Learn the difference between Medicare Advantage and Medigap to find the best plan for your health care needs.

If Medicare won’t cover all your healthcare needs, Medicare Advantage and Medigap can help. Both Medicare Advantage and Medigap supplement original Medicare to provide more coverage, but there are some important differences between the two.

What is Medicare Advantage?

Medicare Advantage is private health insurance through Medicare that often also includes prescription drug coverage, or Medicare Part D. The plans usually provide coverage for things like vision, dental, disability services, home health, and other health care needs not covered by original Medicare.

“Medicare Advantage plans offer the convenience of providing all of these services in one plan,” Erin Nance, MD, a New York City-based orthopedic surgeon, tells WebMD Connect to Care. “The costs and coverage details vary depending on the specific insurance company and what state you live in.”

Medicare Advantage plans can be HMOs, PPOs, Special Needs Plans (SNPs), private fee-for-service (PFFS) plans, or Medical Savings Account (MSA) plans.

While Medicare Advantage patients don’t need referrals to see a specialist, there are some limits when it comes to providers.

“There are different types of Medicare Advantage Plans that may limit your ability to see a certain provider,” Nance says. “The vast majority of doctors accept Original Medicare and the Medigap supplemental insurance.”

What is Medigap?

Medigap, also known as Medicare Supplement Insurance, adds to original Medicare by filling in gaps where you aren’t covered. Medigap plans usually don’t cover vision, hearing, long-term care or at-home care. However, they're useful for specific types of coverage, such as health insurance while traveling or frequent emergency care.

For instance, under Medigap plan N, foreign emergencies and hospital visits are covered, while emergency visits cost $50. Medigap plan F, a more expensive plan, pays for Part B deductibles while covering the 20% cost of services Medicare doesn’t pay.

Medigap plans do not provide prescription drug coverage, and Medigap cannot be combined with Medicare Advantage. But Medigap plans are a way to tweak your Medicare to your specific situation while covering larger expenses.

Which one is better?

Both Medicare Advantage and Medigap provide advantages and disadvantages.

Some advantages of Medicare Advantage include:

  • More coverage and benefits, which can include services like gym memberships, long-term care, and disability equipment
  • Lower premiums
  • An all-in-one plan which covers Medicare Part A, B, and D 

Some disadvantages of Medicare Advantage include:

  • Having to make sure your preferred provider is in your plan
  • No coverage while traveling
  • A likelihood of higher out-of-pocket and emergency costs

Some advantages of Medigap plans include:

  • Fewer out-of-pocket expenses
  • Access to all providers who accept Medicare
  • Coverage while traveling overseas

Some disadvantages of Medigap plans include:

  • Higher monthly premiums
  • Having to navigate the different types of plans
  • No prescription coverage (which you can purchase through Plan D)

How do you decide?

“Make sure you have enough coverage to limit your financial liability in case of catastrophic injuries or disease,” Nance says. “While the plans that have better benefits often cost more, they will usually save you in the long run in terms of out-of-pocket fees.” Nance further recommends speaking to family and friends to compare experiences.

There are different ways that you can receive your Medicare coverage, or add onto that coverage. Medicare Advantage and Medicare Supplement insurance are options that may sound similar, but they’re quite different. They do have one main thing in common: they’re both offered by private insurance companies.

What is the difference? Medicare Advantage vs Medigap

There are two options commonly used to replace or supplement Original Medicare. One option, called Medicare Advantage plans, are an alternative way to get Original Medicare. The other option, Medicare Supplement (or  Medigap) insurance plans work alongside your Original Medicare coverage. These plans have significant differences when it comes to costs, benefits, and how they work. It’s important to understand these differences as you review your Medicare coverage options.

Original Medicare, Part A and Part B, is a government health insurance program for those who qualify by age or disability. Part A is hospital insurance, and Part B is medical insurance. There are some out-of-pocket costs associated with Original Medicare, such as copayments, coinsurance, and deductibles. To help with those costs, if you’re enrolled in Original Medicare, you can purchase a Medicare Supplement (Medigap) insurance plan.

Medicare Advantage plans offer an alternative way to receive your Medicare benefits through a private, Medicare-approved insurance company. They must include all your Medicare Part A and Part B coverage (except hospice care, which is covered under Medicare Part A), but may offer additional benefits not included in Original Medicare.

You generally cannot enroll in both a Medicare Advantage plan and a Medigap plan at the same time.

What are Medicare Advantage plans?

