Medicare Supplement Insurance, also known as Medigap, is a type of policy designed to fill the coverage gaps left by Original Medicare. While Medicare Parts A and B cover a significant portion of your healthcare expenses, there are still out-of-pocket costs that can add up, such as deductibles, copayments, and coinsurance. Medigap plans are sold by private insurance companies and are standardized by the federal government to help reduce these costs. In this article, we’ll take a deep dive into Medigap plans, exploring how they work, what they cover, and how to choose the right plan for your needs.
What Is Medigap?
Medigap plans are supplemental insurance policies that work alongside Original Medicare. They help cover some or all of the costs that Medicare Parts A and B don’t fully pay for, such as deductibles, copayments, and coinsurance. Medigap plans are standardized in most states, meaning that each plan offers the same basic benefits regardless of the insurance company selling it.
How Medigap Plans Work
Medigap plans are designed to fill the gaps in coverage left by Original Medicare. Here’s how they work:
Secondary Coverage: After Medicare pays its share of your healthcare costs, your Medigap plan steps in to cover some or all of the remaining out-of-pocket expenses.
Standardized Plans: In most states, there are 10 standardized Medigap plans, labeled A through N. Each plan offers a different level of coverage, but the benefits are the same across insurance companies. This makes it easier to compare plans.
Medigap and Medicare Advantage: It’s important to note that you cannot have both a Medigap policy and a Medicare Advantage plan at the same time. Medigap is meant to supplement Original Medicare, while Medicare Advantage replaces it.
Coverage Provided by Medigap Plans
Each Medigap plan offers a different combination of benefits, but here’s a general overview of what they cover:
Part A Coinsurance and Hospital Costs: All Medigap plans cover Part A coinsurance and hospital costs for up to an additional 365 days after Medicare benefits are used up.
Part B Coinsurance or Copayment: Most Medigap plans cover Part B coinsurance or copayment costs, which are typically 20% of the Medicare-approved amount for doctor visits and other outpatient services.
Blood: Medigap plans cover the first three pints of blood each year, which are not covered by Original Medicare.
Part A Hospice Care Coinsurance or Copayment: Medigap plans help pay for hospice care costs that are not fully covered by Medicare.
Skilled Nursing Facility (SNF) Coinsurance: Some Medigap plans cover the coinsurance for skilled nursing facility care, which can be a significant expense.
Part A Deductible: Several Medigap plans cover the Medicare Part A deductible, which can reduce your out-of-pocket costs if you’re hospitalized.
Part B Deductible: Plan F and Plan C cover the Medicare Part B deductible. However, these plans are only available to individuals who were eligible for Medicare before January 1, 2020.
Part B Excess Charges: Some doctors charge more than the Medicare-approved amount for their services. Medigap Plans F and G cover these "excess charges," ensuring that you’re not responsible for the difference between what Medicare pays and what your doctor charges.
Foreign Travel Emergency: Many Medigap plans cover emergency healthcare services when you travel outside the U.S., typically up to 80% of the costs after you meet a deductible.
Types of Medigap Plans
Medigap plans are standardized into 10 different types, labeled A through N (though Plans C and F are only available to those eligible before January 1, 2020). Each plan offers a different combination of coverage levels:
Plan A: Provides the basic benefits, covering Part A coinsurance and hospital costs, Part B coinsurance, and the first three pints of blood.
Plan B: Offers the same coverage as Plan A, with the addition of coverage for the Part A deductible.
Plan C: Covers everything that Plan B covers, plus the Part B deductible. (Note: This plan is no longer available to new Medicare beneficiaries as of January 1, 2020.)
Plan D: Covers all the same benefits as Plan C, except for the Part B deductible.
Plan F: The most comprehensive Medigap plan, covering all out-of-pocket costs, including Part B excess charges and the Part B deductible. (Note: Like Plan C, Plan F is no longer available to new beneficiaries as of January 1, 2020.)
Plan G: Very similar to Plan F, but does not cover the Part B deductible. It’s a popular choice for those who want comprehensive coverage.
