More than 14 million Americans rely on Medigap coverage for Medicare beneficiaries to fill in the gaps that Original Medicare doesn’t cover and nearly all of them are satisfied with their coverage according to a survey by AHIP.

Here’s why this option is gaining popularity in 2025—and how you can get expert help from Senior65.com, for free.

What Is Medigap and Who Is It For?

Medigap coverage for Medicare beneficiaries is supplemental insurance that helps pay for out-of-pocket expenses not covered by Original Medicare—like deductibles, copays, and coinsurance. These plans are offered by private insurers and are standardized by the government.

Medigap is no longer just a “backup” plan—it’s becoming the go-to solution for Medicare enrollees who want predictable costs and reliable coverage. In 2025, over 14 million people are enrolled in Medigap plans (41%), and according to the  America’s Health Insurance Plans (AHIP), that number continues to grow, increasing for the fifth consecutive year.

Why More Medicare Beneficiaries Choose Medigap Every Year?

One word: predictability. Medigap offers consistent, reliable coverage that gives you more control over your care—and your wallet. Original Medicare (Parts A and B) covers a lot—but not everything. You’re still responsible for copays, coinsurance, and deductibles. Medicare typically requires patients to pay 20% or more for doctor visits, hospital stays etc. That’s where Medigap comes in. These plans work to cover the “gaps” in your coverage and keep surprise bills from catching you off guard.

People with Medigap are happier with their coverage.They enjoy seeing any Medicare doctor and avoiding big medical costs. In fact, the report shows that:

  • 93% of Medigap enrollees were satisfied with their Medigap plan.
  • 96% said they had access to their healthcare providers, and
  • nearly 90% said their Medigap plan makes it easier to afford needed care.

That’s powerful peace of mind—especially when compared to plans with networks and unexpected costs. (source)
