

Medicare Supplement Plan G is generally considered the better overall choice because it offers nearly identical coverage to Plan F while typically featuring lower monthly premiums and better long-term price stability.

According to community consensus on Reddit, users note that Plan F is being phased out, leading to a closed pool of policyholders that can age and experience faster rate increases. You can read more detailed breakdowns on the NerdWallet Medigap Plan F vs. Plan G Guide.

Key Differences

  • Eligibility: Plan F is only available to people who became eligible for Medicare before January 1, 2020. Plan G is open to all Medicare beneficiaries.
  • Part B Deductible: Plan F covers the annual Medicare Part B deductible ($283 in 2026), meaning you have zero out-of-pocket costs for approved services. Plan G does not cover this deductible; you pay it out of pocket once per year before coverage kicks in.
  • Coverage: Once the Part B deductible is met for Plan G, both plans cover 100% of all other Medicare-approved out-of-pocket costs, coinsurance, and excess charges.

Cost Comparison

  • Premiums: Plan F usually costs more per month because it covers the Part B deductible.
  • The Math: If the annual price difference between Plan F and Plan G is more than the Part B deductible ($283), Plan G saves you money. If Plan F costs less than $23.58 more per month than Plan G, Plan F might be a better financial deal. However, rate hikes on the closed Plan F pool often make Plan G cheaper over time.

What is the best Medicare Supplement plan?

Plan G is the best and most comprehensive Medicare Supplement (Medigap) plan available for anyone new to Medicare.

Because Medigap plans are standardized by the federal government, a Plan G from one private insurance company offers the exact same core benefits as a Plan G from any other company.

Top Medicare Supplement Plans

  • Plan G (Best Overall for New Enrollees): Covers 100% of your Original Medicare out-of-pocket expenses, leaving you responsible only for the annual Part B deductible.
  • Plan F (Best for Pre-2020 Enrollees): Covers every single out-of-pocket cost, including the Part B deductible. However, it is legally restricted and only available to those who were eligible for Medicare before January 1, 2020.
  • Plan N (Best Value / Budget-Friendly): Offers lower monthly premiums than Plan G, but you must pay small copayments for certain office ($20) and emergency room ($50) visits, plus any Part B excess charges.
