Medicare Supplement Plans

Save Money on Your Medicare Supplement Plans

Medicare Supplement Plans are part of what some call Medicare Part C. The other component of Medicare Part C is Medicare Advantage Insurance, which is covered elsewhere.

Medicare Supplement Plan is designed to cover the 20% of health claims that are not covered by Medicare Parts A & B. This coverage is not cheap, but it addresses the desired purpose of filling in the gaps in coverage created because Parts A & B only cover 80% of the claim costs. However, do not confuse this with Medicare Advantage Plans. They also cover the gap but they have various limitations and deductibles.

Medicare Supplement Insurance Plan Advantages:

Seamless: When combined with Medicare Parts A&B, this coverage, though subject to a small deductible (in many cases less than $200), does provide coverage wherever Medicare Coverage is accepted. It does not however cover vision, dental or drugs. (Drugs are covered by Medicare Part D).
Widely Accepted: With Medicare Supplement Insurance you can generally use your own doctor who accepts Medicare Payments and you can use it in all states, where Medicare Coverage is accepted.
Broad Coverage: While other plans might cover dental, vision and drugs, they would generally have deductibles and/or co-pays or life/annual limits, which are not generally true for Medicare Supplement Plans.
Changes: While Medicare Supplement Plan is more costly than Medicare Advantage Plans, which do cover dental, vision and drugs, it is sometimes considered the best way to start your retirement coverage as it does cover so many medical related issues with out all the deductible, co-pay and annual limit issues.

Medicare Supplement Insurance Plan Disadvantages:

Other Coverages: Vision, Dental and Drug Coverages are generally covered under Medicare Advantage Plans and not under Medicare Supplemental Plans. Vision and dental coverages are smaller issues and usually have limited coverage anyhow, but you will have to contract separately for these when you have Medicare Supplement Insurance.
Drugs: Drug Coverage is also not covered under Medicare Supplemental Insurance. This is a big deal, but if you have Medicare Insurance you can contract separately for Medicare Part D (Drugs), when you contract for Part B. Part D covers most all drugs while Medicare Advantage Plans have different prices and different coverages (including no coverage) for each type of drug, so you need to make certain the Medicare Advantage Plan you chose covers your required drugs. Medicare Part D (Used with the Medicare Supplement Plans) does cover most all drugs.

Things to Consider

Medicare Supplement Plan is different from Medicare Advantage Insurance and is in many cases more expensive, but it does fill the 20% of claim costs not covered by Medicare parts A & B.

However, the trend in medicare insurance is toward the Medicare Advantage Plans where each procedure, each drug, each treatment, each specialty, etc., is covered by a separate coverage limit and some form of deductible or co-pay. Which is why generally you hear more advertising about Medicare Advantage Plans than Medicare Supplement Insurance. However, both are part of Medicare Part C.

EINSURANCE Recommendation

EINSURANCE recommends that it is best, as a new user of Medicare Coverages, to start with Medicare Supplement Insurance and Medicare Part D (Drug Coverage) and then transfer to Medicare Advantage Plans once you are fully aware of all your medical issues and what coverages and drugs are most important to you. You can change your selection each year during the open enrollment period (also called, OEP).

Frequently Asked Questions (FAQs)

Get clear answers to common insurance questions and important details to guide your coverage decisions.

What are Medicare Supplement (Medigap) plans and why might I need one?

Medicare Supplement plans help cover costs not paid by Original Medicare, like deductibles, copays, and coinsurance. They help reduce your out-of-pocket expenses.

Who is eligible to enroll in a Medicare Supplement plan?

You must be enrolled in Medicare Parts A and B and reside in the state where the Medigap plan is offered. Some states offer coverage to those under 65 with disabilities.

When is the best time to enroll in a Medigap plan?

The ideal time is during your Medigap Open Enrollment Period — the 6-month window after turning 65 and enrolling in Part B — when you can’t be denied for health conditions.

What types of Medigap plans are available and how do they differ?

Plans are labeled by letter (e.g., Plan A, G, N) and standardized across most states. Each letter offers a different set of benefits, though coverage under each letter is consistent regardless of the insurer.

What do Medigap plans cover and what do they not cover?

Medigap covers costs like Medicare Part A/B deductibles, coinsurance, and foreign emergency care. It doesn’t cover prescription drugs, vision, dental, hearing aids, or long-term care.

How much will a Medicare Supplement plan cost me?

Costs vary based on plan type, provider, your location, and age. Premiums may use attained-age, issue-age, or community-rated pricing models. You must still pay your Part B premium.

Can my Medigap plan be cancelled because of my health or claims?

No. As long as you pay your premiums and provided accurate information at enrollment, your Medigap policy is guaranteed renewable—even if your health changes.

Does switching from a Medicare Advantage plan affect my eligibility for Medigap?

Yes. You generally cannot have both Medigap and Medicare Advantage at the same time. Switching may involve underwriting if you’re outside your Medigap enrollment window.

What should I ask or check when comparing Medigap plans via EINSURANCE?

Compare plan letters, premiums, pricing method, insurer reputation, and rate history. Make sure your doctors accept Medicare assignment and understand any exclusions.

How do I apply for a Medigap plan through EINSURANCE, and how does claims handling work?

Use EINSURANCE to enter your ZIP code and preferences, compare plan options, then enroll through the provider. Claims are managed by the insurer, not EINSURANCE.
