MEDICARE SUPPLEMENT · MEDIGAP

More freedom to use Medicare providers starts with the right timing.

Medigap can help with some of Original Medicare's out-of-pocket costs. The decision also involves Part D, premiums, your provider preferences and enrollment rights that may not repeat.

A DIRECT ANSWER

How does Medicare Supplement insurance work?

Medicare Supplement insurance is private coverage that supplements Original Medicare. It can help pay some costs that Original Medicare leaves to you, such as certain deductibles, coinsurance and copayments. It is not Medicare Advantage, and it does not replace Part A or Part B.

Because Medigap does not include prescription drug coverage, a complete comparison also checks the separate Part D plan, every prescription and your preferred pharmacies.

Understand Original Medicare costs and gaps

A PRACTICAL PLAN COMPARISON

Plan G and Plan N are commonly compared—but the premium is not the whole answer.

Both are standardized Medicare Supplement plans. The same letter has the same basic benefits regardless of the carrier; the premium and the way the remaining costs fit your priorities still deserve a personal comparison.

MORE COMPLETE OF THESE TWO

Plan G

Plan G is designed for someone who wants more complete protection from Medicare-approved cost-sharing after paying the annual Part B deductible.

Part A deductible, hospital and skilled nursing cost-sharing: covered
Part B coinsurance and excess charges: covered
You still pay: the annual Part B deductible

Often fits: someone who values more predictable Medicare-approved costs.

A DIFFERENT COST-SHARING TRADEOFF

Plan N

Plan N also covers many important Original Medicare cost-sharing exposures, while leaving certain costs with the beneficiary.

Part A deductible, hospital and skilled nursing cost-sharing: covered
Part B coinsurance: covered, except for certain office and emergency-room copays
You still pay: the annual Part B deductible and any applicable Part B excess charges

Often fits: someone comfortable with those tradeoffs when the actual premium comparison makes sense.

Important: Do not assume Plan N is always cheaper than Plan G. In some Southern California markets, the actual premium difference may be small—or Plan N may not be lower. We compare the exact carrier rates, your providers, Part D plan and coverage priorities before recommending a path. Plans C and F are generally not available to people new to Medicare on or after January 1, 2020.

Timing can change the choices available to you

Medigap's main enrollment protection is different from the fall Medicare Annual Enrollment Period.

Your six-month window

Federal Medigap Open Enrollment generally begins the first month you have Part B and are 65 or older. It lasts six months and does not repeat annually.

Health questions can matter later

During that protected period, an insurer cannot use medical underwriting to deny a policy it sells because of a pre-existing condition. Later, the rules can be different.

Guaranteed-issue situations exist

Certain life and coverage changes can create special rights. Confirm the exact situation before leaving a plan or assuming a change is available.

KEEP THE DECISION IN ORDER

Medigap helps with Medicare cost-sharing. Other needs can sit outside that decision.

Original Medicare and a Medicare Supplement policy are the foundation for Medicare-approved care and certain cost-sharing. Routine dental, vision and hearing needs—and the financial impact of a serious diagnosis or recovery—can still be separate coverage conversations.

Medicare-approved costs

Medigap can help with certain deductibles, copayments and coinsurance under Original Medicare. The exact help depends on the lettered policy and the service involved.

Needs outside Medicare

Medicare does not generally include routine adult dental, vision or hearing coverage. Those needs have their own benefits, networks and limits to review.

Protection before a diagnosis

Some coverage is easier to consider before a health event. For people still under 65, California age and eligibility rules can make the timing especially important.

That is why we recommend an Umbrella review after the Medicare foundation is understood. Depending on eligibility and needs, it can include cancer, heart attack and stroke protection, dental, vision and hearing, or other appropriate coverage conversations—without replacing Medicare or Medigap.

Medicare Supplement Questions

Answers to the timing and coverage questions that matter before you choose Medigap.

What is Medicare Supplement insurance?

Medicare Supplement insurance, also called Medigap, is private insurance that works alongside Original Medicare to help pay certain out-of-pocket costs such as deductibles, copayments and coinsurance. You generally need Medicare Part A and Part B to buy it.

Does Medigap include prescription drug coverage?

No. Medigap policies sold after 2005 do not include prescription drug coverage. Someone who wants drug coverage generally needs a separate Medicare Part D plan, so prescriptions and pharmacies remain part of the comparison.

When is the best time to buy a Medigap policy?

Federal Medigap Open Enrollment generally lasts six months, beginning the first month you have Part B and are 65 or older. It is a one-time period. During it, insurers cannot use medical underwriting to deny a policy they sell because of a pre-existing health condition.

Can I buy a Medigap policy later?

Possibly, but outside your protected enrollment period or another guaranteed-issue situation, an insurer may use medical underwriting, charge more or decline an application. Review the timing and your exact rights before you make a change.

Is Medicare Supplement better than Medicare Advantage?

Neither is automatically better. Medigap works with Original Medicare and typically involves a separate Part D plan; Medicare Advantage uses a private plan with its own network, costs and rules. The useful choice depends on doctors, travel, prescriptions, budget and timing.