Plan K: Covers 50% of most benefits, including Part A deductible and skilled nursing facility coinsurance, but has a lower premium. It also has an out-of-pocket limit, which other plans do not.
Plan L: Similar to Plan K, but covers 75% of most benefits and has a higher out-of-pocket limit.
Plan M: Covers 50% of the Part A deductible and 100% of other basic benefits. It offers moderate coverage with lower premiums.
Plan N: Similar to Plan D but requires you to pay a small copayment for some doctor visits and emergency room visits. It’s a good option for those who want comprehensive coverage with lower premiums.
Costs Associated with Medigap Plans
Medigap plans typically come with higher premiums than Medicare Advantage plans, but they can save you money in the long run by reducing your out-of-pocket costs. Here’s what to consider:
Premiums: Medigap premiums vary depending on the plan, the insurance company, and your location. Generally, more comprehensive plans like Plan G have higher premiums.
Out-of-Pocket Costs: Medigap plans are designed to reduce your out-of-pocket costs by covering deductibles, coinsurance, and copayments. The extent of this coverage depends on the specific plan you choose.
No Network Restrictions: Unlike Medicare Advantage plans, Medigap policies do not have network restrictions. You can see any doctor or specialist who accepts Medicare, which provides greater flexibility, especially if you travel frequently.
Guaranteed Renewal: As long as you pay your premiums, your Medigap plan cannot be canceled, and your coverage cannot be dropped. This guarantees lifelong coverage, even if your health condition changes.
Enrollment and Eligibility
To purchase a Medigap policy, you must be enrolled in both Medicare Part A and Part B. The best time to buy a Medigap policy is during your Medigap Open Enrollment Period, which is a six-month period that starts the month you turn 65 and enroll in Medicare Part B. During this period, you have guaranteed issue rights, meaning you can buy any Medigap policy sold in your state without medical underwriting or being charged higher premiums due to pre-existing conditions.
If you miss this window, you can still apply for a Medigap policy later, but the insurance company may use medical underwriting to determine your eligibility and premium costs. In some states, you may also have additional rights to buy a Medigap policy.
Pros and Cons of Medigap Plans
Pros:
Predictable Costs: Medigap plans help reduce or eliminate out-of-pocket costs, providing peace of mind and financial predictability.
No Network Restrictions: You can see any doctor or specialist who accepts Medicare, offering flexibility and choice.
Guaranteed Coverage: As long as you pay your premiums, your Medigap plan is guaranteed renewable, meaning you’ll never lose coverage due to changes in your health.
Standardized Plans: The benefits of each Medigap plan are standardized, making it easier to compare options across different insurance companies.
Cons:
Higher Premiums: Medigap plans generally have higher monthly premiums than Medicare Advantage plans, which may not be affordable for everyone.
No Additional Benefits: Unlike Medicare Advantage plans, Medigap does not offer additional benefits like dental, vision, hearing, or prescription drug coverage. You’ll need to purchase a separate Part D plan for medications.
Limited Enrollment Periods: If you miss your Medigap Open Enrollment Period, you could be subject to medical underwriting, which might result in higher premiums or denial of coverage.
What to Consider Before Choosing a Medigap Plan
Healthcare Needs: Consider how often you visit the doctor, the type of care you need, and whether you prefer the flexibility of seeing any provider who accepts Medicare.
Budget: Assess your budget, including the monthly premium, out-of-pocket costs, and whether you can afford a separate Part D plan for prescription drugs.
Travel: If you travel frequently within the U.S., a Medigap plan might be a better fit due to its lack of network restrictions.
Enrollment Timing: Take advantage of the Medigap Open Enrollment Period to secure the best plan without medical underwriting.
Conclusion
Medigap plans offer robust coverage that can significantly reduce your out-of-pocket healthcare costs by supplementing Original Medicare. They provide flexibility, predictable expenses, and the assurance of lifetime coverage as long as you continue to pay your premiums. However, they come with higher premiums and do not include additional benefits like dental, vision, or prescription drug coverage.
