Medicare Advantage (Part C) is a type of health insurance plan offered by private insurers approved by CMS that covers all benefits of Original Medicare Part A and Part B, typically adds Part D prescription drug coverage and often bundles extras such as dental, vision and hearing that Original Medicare excludes. CMS pays a fixed monthly amount per enrolled beneficiary to the private insurer, which then manages coverage.

Key Takeaways
Medicare Advantage pros and cons center on one trade-off, extra benefits for narrower provider access.
Most Medicare Advantage plans carry a $0 monthly premium, but the 2026 in-network out-of-pocket maximum reaches $9,250.
Medicare Advantage and Medigap policies can't be used together, they're mutually exclusive by federal rule.
What Is Medicare Advantage?
What Are the Pros of Medicare Advantage?
Medicare Advantage plans carry real coverage advantages over Original Medicare, particularly for beneficiaries who want capped annual costs and bundled extras without buying multiple standalone policies. The most cited benefit is the $0 monthly Part C premium available on most plans in 2026, on top of the standard Part B premium of $202.90 per month. Medicare Advantage also adds an annual out-of-pocket maximum, which Original Medicare does not provide, giving enrollees a defined ceiling on medical spending each year.
$0 Monthly Premiums on Most Plans
Most Medicare Advantage plans charge $0/month in Part C premiums. Enrollees pay only the standard $202.90/month Part B premium in 2026, compared to an additional $100 to $200/month for a Medigap policy.
An Out-of-Pocket Maximum Original Medicare Lacks
Medicare Advantage caps in-network costs at $9,250 in 2026, per CMS. Original Medicare has no equivalent ceiling, leaving beneficiaries with unlimited liability for a hospitalization without supplemental coverage.
Dental, Vision and Hearing Coverage Bundled In
Original Medicare excludes routine dental, eyeglasses and hearing aids. Many Medicare Advantage HMO plans include up to several hundred to over a thousand dollars in annual dental cover benefits, depending on the plan, letting enrollees often recover any plan premium cost through these extras alone.
Part D Drug Coverage Included in Most Plans
Most Medicare Advantage plans bundle Part D as MA-PD plans, eliminating the need for a standalone drug plan. Beneficiaries should still verify their specific medications appear on the plan's formulary at a preferred tier before enrolling.
Extra Benefits Not Available in Original Medicare
Many plans include fitness memberships, telehealth visits, meal delivery after hospitalization and medical transportation. These extras are not standardized, availability and dollar limits differ by insurer and county, so reviewing the Evidence of Coverage document before enrolling is important.
What Are the Cons of Medicare Advantage?
Medicare Advantage plans restrict where and from whom you can receive care and that restriction is the central drawback. The limitation affects a predictable set of beneficiary profiles most severely: those with long-standing specialist relationships outside a local HMO network, frequent travelers and those managing chronic conditions that require multiple specialists. For all three groups, the administrative friction and cost exposure that accompany most Medicare Advantage plans can offset the premium savings and extra benefits.
Network Restrictions Limit Provider Choice
Prior Authorization Delays Many Services
Medicare Advantage requires prior authorization for procedures, specialist referrals and post-acute care that Original Medicare covers without advance approval.
No Medigap Pairing Allowed by Federal Rule
Federal law prohibits pairing a Medigap policy with Medicare Advantage. Beneficiaries who want gap-filling cost protection must disenroll from Medicare Advantage and return to Original Medicare first.
Plan Benefits and Networks Change Every Year
Premiums, formularies, provider networks and copays can all change each January 1. CMS requires an Annual Notice of Change by September 30, but a plan that covered your doctors in 2025 may restructure its network or formulary in 2026 without warning.
Switching Back to Original Medicare Carries Risk
Leaving Medicare Advantage for Medigap, triggers underwriting in most states, where insurers can deny coverage or charge more based on health status. Only Connecticut, Maine, Massachusetts and New York guarantee year-round Medigap issue rights, making the initial enrollment decision consequential.
Who Should Consider Original Medicare Instead
Beneficiaries who prioritize unrestricted provider access and travel flexibility may find Original Medicare with Medigap Plan G or Plan N more predictable. Plan G averages $100 to $200/month for a 65-year-old depending on state and insurer.
How Does Medicare Advantage Compare to Original Medicare?
Medicare Advantage and Original Medicare cover the same core Part A and Part B benefits, but they differ on cost structure, access rules, and added coverage. The most important axis isn't monthly premium but total annual exposure: Original Medicare has no out-of-pocket maximum, while Medicare Advantage caps in-network costs at $9,250 in 2026, per CMS.
