Medicare Supplement Plans: How Medigap Works
Medicare Supplement Insurance, also called Medigap, helps pay certain out-of-pocket costs left by Original Medicare.
For many people, Medigap is appealing because it can make health care costs more predictable.
Medicare says Medigap is extra insurance sold by private companies to help pay your share of costs in Original Medicare, such as copayments, coinsurance, and deductibles.
Who Can Buy a Medigap Policy?
Generally, you need Original Medicare Part A and Part B to buy a Medigap policy.
Medigap works with Original Medicare. It is not the same as Medicare Advantage.
This matters because you generally cannot use Medigap to pay Medicare Advantage plan costs.
What Does Medigap Cover?
Medigap policies may help with costs such as:
Part A coinsurance
Part B coinsurance or copayments
Blood costs
Skilled nursing facility coinsurance
Part A deductible
Foreign travel emergency coverage, depending on plan
Out-of-pocket gaps in Original Medicare
Coverage depends on the specific plan letter.
Medicare provides a comparison chart showing what different Medigap plan letters cover.
Medigap Plan Letters
Medigap plans are standardized by letter in most states.
Common plan letters include:
Plan A
Plan B
Plan D
Plan G
Plan K
Plan L
Plan M
Plan N
The benefits for a plan letter are standardized, but prices can differ by insurance company.
For example, Plan G benefits are generally the same standard benefits regardless of company, but premium pricing and service may vary.
Medigap vs. Medicare Advantage
This is a major decision.
Medigap Works With Original Medicare
You keep Original Medicare and add Medigap to help with out-of-pocket costs. You may also buy a separate Part D plan for prescriptions.
Medicare Advantage Replaces How You Receive Medicare Benefits
Medicare Advantage plans are private plans that provide Part A and Part B benefits as an alternative to Original Medicare.
The choice affects doctor access, network rules, drug coverage, monthly premiums, and out-of-pocket costs.
When Is the Best Time to Buy Medigap?
Medicare says your federal Medigap Open Enrollment Period lasts 6 months and starts the first month you have Medicare Part B and are 65 or older. During this period, you have important rights when buying Medigap.
If you apply later, medical underwriting may apply in many situations, depending on your state and circumstances.

Final Thoughts
Medicare Supplement plans can help reduce the financial gaps in Original Medicare.

Before buying, compare plan letters, prices, Part D needs, and long-term affordability.