If you have a Medicare Advantage plan, you’re still enrolled in the Medicare program; in fact, you must sign up for Medicare Part A and Part B to be eligible for a Medicare Advantage plan. The Medicare Advantage plan administers your benefits to you. Depending on the plan, Medicare Advantage can offer additional benefits beyond your Part A and Part B benefits, such as routine dental, vision, and hearing services, and even prescription drug coverage.

There are many different types of Medicare Advantage plans, described below:

  • Health Maintenance Organizations (HMOs) require you to use health-care providers in a designated plan network and may require referrals from a primary care physician in order to see a specialist.
  • Preferred Provider Organizations (PPOs) recommend the use of “preferred” health-care providers in an established network, and these plans are likely to cover more of your medical costs if you stay inside that network. You don’t need a referral to see a specialist.
  • Private Fee-for-Service (PFFS) plans determine how much they will pay health-care providers, and how much the beneficiary is responsible to cover out-of-pocket.
  • Medical Savings Account (MSA) plans deposit money into a “health-care checking account” that you use to pay for health-care costs before the deductible is met.
  • Special Needs Plans (SNP) are tailored health insurance plans designed for beneficiaries with certain health conditions.

If you decide to sign up for a Medicare Advantage plan, you may want to shop around, because costs and coverage details are likely to vary. Our obligation-free eHealthMedicare plan finder tool on this page lets you see all available Medicare Advantage options in your area, including a list of coverage details once you click on the plan of interest.

Some of the costs associated with Medicare Advantage might include a monthly premium (not counting your Part B premium, which you must continue to pay as well), annual deductible, coinsurance, and copayments.

To be eligible to enroll in a Medicare Advantage plan, you must be enrolled in Original Medicare, reside in the plan’s service area, and (in most cases) not have end-stage renal disease (ESRD).

What are Medicare Supplement insurance plans?

Medicare Supplement insurance, also known as Medigap or MedSup, is also sold through private insurance companies, but it is not comprehensive medical coverage. Instead, Medigap functions as supplemental coverage to Original Medicare. Current Medigap plans don’t include prescription drug coverage.

Medigap plans may cover costs like Medicare coinsurance and copayments, deductibles, and emergency medical care while traveling outside of the United States. There are 10 standardized plan types in 47 states, each given a lettered designation (Plan G, for example). Plans of the same letter offer the same benefits regardless of where you purchase your plan. Massachusetts, Minnesota, and Wisconsin offer their own standardized Medigap plans.

The standardized Medigap plans each cover certain Medicare out-of-pocket costs to at least some degree. Every Medigap plan covers up to one year of Medicare Part A coinsurance and hospital costs after Medicare benefits are used up. But, for example, Medigap Plan G plans don’t cover your Medicare Part B deductible, while Medigap Plan C plans do. So, if you’d like to enroll in a Medicare Supplement insurance plan, you might want to compare the Medigap policies carefully.

While benefits are standardized, the costs are not, meaning they could fluctuate depending on the insurance company offering the plan and location. That is, while Medigap Plan G includes the same coverage no matter where you buy it, the premium for this plan can vary. Also, not every standardized lettered plan is offered in every state.

If you decide to sign up for a Medigap policy, a good time to do so is during the Medigap Open Enrollment Period, a six-month period that typically starts the month you turn 65 and have Medicare Part B. If you enroll in a Medigap plan during this period, you can’t be turned down or charged more because of any health conditions. But if you apply for a Medigap plan later on, you may be subject to medical underwriting; your acceptance into a plan isn’t guaranteed.

No matter whether you enroll in a Medigap policy or a Medicare Advantage plan, you must continue paying your Part B premium.

What is the biggest disadvantage of Medicare Advantage?

The biggest disadvantage of Medicare Advantage plans is the closed provider networks, limiting your choice of which doctor or medical facility to use. Medicare Advantage costs are also largely based on how much medical care you need, making it more difficult to budget for health care costs.

Do I need a Medicare Supplement if I have an advantage plan?

You can't buy (and don't need) Medigap while you're in a Medicare Advantage Plan. You can't use Medigap to pay for any costs ( copayments , deductibles , and premiums ) you have under a Medicare Advantage Plan.

Is Medicare Supplement the same as Medicare Advantage?

You must have Medicare Part A and Part B. A Medigap policy is different from a Medicare Advantage Plan. Those plans are ways to get Medicare benefits, while a Medigap policy only supplements your Original Medicare benefits. You pay the private insurance company a monthly premium for your Medigap policy.

Which is better a Supplement or Advantage plan?

A Medicare Advantage plan may be a better choice if it has an out-of-pocket maximum that protects you from huge bills. Regular Medicare plus a Medigap insurance plan generally allows you more choice in where you receive your care.
