What is Medicare Advantage? (2025 Coverage Explained)

Updated Aug 2025

What is Medicare Advantage? Should you choose an Advantage plan over Original Medicare? If you’re eligible for Medicare, these are important questions to ask.

What is Medicare Advantage

Medicare Advantage plans include all the same coverage as traditional Medicare but with additional benefits, like dental, vision, and prescription drug coverage. It’s one of the cheaper health plan options, but you could have higher deductibles or be limited to a specific network of providers. 

Keep reading to learn how Medicare Advantage works. We’re here to explain what Medicare Advantage is and what it covers.  Then use our free comparison tool to find affordable Medicare Advantage plans near you.

Quick Overview

  • There are four types of Medicare Advantage Plans
  • All Advantage plans include Original Medicare Part A and Part B coverage
  • Most Medicare Advantage plans include Part D prescription coverage

How Medicare Advantage Works

Medicare Advantage is still Medicare, but policies are provided by local insurance companies. You can sign up for Medicare Advantage starting three months before you turn 65. 

Medicare Advantage Defined: What is Medicare Advantage?

Most Medicare Advantage plans include Medicare Part D. You don’t need to buy it separately if you choose an Advantage plan that already includes coverage for prescription drugs.

What Medicare Advantage Covers

What is Medicare Advantage vs. Medicare? Medicare Advantage plans cover exactly what Original Medicare Part A and Part B cover. That means your hospital insurance and medical equipment costs are completely or partially covered by Medicare Advantage.

What is Medicare Advantage? Medicare Part A and Part B coverage

Medicare Advantage insurance goes beyond traditional coverage. For instance, most Advantage plans cover prescriptions, helping beneficiaries save money on Part D insurance. You can also pick from plans that provide dental and vision coverage, pay for gym memberships, and cover hearing aids.

Unlike Original Medicare, Medicare Advantage has annual out-of-pocket limits on Parts A and B. Once you reach that limit, you pay nothing for the rest of the year.

The only things Medicare Advantage will not cover are clinical trials and kidney transplants. Hospice coverage may also be limited depending on the plan you choose.

Different Types of Medicare Advantage Plans

Medicare Advantage Part C plans are varied, and coverage options won’t be the same with every company. Determine what type of Medicare Advantage plan you’re interested in and start comparing health insurance plans from multiple companies to get the best rates.

What is Medicare Advantage? list of Medicare advantage plans

Most people opt for an HMO or PPO, but you may want a different type of plan. Scroll down to explore these plans more in-depth.

Health Maintenance Organization (HMO)

HMO plans provide coverage through an in-network of physicians and facilities, and you need referrals from a primary care doctor before visiting any specialists. Getting any medical care out-of-network costs more.

You won’t have the freedom to visit any hospital or doctor you want with an HMO.

HMOs are the most popular plan but work best for people who don’t travel and live in a region with a convenient network of participating physicians. Enter your ZIP code to find affordable providers in your area.

Preferred Provider Organization (PPO)

PPOs also have an organization of in-network providers, but these plans still cover any out-of-network doctors or hospitals that accept Medicare.

You still pay more to use out-of-network physicians with a PPO, but costs are much cheaper than with an HMO.

This type of plan is best for people who have a favorite doctor, specialist, or facility that may not be included in the network.

Private Fee-for-Service (PFFS)

Fee-for-service plans come with predetermined amounts regarding what the provider will pay versus what you’ll pay for different procedures.

With PFFS, you’re allowed to see any doctor or hospital that accepts Medicare, and you get to see your medical costs upfront.

However, doctors and hospitals decide on a case-by-case basis whether to accept a PFFS plan or not, so verify if your physician accepts your plan’s terms before receiving any kind of care.

Special Needs Plans (SNPs)

SNPs aren’t available to everyone. Only beneficiaries in institutional care or those who have chronic or critical conditions can enroll.

In some states, beneficiaries who qualify for Medicaid can sign up for SNPs.

