Medicare Advantage cost in 2026: what caregivers should know

Short answer

Medicare Advantage costs come in four parts: the Part B premium ($202.90 per month in 2026, paid to Medicare), a plan-specific supplemental premium (averaging $15 per month in 2026, with 75% of enrollees paying $0), point-of-care cost-sharing (deductibles, copays, and coinsurance), and a yearly in-network out-of-pocket maximum ($9,250 in 2026 as the CMS statutory cap). Your actual annual cost depends on how much care you use.

The four cost components caregivers keep confusing

Medicare Advantage cost is not a single number. It has four components, and each one behaves differently. Understanding what each component does is the difference between a realistic budget and a surprise bill.

The Part B premium and the supplemental premium are fixed monthly costs. The cost-sharing kicks in only when care is used. The out-of-pocket maximum is not a cost — it is a cap that limits how much cost-sharing can accumulate in a year for in-network services.

A fifth category sits alongside these four: Part D, Medicare’s prescription drug coverage. Most Medicare Advantage plans bundle Part D drug coverage into the same plan, and the drug-related cost-sharing (drug deductible, tier copays) is separate from the medical cost-sharing above. The 2026 Inflation Reduction Act cap on Part D out-of-pocket drug costs is $2,100, separate from the medical out-of-pocket maximum.

The mistake most caregivers make is looking at only the premium components (which are easy to compare) and skipping the cost-sharing (which is where a bad plan match actually shows up).

The Part B premium is not optional — even with $0 Medicare Advantage

Medicare Advantage plans do not replace the underlying Medicare program. Part A (hospital) and Part B (medical) are still Medicare. The Part B premium is paid to Medicare regardless of whether the person is enrolled in Original Medicare or Medicare Advantage.

In 2026, the standard Part B premium is $202.90 per month. Higher-income beneficiaries pay an additional amount on top of the standard premium — the Income-Related Monthly Adjustment Amount, or IRMAA. The income-related amount is re-set each year based on income reported on tax returns from two years earlier.

The Part A premium is $0 for most Medicare enrollees who worked and paid Medicare taxes for at least 40 quarters (10 years). Enrollees with fewer quarters pay a partial or full Part A premium ($311 or $565 per month in 2026, depending on quarters worked).

The Part B premium is deducted automatically from the Social Security benefit each month when the person is receiving Social Security. If the person is not yet receiving Social Security, Medicare bills the Part B premium directly on a quarterly schedule.

A “$0 premium” Medicare Advantage plan means the plan’s own supplemental premium is $0 — not that the person’s total Medicare cost is $0. The Part B premium is still due.

Medicare Advantage supplemental premium: what “$0 premium” really means

The supplemental premium is what the Medicare Advantage plan carrier charges on top of the Part B premium. In 2026, KFF data shows the average enrollment-weighted supplemental premium is $15 per month across all Medicare Advantage plans that include prescription drug coverage.

That average hides a wide distribution. Roughly 75% of enrollees in Medicare Advantage plans with prescription drug coverage pay $0 in supplemental premium — the plan’s supplemental premium is fully absorbed by the federal rebate the carrier receives for hitting quality and cost benchmarks. The remaining quarter of enrollees pay something above $0, sometimes considerably above.

The trade-off for a $0-premium plan is not free money. In exchange for zero premium, the carrier typically structures the plan with higher cost-sharing at the point of care, tighter networks, or narrower formularies. A $0-premium plan can be an excellent value for a low-utilization enrollee whose providers are all in-network and whose medications are all on the formulary. For a higher-utilization enrollee, the cost-sharing structure can outrun what a small monthly premium would have saved.

The right comparison is not “premium vs premium.” It is “premium plus expected annual cost-sharing vs premium plus expected annual cost-sharing” — for that specific person’s expected utilization.

