Best Medicare Supplement Plans: 2024’s Medigap Providers Ranked
Medicare, which currently insures nearly 64 million Americans, covers a wide range of medical and health care expenses, but it won’t cover everything. Coinsurance, hospital fees, copayments, blood transfusions, and extended skilled nursing facility stays all fall outside of Medicare coverage, making it essential to purchase a Medigap policy.
Medigap plans, also known as Medicare Supplement Insurance, are a type of policy that covers the “gaps” in one's Medicare coverage. As people get older and their likelihood of needing medical care increases, a Medigap policy helps defray out-of-pocket costs.
In this guide to the best Medigap providers, we'll walk through several of our favorite Medigap providers and explore what sets them apart from the competition.

How We Chose the Best Medigap Providers
Since Medigap policies are federally regulated, the actual coverage you receive will be identical from company to company. For example, a Medigap Plan C from Cigna will offer the same benefits as Aetna’s Plan C. The companies on this list, however, provide some additional services that help them rise above hundreds of other Medigap providers.
Here’s what we looked for:
- Nationwide availability: Few insurers offer Medigap policies in every state, but we looked for insurers that offered coverage in 40 or more states. Some of these providers even allow you to keep your policy upon relocating to another state.
- Transparent pricing: From free online quotes to guarantees that your premiums won’t rise with age, we looked for providers that make it very clear what you’re paying for.
- Extra perks: Our favorite Medigap providers offer extra benefits for policyholders, such as household discounts, fitness programs, and savings on healthcare services.
- Financial stability: Using data from AM Best, we made sure each of these providers rated highly in financial health and reliability, ensuring that you'll be able to get the coverage you're entitled to.
- In-person agents: In an increasingly digital world, we value when a company has in-person agents available to walk you through the details of your insurance policy.
Bottom Line
While individual Medigap plans are created equal in terms of coverage, they differ in terms of premiums, availability, and extra perks. To get started, we recommend taking a look at our individual provider pages. Additionally, be sure to check out our helpful guides:
Medigap Frequently Asked Questions
-
Can you be denied Medigap coverage?
Connecticut, Maine, Massachusetts, and New York require insurers to sell policies to all Medicare beneficiaries. In all other states, however, insurers may deny you coverage if you enroll outside of the Initial Enrollment Period, that is, the 7 months during which you’re Eligible for Medicare (three months before to three months after your 65th birthday).
-
Is Medigap better than Medicare Advantage?
If you can afford the higher premiums, we always recommend enrolling in Medigap (with Original Medicare) as opposed to Medicare Advantage, as MA plans will restrict your networks.
-
Can you switch Medigap plans?
Switching Medigap plans can be difficult depending on the company, but it can be done. Generally, the best time to switch policies is during your Medigap open-enrollment period.
-
What is the most popular Medigap plan?
In my experience, Medigap Plan F is the most popular since it offers the most comprehensive coverage.
-
Does Medigap cover prescription medications?
No Medigap plan covers prescription medications, but most companies offer separate plans that can be used to cover these costs.
-
Can the insurance company cancel my Medigap plan?
In most cases, an insurer can’t cancel your Medigap coverage except for one of three reasons: you stop paying your premium, you lied on your application, or the company goes bankrupt or becomes insolvent.
