What is Medicare Supplement(Medigap) Insurance?
Confused about Medicare Supplement Insurance or Medigap? You're not alone.
Original Medicare provides important healthcare coverage, but it doesn't pay for everything. Depending on your situation, you may still have deductibles, coinsurance, and copayments to pay.
That's where Medicare Supplement Insurance, also called Medigap, comes in.
A Medigap policy is private insurance designed to help pay some of the healthcare costs that Original Medicare doesn't fully cover. Understanding how Medigap works—and how it differs from Medicare Advantage—can help you make a more informed decision about your Medicare coverage.
If you're approaching Medicare eligibility or wondering whether a Medicare Supplement plan may be right for you, you don't have to sort through all the options on your own.
As an independent Health & Medicare Insurance Agent, I can help you understand your options and compare available Medicare Supplement plans based on your individual needs.
What Is Medigap?
Medigap is another name for Medicare Supplement Insurance.
Medigap policies are sold by private insurance companies and work alongside Original Medicare (Part A and Part B)to help cover certain out-of-pocket healthcare costs.
Depending on the Medigap plan you choose, it may help pay for things such as:
Part A and Part B coinsurance
Copayments
Certain deductibles
Other Medicare-covered cost-sharing
Certain emergency healthcare costs while traveling outside the U.S., depending on the plan
Medigap does not replace Original Medicare. Instead, Medicare pays its share of an approved covered healthcare service first, and then your Medigap policy may pay its share according to the plan's benefits.
Why Does Medigap Matter?
One reason people consider Medicare Supplement Insurance is to make their healthcare costs more predictable.
Original Medicare doesn't have a yearly out-of-pocket maximum. Having supplemental coverage such as Medigap can help cover certain costs that would otherwise come out of your pocket.
However, Medigap policies don't cover everything. For example, they generally don't cover long-term care, routine vision or dental care, hearing aids, eyeglasses, or prescription drugs.
Medigap vs. Medicare Advantage: What's the Difference?
This is one of the most common Medicare questions I hear.
Medigap and Medicare Advantage are not the same thing.
Medicare Supplement Insurance (Medigap)
Medigap works with Original Medicare.
You generally must have Medicare Part A and Part B to purchase a Medigap policy. You pay a separate Medigap premium to a private insurance company in addition to your Medicare Part B premium.
Medicare Advantage is an alternative way to receive your Medicare benefits through a Medicare-approved private insurance plan.
You generally can't have a Medigap policy and a Medicare Advantage Plan at the same time. Medigap doesn't pay Medicare Advantage copayments, deductibles, or premiums.
The choice between Original Medicare with supplemental coverage and Medicare Advantage depends on your individual circumstances, healthcare needs, providers, medications, budget, and preferences.
There isn't one Medicare option that's right for everyone.
8 Important Things to Know About Medigap
1. You generally need Medicare Part A and Part B
To purchase a Medigap policy, you generally must have both Medicare Part A and Medicare Part B.
If you're approaching 65, it's important to understand your Medicare enrollment timeline before making decisions about supplemental coverage.
2. Medigap is different from Medicare Advantage
This distinction is important.
Medigap supplements Original Medicare. Medicare Advantage is another way to receive your Medicare benefits.
If you're trying to decide between the two, understanding how each type of coverage works—including premiums, cost-sharing, provider access, and additional benefits—can help you determine which option fits your situation.
3. You pay a separate Medigap premium
When you have Medigap, you'll generally pay:
Your Medicare Part B premium to Medicare
Your Medigap premium to the private insurance company
Medigap premiums can vary between insurance companies, even for standardized plans with the same letter.
That's one reason comparing available Medigap policies can be worthwhile.
4. A Medigap policy covers one person
Medigap policies are individual policies.
If you and your spouse both want Medicare Supplement Insurance, each person needs their own Medigap policy.
Your healthcare needs and available options may also be different from your spouse's.
5. Medigap plans are standardized
In most states, Medigap plans are standardized and identified by letters, such as Plan G, Plan K, or Plan N.
Generally, plans with the same letter offer the same basic benefits regardless of which insurance company sells the policy. However, premiums can differ between companies.
This makes it important to look at more than just the insurance company's name when comparing Medigap options.
6. Medigap policies are generally guaranteed renewable
Once you have a Medigap policy, it is generally automatically renewed each year as long as you continue paying your premiums.
A Medigap insurance company generally can't cancel your policy because you develop health problems. There are limited circumstances under which coverage can end, such as failing to pay premiums or certain issues involving the application.
7. Medigap does not include prescription drug coverage
Medigap policies sold after 2005 don't include prescription drug coverage.
If you want Medicare prescription drug coverage, you can generally enroll in a separate Medicare Part D prescription drug plan.
This is an important piece to consider when putting your overall Medicare coverage together.
8. You can't use Medigap with Medicare Advantage
If you're enrolled in a Medicare Advantage Plan, you generally can't purchase a Medigap policy to cover your Medicare Advantage costs.
If you're considering switching from Medicare Advantage to Original Medicare and purchasing Medigap, timing matters. Depending on your circumstances, you may have specific rights to purchase a Medigap policy.
When Is the Best Time to Buy a Medigap Plan?
Timing can be especially important when purchasing Medicare Supplement Insurance.
Your Medigap Open Enrollment Period is a one-time six-month period that begins when you're both 65 or older and enrolled in Medicare Part B.
During this period, you generally have more rights when purchasing a Medigap policy. After this period, your ability to purchase certain Medigap policies may be more limited, and the cost may be higher depending on your circumstances and state rules.
There are also certain situations where you may have guaranteed issue rights, allowing you to purchase Medigap coverage without medical underwriting.
Because these situations can be complicated, it's important to understand your specific circumstances before dropping existing coverage or changing Medicare plans.
How Do I Choose a Medigap Plan?
Choosing a Medicare Supplement plan isn't necessarily about finding the plan with the lowest premium.
You may want to consider:
✓ Your healthcare needs✓ Your expected medical expenses✓ Your preferred doctors and providers✓ Your budget✓ Monthly premiums✓ Out-of-pocket costs✓ Travel plans✓ Prescription drug coverage✓ Your Medigap enrollment period and rights
Because standardized Medigap plans with the same letter generally provide the same basic benefits, the insurance company's premium and other policy details can be important when comparing options.
