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.

Medigap Cons

Potential disadvantages include:

Monthly premium

How to Compare Medigap Plans

Compare:

Plan letter benefits
Monthly premium
Rate increase history
Company reputation
Household discounts
Enrollment timing
Customer service
Availability in your state
Whether you need Part D separately

Do not choose only by brand name. Since benefits are standardized by plan letter, price and service matter.

Who May Like Medigap?

Medigap may be a strong fit for people who:

Want provider flexibility
Travel often
Prefer Original Medicare
Want predictable costs
See specialists frequently
Do not want network restrictions
Can afford a monthly premium

Final Thoughts

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

If you want flexibility, predictable cost-sharing, and fewer network concerns, Medigap may be worth comparing. But timing matters, and premiums vary.

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