Medigap coverage depends on the plan letter you select. Different plans cover different portions of Original Medicare’s cost-sharing responsibilities.
Common benefits may include:
Medicare Part A Coinsurance and Hospital Costs
Many Medigap plans help cover Medicare Part A hospital coinsurance and eligible hospital expenses after Original Medicare benefits are used.
Some plans also cover additional hospital costs for an extended period, subject to the policy’s benefits.
Medicare Part B Coinsurance and Copayments
Medicare Part B generally requires beneficiaries to pay coinsurance or copayments for covered outpatient services.
Depending on the policy, Medigap may cover some or all of these expenses.
Skilled Nursing Facility Coinsurance
Certain Medicare Supplement plans help pay skilled nursing facility coinsurance when Medicare covers the qualifying care.
This can reduce eligible out-of-pocket expenses associated with covered skilled nursing facility services.
Medicare Part A Deductible
Some Medigap plans cover the Medicare Part A inpatient hospital deductible.
The amount of coverage depends on the selected plan.
Foreign Travel Emergency Coverage
Certain Medigap plans provide limited coverage for emergency medical care received outside the United States.
This benefit is subject to specific conditions, coverage limits, and deductibles. Beneficiaries who travel internationally should review their policy documents carefully.
What Are the Different Types of Medicare Supplement Plans?
Medicare Supplement Insurance plans are standardized in most states and identified by letters. Each letter represents a specific package of benefits.
The available plans generally include A, B, D, G, K, L, M, and N. Plans C and F are also available to people who were eligible for Medicare before January 1, 2020.
Here is an overview of commonly available options:
| Medigap Plan | General Coverage Features |
|---|---|
| Plan A | Basic standardized benefits, including Part A and Part B coinsurance coverage. |
| Plan B | Plan A benefits plus coverage for the Medicare Part A deductible. |
| Plan C | Broad coverage, including the Part B deductible. Not available to people newly eligible for Medicare on or after January 1, 2020. |
| Plan D | Covers several Part A and Part B cost-sharing expenses, including the Part A deductible. |
| Plan F | Comprehensive coverage, including the Part B deductible. Restricted to people eligible for Medicare before January 1, 2020. |
| Plan G | Broad coverage, generally leaving beneficiaries responsible for the Part B deductible. |
| Plan K | Covers 50% of certain eligible cost-sharing expenses and includes an annual out-of-pocket limit. |
| Plan L | Covers 75% of certain eligible cost-sharing expenses and includes an annual out-of-pocket limit. |
| Plan M | Covers 50% of the Medicare Part A deductible and provides other standardized benefits. |
| Plan N | Covers many Medicare cost-sharing expenses but includes certain copayments and does not cover Part B excess charges. |
The exact benefits should always be checked against the official standardized plan comparison.
An important advantage of standardization is that policies with the same letter provide the same basic benefits, regardless of the insurance company selling them. However, premiums, customer service, and other company-specific features may differ.

When Can You Enroll in Medicare Supplement Insurance?
Timing is an important part of purchasing Medicare Supplement Insurance.
The best time for most beneficiaries to buy a Medigap policy is during their Medigap Open Enrollment Period.
This is a six-month period that begins on the first day of the month when you are both:
- 65 years old or older.
- Enrolled in Medicare Part B.
During this period, insurance companies generally cannot deny you a Medigap policy or charge you more because of pre-existing health conditions.
This enrollment protection gives beneficiaries an opportunity to choose from available policies without medical underwriting.
However, once this six-month period ends, federal rules generally allow insurance companies to use medical underwriting unless you qualify for guaranteed issue rights or other applicable protections.
Some states also provide additional enrollment opportunities and protections.

What Are Medigap Guaranteed Issue Rights?
Guaranteed Issue Rights are legal protections that allow eligible Medicare beneficiaries to purchase certain Medigap policies without medical underwriting.
These rights generally apply during specific circumstances when individuals lose qualifying healthcare coverage or experience certain changes involving their existing Medicare coverage.
Qualifying situations may include:
- Losing certain employer or union health coverage.
- Moving outside the service area of a Medicare Advantage plan when applicable protections apply.
- Having a Medicare Advantage plan leave Medicare or stop providing coverage in your area.
- Losing certain other qualifying health coverage.
The available Medigap policies and application deadlines depend on the qualifying event.
In many federal guaranteed issue situations, beneficiaries have a limited enrollment window, often beginning before their existing coverage ends and continuing for up to 63 days afterward.
State laws may provide additional protections.
Understanding these rights is important because missing an applicable deadline may affect your ability to purchase a policy without medical underwriting.

