“My Medicare Advantage plan is free, so why am I getting a $4,000 bill?” It’s one of the most common questions adult children ask when a parent ends up in the hospital. The confusion is understandable. A $0 monthly premium sounds like free healthcare, but premiums are only one piece of what a Medicare Advantage plan actually costs. Copays, deductibles, and the plan’s out-of-pocket maximum all factor into what a family actually pays over the course of a year. This guide breaks down each of those costs using 2026 CMS figures, explains how the moving pieces fit together, and walks through what a zero-premium plan really means in practice.
What Affects Medicare Advantage Costs
Medicare Advantage (Part C) plans are sold by private insurance companies that contract with the federal government. Because each insurer designs its own plan within CMS guardrails, costs vary significantly from one plan to the next, even within the same county. Several factors shape what a person actually pays:
- Monthly premium: the amount paid to the plan itself, separate from the Medicare Part B premium
- Deductibles: what must be paid out of pocket before certain coverage begins
- Copays and coinsurance: the cost-sharing paid at the time of each service
- Out-of-pocket maximum: the annual cap on total cost-sharing for covered services
- Drug coverage costs: a separate set of costs for plans that include Part D prescription coverage
Understanding each of these pieces, and how they interact, is the key to comparing plans accurately rather than focusing on premium alone.

The Part B Premium: Everyone Pays This First
Before looking at what a Medicare Advantage plan itself charges, it helps to understand the one cost that applies to nearly everyone with Medicare: the Part B premium. Medicare Advantage doesn’t replace this cost. Enrollees continue paying it even if their MA plan has a $0 premium.
- 2026 standard Part B premium: $202.90 per month
- 2026 Part B annual deductible: $283
- Higher-income enrollees pay an Income-Related Monthly Adjustment Amount (IRMAA) on top of the standard premium, based on income reported two years prior
These figures come directly from CMS’s 2026 Medicare Parts A & B premiums and deductibles announcement. Some Medicare Advantage plans offer a partial “Part B premium give-back,” known as a Part B rebate. In 2026, roughly a third of individual MA plans offer some reduction in the Part B premium, though for most enrollees who get one, the reduction is relatively small compared to the full premium. It can be a meaningful perk, but it generally is not the deciding factor between plans.
Medicare Advantage Plan Premiums in 2026
On top of the Part B premium, most Medicare Advantage plans charge a separate monthly premium, though many charge nothing at all. Here’s what the 2026 landscape looks like nationally, according to KFF’s 2026 Medicare Advantage premium analysis:
- Average MA plan premium across all enrollees in 2026: approximately $14 per month
- Roughly three-quarters of enrollees in MA plans with drug coverage pay no premium beyond the standard Part B premium
- Premiums vary widely by plan, insurer, and county. The same insurer may charge $0 in one county and $60 or more in a neighboring county
Premiums are typically the most visible number in MA plan marketing, which is exactly why families need to look past it. A $0 premium and a $60 premium plan can end up costing a family very different amounts over a year, depending on the rest of the cost structure.
Zero-Premium Plans: What “Free” Actually Means
Zero-premium Medicare Advantage plans are widely advertised, and for good reason: they’re genuinely popular and genuinely free of a monthly plan charge. But “free” only refers to the premium. It says nothing about what happens when a person actually needs care.
The Trade-Off Families Should Understand
Insurance companies still need to cover their costs. When a plan doesn’t charge a premium, it typically makes up for that through one or more of the following:
- Higher copays for doctor visits, specialist visits, or hospital stays
- A higher out-of-pocket maximum, meaning more total cost-sharing before the plan covers 100%
- A narrower provider network, which can limit which doctors and hospitals are covered
- More prior authorization requirements for certain services
None of this means zero-premium plans are a poor choice. For a healthy senior who rarely visits the doctor, a $0 premium plan with a higher out-of-pocket maximum may genuinely cost less over the year than a plan with a $50 monthly premium. The math only works against a zero-premium plan in years with significant medical needs, like a hospitalization or a new diagnosis requiring frequent specialist care. The honest answer to “is a zero-premium plan a good deal” is: it depends entirely on how much care gets used that year.
A Tighter Market in 2026
Families comparing plans this year should also know that the zero-premium landscape has shifted. There are 231 fewer $0-premium plans available nationally in 2026 than in 2025, and roughly 2.9 million enrollees were displaced from plans that exited the market and had to choose a new plan for the year. Supplemental benefits in several categories have also grown somewhat leaner as insurers work to restore profitability. None of this means zero-premium options have disappeared. It does mean a parent’s zero-premium plan from last year may not exist this year, which is one more reason to review coverage during open enrollment rather than assume it will auto-renew unchanged.
Copays and Coinsurance: The Costs That Add Up
Copays are where Medicare Advantage diverges most noticeably from Original Medicare in day-to-day experience. Instead of Original Medicare’s standard 20% coinsurance on most Part B services, MA plans typically use a fixed copay structure, similar to commercial insurance.
- Primary care visits commonly carry a copay in the $0 to $40 range, depending on the plan
- Specialist visits typically cost more than primary care, often $30 to $65 per visit
- Emergency room visits often carry a flat copay, frequently in the $90 to $120 range, though this varies significantly by plan
- Hospital inpatient stays are often billed as a daily copay for the first several days, rather than the deductible-based structure used by Original Medicare
These figures vary by plan and should always be checked against a specific plan’s Summary of Benefits rather than assumed. What matters most for families is recognizing that frequent specialist visits, a hospitalization, or an ER visit can generate real costs even on a plan with an appealing premium.
The Out-of-Pocket Maximum: The Number That Matters Most
If there’s one figure families should understand before anything else, it’s the maximum out-of-pocket limit, or MOOP. This is the safety net built into every Medicare Advantage plan, and it’s the single biggest financial advantage MA has over Original Medicare without supplemental coverage.
- 2026 mandatory in-network MOOP limit: $9,250 (a decrease from $9,350 in 2025)
- 2026 combined in-network and out-of-network MOOP limit for plans that allow it (mainly PPOs): $13,900
- Plans may set a lower MOOP than the federal maximum, and many do. The average in-network MOOP across MA enrollees in 2026 is roughly $5,400, well below the cap
- Once the MOOP is reached, the plan pays 100% of covered Part A and Part B costs for the rest of the calendar year
It’s worth being precise about what counts toward the MOOP and what doesn’t. The MOOP applies only to covered Part A and Part B medical services. It does not include monthly premiums, prescription drug costs under Part D, or out-of-network costs on an HMO plan. A family budgeting for a parent’s care should think of the MOOP as the ceiling on medical cost-sharing, not as a ceiling on every dollar that might leave the household that year.
Original Medicare, by contrast, has no out-of-pocket maximum at all. That’s the core reason many people on Original Medicare also carry a Medigap policy.