You can switch plans whenever you become eligible as you’ll qualify for a special enrollment period. Learn the difference between Medicare vs. Medicaid plans.

Comparing Medicare Advantage Costs

Medicare insurance costs start at $174/mo but start to increase if you add additional plans or benefits. Medicare Advantage rates are affordable but vary by company.

Medicare Costs by Plan Type
Medicare PlanMonthly PremiumAnnual DeductibleOut-of-Pocket Max
Part A$0-$505$1,632N/A
Part B$174$240N/A
Part C$0-$200$0-$200$8,850
Part D$34$0-$545$2,000
Medigap$35-$488$0-$2,800$3,500-$7,500

If you choose an Advantage Plan, Medicare pays a set amount to your provider for coverage. You’re still responsible for any out-of-pocket costs, including deductibles and monthly premiums. 

Medicare Advantage vs. Original Medicare

The biggest difference between Medicare Advantage vs. Original Medicare is that Advantage plans go beyond just the traditional Part A and B coverage to provide more comprehensive care.

Here are more ways Medicare Advantage is different from Original Medicare:

  • Flexibility and Benefits: Medicare Advantage offers various plan types with extra benefits like dental, vision, and wellness programs. Original Medicare does not.
  • Provider Networks: Some Medicare Advantage plans restrict healthcare to a specific network, but Original Medicare is accepted anywhere that accepts Medicare.
  • Costs: Medicare Advantage deductibles are higher, but plans often have lower premiums and annual out-of-pocket maximums, while Original Medicare has no out-of-pocket maximum, potentially leading to higher costs.
  • Prescription Drugs: Original Medicare doesn’t include prescription drugs, so you need to sign up for Medicare Part D when most Advantage plans include prescription coverage.
  • Referrals: Some Medicare Advantage plans require referrals for specialist services, but Original Medicare does not require referrals if the facilities accept Medicare.

Medicare Advantage also covers more than Medicare Supplemental Insurance (Medigap), as you’ll see below.

Medicare Advantage vs. Medicare Supplement Plans (Medigap)

Medicare Advantage plans often provide the same coverage as a Medigap plan, but Advantage policies are comprehensive while Medigap is only supplemental. 

What is Medicare Advantage? Medicare Advantage vs. Medigap

Medicare Advantage combines Original Medicare coverage with different additional benefits into one single policy. Medigap is not a standalone policy, so you must sign up for Original Medicare first.

Your Advantage plan might limit you to a specific physician network, but you’ll get more benefits at a better price than with Medigap. Medigap plans are a better fit for people who travel or want more access to doctors and hospitals of their choice. 

You cannot have Medigap and Medicare Advantage at the same time. Medigap is only available with Original Medicare.

Medicare Advantage Plan Overview

What is Medicare Advantage? Medicare Advantage combines Parts A and B coverage with additional benefits like dental, vision, and prescription drug coverage.

Advantage plans often feature lower premiums but higher deductibles compared to Original Medicare. They also generally include prescription drug coverage, which can eliminate the need for separate Medicare Part D policies.

However, some people may wonder why Medicare Advantage plans are bad. For instance, Medicare Advantage plans for seniors restrict healthcare access to a network of providers and require referrals for specialists:

  • Health Maintenance Organizations (HMOs): Require in-network care and referrals for specialists, making them ideal for those who do not travel often and prefer a consistent network of providers. 
  • Preferred Provider Organizations (PPOs): Offer more flexibility by covering out-of-network care at a higher cost, suitable for those who want to maintain relationships with specific doctors or facilities. 
  • Private Fee-for-Service (PFFS) plans: Provide clear upfront costs and allow visits to any Medicare-accepting doctor or hospital, though acceptance of the plan can vary by provider.
  • Special Needs Plans (SNPs): Tailored for beneficiaries with specific conditions or circumstances, such as chronic illnesses or institutional care, and offer continuous enrollment options for eligible individuals.

These plans are provided by private insurance companies. Health plan options and availability will vary based on where you live. Enter your ZIP code to find Medicare Advantage companies near you.
