Medicare Supplement insurance, commonly called Medigap, is designed to work alongside Original Medicare to help cover the out-of-pocket costs that Medicare Part A and Part B don’t pay. These costs can include deductibles, copayments, and coinsurance. Medigap policies are sold by private insurance companies but are standardized and regulated by the federal government.
With Medigap, Original Medicare pays its share of approved healthcare costs first, and your Medigap policy helps pay some or all of the remaining balance, depending on the plan you choose. This coordination can significantly reduce surprise medical bills and make healthcare expenses more predictable over time.
Medigap plans are labeled by letters (such as Plan A, G, or N), and each plan offers the same basic benefits no matter which insurance company sells it. For example, a Plan G from one carrier provides the same coverage as a Plan G from another — the difference is usually price, customer service, and rate stability. This makes it easier to compare plans and focus on value rather than complexity.
One of the biggest advantages of Medigap is flexibility. There are no provider networks, so you can see any doctor or hospital nationwide that accepts Medicare. You typically don’t need referrals to see specialists, making Medigap especially appealing for people who travel frequently or want maximum freedom in choosing healthcare providers.
Medigap plans require a monthly premium, which is generally higher than many Medicare Advantage plans. However, in return, you often have little to no out-of-pocket costs when receiving care. Medigap policies do not include prescription drug coverage, so you’ll need to enroll in a separate Medicare Part D plan. They also don’t typically cover extras like dental, vision, or hearing services.
The best time to enroll in a Medigap plan is during your Medigap Open Enrollment Period, which begins when you’re 65 or older and enrolled in Medicare Part B. During this time, you have guaranteed issue rights, meaning insurance companies cannot deny you coverage or charge higher premiums due to health conditions. Applying outside this window may require medical underwriting.
Medigap can be a strong choice for people who value predictable healthcare costs, nationwide provider access, and long-term stability. It’s often a good fit for those with ongoing medical needs or anyone who prefers fewer billing surprises.
Because Medigap plans work closely with Original Medicare, comparing plan options with a licensed Medicare agent can help you choose the coverage that best fits your health needs, budget, and future plans.