Feature | Medicare Advantage | Original Medicare |
|---|---|---|
Monthly premium | $0 to $50/month (Part C) plus $202.90/month Part B in 2026 | $202.90/month Part B in 2026, no Part C |
Provider network | Contracted network (HMO) or tiered network (PPO) | Any provider accepting Medicare assignment nationwide |
Prior authorization | Required for many procedures, referrals and post-acute care | Not required for covered services |
$9,250 in-network cap in 2026, per CMS | No out-of-pocket maximum | |
Dental, vision, hearing | Typically included with annual benefit limits | Not covered |
Prescription drug coverage | Usually bundled (MA-PD plans) | Not included, requires separate Part D plan |
Medigap compatibility | Not permitted by federal rule | Fully compatible |
Plan availability | Varies by county, not available in all areas | Available nationwide to all Medicare-eligible beneficiaries |
One consequence the table doesn't capture is timing. Beneficiaries who enroll in Medicare Advantage at 65 and later return to Original Medicare will face Medigap underwriting in most states, where insurers can deny coverage or charge more based on health status. That downstream risk makes the initial Medicare Advantage enrollment decision more consequential than a monthly premium comparison alone suggests. Beneficiaries should evaluate long-term switching costs before selecting a plan at initial eligibility.
What Should You Consider Before Choosing a Medicare Advantage Plan?
Choosing between Medicare Advantage and Original Medicare carries long-term consequences, especially if you later want a Medigap policy. The right evaluation goes beyond the monthly premium. Network depth, formulary tier placement for your specific prescriptions, CMS star ratings and a plan's prior authorization footprint all affect how much your coverage actually costs in a given year. Not all of those factors are visible from a premium comparison alone, which is why reviewing each dimension before the Annual Enrollment Period (October 15 to December 7) is important.
Consideration | What to Check | Key Detail |
|---|---|---|
Provider network | Whether your current doctors and preferred hospital are in-network | Confirm on Medicare Plan Finder or the insurer's provider directory before enrolling |
Drug formulary | Whether your prescriptions appear at a preferred tier | Formularies change annually, verify at each Annual Enrollment Period (Oct. 15 to Dec. 7) |
CMS star rating | Plan quality score from CMS (1 to 5 stars) | 4 stars or higher indicates above-average member experience and care coordination |
Out-of-pocket maximum | The plan's annual cap on in-network costs | Cannot exceed $9,250 for in-network costs in 2026, per CMS |
Prior authorization requirements | Which services require advance approval | Plans with broader prior authorization lists create more friction for specialist care |
Service area stability | Whether you spend significant time in another state | HMO plans don't cover out-of-area non-emergency care, PPO plans charge higher out-of-network rates |
Annual Enrollment Period timing | October 15 to December 7 each year | Changes take effect January 1 |
Medigap re-enrollment risk | Whether you might want to switch back to Original Medicare later | Most states allow insurers to deny Medigap coverage based on health status after initial eligibility |
Who Benefits Most From Medicare Advantage?
Beneficiaries whose primary concern is premium cost or who want dental and vision coverage without buying separate standalone policies, get the clearest benefit from Medicare Advantage.
A $0 premium Medicare Advantage plan with bundled dental, vision and Part D can cost meaningfully less per month than Original Medicare paired with a standalone Part D plan and a Medigap policy. Medicare Advantage is generally a stronger fit for beneficiaries who live in one service area year-round, have primary care relationships within a local HMO or PPO network and don't require frequent out-of-network specialist access.
Is Medicare Advantage Worth It? The Bottom Line
Medicare Advantage works best for beneficiaries who want bundled dental, vision, and drug coverage at a $0 premium and don't rely on out-of-network specialists. The 2026 in-network out-of-pocket cap of $9,250, per CMS, gives cost certainty that Original Medicare doesn't provide. Beneficiaries who travel frequently, manage complex conditions requiring multiple specialists or anticipate wanting a Medigap policy later will likely find Original Medicare with a Medigap plan to be the stronger fit. The enrollment decision at age 65 carries long-term consequences because Medigap underwriting protections don't apply in most states after initial eligibility.
Medicare Advantage Pros and Cons: FAQ
We've covered the most frequently asked questions about Medicare Advantage pros and cons related to costs, network limits, enrollment rules and switching risks:
Can you use a Medigap policy with Medicare Advantage?
Federal rules bar pairing a Medicare Supplement (Medigap) policy with Medicare Advantage. The two coverage types are mutually exclusive. Disenrolling from Medicare Advantage and returning to Original Medicare is required before a Medigap policy can take effect.
What happens to your Medicare Advantage coverage if you move to a new state?
Medicare Advantage plans are sold by county, so a plan in your current county may not exist in your destination. CMS requires plans to cover emergencies nationwide, but non-emergency out-of-area care is not covered on most HMO plans.
Does Medicare Advantage cover care outside the United States?
Original Medicare generally does not cover care abroad and most Medicare Advantage plans follow the same rule. A small number of plans include limited foreign travel emergency coverage, but it is not a standard benefit. Verifying the Evidence of Coverage document before international travel is the only reliable approach.
How often can you switch from Medicare Advantage back to Original Medicare?
The Annual Enrollment Period (October 15 to December 7) lets you switch between Medicare Advantage and Original Medicare each year, effective January 1. A separate Medicare Advantage Open Enrollment Period (January 1 to March 31) allows one additional switch opportunity.