How Much Does Medicare Supplement Insurance Cost?
The cost of Medicare Supplement Insurance varies depending on several factors, including the plan letter, insurance company, location, age, and pricing method.
Unlike Medicare Advantage plans, Medigap policies generally charge a separate monthly premium in addition to the Medicare Part B premium.
Some important factors that influence Medigap premiums include:
Plan Selection: Plans with broader coverage may have higher premiums than plans with more limited benefits.
Age: Some insurance companies use age-based pricing methods that can affect premiums over time.
Location: Premiums may differ depending on the state and geographic area where the policy is purchased.
Insurance Company: Different companies may charge different premiums for the same standardized plan.
Pricing Method: Insurance companies generally use one of three pricing methods:
- Community-rated: Everyone with the same policy generally pays the same premium regardless of age.
- Issue-age-rated: Premiums are based on your age when you first purchase the policy.
- Attained-age-rated: Premiums are based on your current age and may increase as you get older.
When comparing costs, beneficiaries should request quotes from multiple insurance companies offering the same plan letter.
Medicare Supplement Insurance vs. Medicare Advantage
Medicare Supplement Insurance and Medicare Advantage are two different ways of arranging Medicare coverage.
Understanding the differences can help beneficiaries determine which option aligns with their coverage preferences and financial considerations.
| Feature | Medicare Supplement Insurance | Medicare Advantage |
|---|---|---|
| Coverage Structure | Works alongside Original Medicare | Provides Part A and Part B coverage through a private plan |
| Monthly Premium | Separate Medigap premium | May have an additional plan premium |
| Provider Access | Generally allows visits to providers nationwide who accept Medicare | Usually follows plan-specific provider network rules |
| Out-of-Pocket Costs | Helps pay eligible Original Medicare cost-sharing expenses | Includes an annual medical out-of-pocket maximum |
| Prescription Drugs | Requires separate Part D coverage in most cases | Many plans include prescription drug coverage |
| Additional Benefits | Standardized medical benefits, with limited additional benefits in some policies | May include dental, vision, hearing, and other benefits |
Medigap does not work with Medicare Advantage. Beneficiaries generally choose either Original Medicare with a supplemental policy or Medicare Advantage.
Medigap is designed to help cover certain expenses left by Original Medicare, while Medicare Advantage provides an alternative way to receive Medicare Part A and Part B benefits.

How to Choose the Right Medicare Supplement Plan
Selecting a Medicare Supplement plan requires evaluating your healthcare coverage preferences, budget, and available policy options.
Consider these factors before enrolling:
- Compare Plan Benefits: Review the standardized benefits associated with each plan letter.
- Evaluate Monthly Premiums: Compare prices from multiple insurance companies offering the same plan.
- Review Enrollment Eligibility: Determine whether you are within your Medigap Open Enrollment Period or qualify for guaranteed issue rights.
- Consider Prescription Coverage: Remember that most Medigap policies do not include prescription drug coverage. A separate Part D plan may be necessary.
- Check Insurance Company Reliability: Review the insurer’s reputation, financial stability, customer service, and premium history.
- Understand State Regulations: Check whether your state offers additional enrollment protections or different standardized plan options.
Taking time to compare these details can help you understand the coverage available and avoid making a decision based only on the monthly premium.
Conclusion
Medicare Supplement Insurance is designed to help beneficiaries manage certain healthcare expenses that Original Medicare does not fully cover. Also known as Medigap, these policies work alongside Medicare Part A and Part B to help pay eligible deductibles, coinsurance, and copayments.
Understanding the different plan letters, enrollment periods, premiums, and guaranteed issue rights is essential when evaluating supplemental coverage.
The six-month Medigap Open Enrollment Period is particularly important because it provides significant protections against medical underwriting for eligible beneficiaries.
Before selecting a policy, compare standardized benefits, insurance company premiums, provider access, and prescription drug coverage requirements. Reviewing these factors can help you make an informed decision about your Medicare coverage.