Putting It Together: A Realistic Cost Comparison
Consider two hypothetical plans available in the same county for 2026, to see how the pieces interact over a year that includes a meaningful health event:
- Plan A: $0 monthly premium, $9,250 in-network MOOP
- Plan B: $55 monthly premium, $3,000 in-network MOOP
In a light-use year with only routine visits, Plan A likely costs less since the family pays no premium and uses little of the cost-sharing structure. But in a year that includes a hospitalization or ongoing specialist care, Plan B’s $660 in annual premiums (12 months at $55) can be the better value, since the family’s total exposure is capped at $3,000 rather than $9,250. There is no universal right answer. The right plan generally depends on the senior’s current health, anticipated care needs for the coming year, and whether their preferred doctors and hospitals are in each plan’s network.
Prior Authorization: A 2026 Update Worth Knowing
Many Medicare Advantage plans require prior authorization, plan approval, before covering certain services, particularly higher-cost care like skilled nursing stays, certain imaging, or specialty procedures. A new CMS rule effective January 1, 2026 changes how this process works:
- Expedited (urgent) prior authorization requests must now receive a decision within 72 hours
- Standard prior authorization requests must now receive a decision within 7 calendar days
- Plans must now provide a specific reason when a request is denied, rather than a generic denial
These changes don’t eliminate prior authorization, and they don’t guarantee a particular outcome. But they do mean families facing a denial or a delay have clearer rules to point to, and a denial letter that should explain, in specific terms, why a request was turned down.
A Bill Families Should Watch, Not Rely On
Families researching Medicare Advantage costs may come across mentions of the Medicare Advantage Improvement Act of 2026 (H.R. 8375). This is introduced legislation, a bill that has not been enacted into law. Its provisions are not yet in effect and may never take effect in their current form. Families should not make coverage decisions based on the assumption that this bill will pass, and should watch for updates from CMS or a SHIP counselor rather than rely on news coverage of proposed legislation.
Questions to Ask Before Choosing a Plan
With premiums, copays, and the out-of-pocket maximum all factoring into the real cost of a plan, these questions can help a family compare options more accurately than premium alone:
- What is this plan’s in-network out-of-pocket maximum, and how does it compare to other plans available in this ZIP code?
- What are the specific copays for primary care, specialist visits, and emergency care?
- Does this plan include a Part B premium rebate, and if so, how much?
- Are this senior’s current doctors, specialists, and preferred hospital in the plan’s network?
- What services on this plan require prior authorization, and what is the plan’s recent track record for approvals?
A SHIP counselor can walk through these questions for free using Medicare’s official Plan Finder, without any sales incentive tied to the outcome.

Frequently Asked Questions
Does Medicare Advantage have a deductible?
It depends on the plan. Some Medicare Advantage plans have no deductible at all, while others apply one before certain services, like a hospital stay, are covered. A plan with no deductible often has a higher monthly premium or higher copays to balance it out. Always check the specific plan’s Summary of Benefits rather than assuming a deductible structure based on another plan or on Original Medicare.
What happens after I hit my out-of-pocket maximum?
Once a person reaches their plan’s in-network maximum out-of-pocket limit for the year, the plan covers 100% of covered Part A and Part B costs for the remainder of that calendar year. This protection resets every January 1. It does not extend to prescription drug costs under Part D, which has its own separate annual cap.
Is a $0 premium Medicare Advantage plan actually free?
The plan itself doesn’t charge a separate premium, but the enrollee still pays the standard Part B premium ($202.90 per month in 2026), and the plan still applies its own copays, coinsurance, and out-of-pocket maximum when care is used. “Free” describes the premium line item only, not the total cost of a year of care.
Can I switch Medicare Advantage plans if the costs turn out to be too high?
Yes, but only during specific windows. The Annual Enrollment Period (October 15 to December 7) is the main opportunity each year, and the Medicare Advantage Open Enrollment Period (January 1 to March 31) allows a one-time switch for those already enrolled in an MA plan. Outside those windows, a change generally requires a qualifying life event. Senioridy’s How to Choose and Switch Medicare Advantage Plans covers these windows and the switching process in detail.