Deductibles, copays, and coinsurance under Medicare Advantage

Medicare Advantage plans set their own cost-sharing structures within limits set by CMS. Three types of cost-sharing show up on almost every plan:

Deductible: an amount the person pays before the plan starts covering. Medicare Advantage plans may or may not have a medical deductible. When they do, it applies to specific service categories rather than all services. Part D drug coverage inside the plan typically has its own separate deductible.

Copay: a fixed dollar amount the person pays each time a service is used. Copay amounts are set plan by plan and differ by service category — a primary care visit, a specialist visit, and an emergency room visit each usually carry a different copay, and the emergency room copay is usually waived if the person is admitted to the hospital. There is no national standard copay, so the only reliable figures are the ones printed in the specific plan’s Summary of Benefits.

Coinsurance: a percentage of a service’s cost the person pays. Coinsurance is most common on higher-cost services like inpatient hospital stays or Part B drugs administered at a specialist’s office. Because coinsurance is a share of the bill rather than a flat amount, the dollar exposure grows with the cost of the service, and the only thing that caps it is the plan’s in-network out-of-pocket maximum.

Cost-sharing amounts vary widely between plans and even between service categories within the same plan. The Summary of Benefits — required on every Medicare Advantage plan’s marketing materials — lists cost-sharing by service category. The Evidence of Coverage, delivered to enrollees annually, has the complete detail.

The hidden cost driver is prior authorization. When a Medicare Advantage plan denies coverage for a service the doctor recommended, the person can either wait for the appeal process — the CMS-0057-F rule, which applies from 2026, sets timelines of 72 hours for expedited (urgent) requests and 7 calendar days for standard (non-urgent) requests — or pay out of pocket. Denied care that turns into paid-out-of-pocket care does not count toward the in-network out-of-pocket maximum. Baba’s prior authorization rules under CY 2026 walks through how the timelines work and how to escalate when a denial hits.

The in-network out-of-pocket maximum: your risk cap for the year

The in-network out-of-pocket maximum (MOOP) is the cap on how much a Medicare Advantage enrollee can pay in cost-sharing for in-network Part A and Part B services during a calendar year. Once the MOOP is reached, the plan covers the full cost of covered in-network services for the rest of the year.

The 2026 CMS statutory limits:

• $9,250 is the maximum in-network out-of-pocket that any Medicare Advantage plan can set for 2026. A plan can set a lower MOOP, but not higher.
• $13,900 is the maximum combined in-network + out-of-network MOOP for PPO plans.

Real 2026 MA plans set MOOPs below the statutory cap. KFF data shows the average in-network MOOP across all Medicare Advantage plans in 2026 is $5,421 — well below the $9,250 ceiling. For PPO plans, which also cover out-of-network care, the average limit for in-network and out-of-network services combined is $9,825 in 2026.

Two things about MOOP that catch caregivers off guard:

• Prescription drugs have a separate limit. MOOP applies only to Part A and Part B services (medical). Prescription drug cost-sharing under Part D inside the plan has its own separate cap — $2,100 in 2026. A person can hit their medical MOOP and still owe more on Part D drugs.
• Out-of-network services often accumulate to a separate MOOP. In HMO plans, out-of-network care is typically not covered at all outside emergencies. In PPO plans, out-of-network care is covered with higher cost-sharing that accumulates to the combined MOOP, not the in-network MOOP. If a Medicare Advantage enrollee ends up seeing an out-of-network specialist (whether by choice or by referral), the in-network cap does not apply to that care.

For high-utilization years, the MOOP is the single most important number in the plan. It is the dollar amount that separates a manageable year from a financial hardship. When medical bills become unaffordable, the path forward depends on whether the amounts fell inside or outside the MOOP protection.

Total annual cost by utilization scenario

Averages are misleading. What matters is the total-annual-cost estimate for the specific utilization pattern of the specific person. Three scenarios show the range.

Low utilizer

Utilization pattern: a couple of primary care visits per year, one specialist visit, a few maintenance medications on the formulary, no procedures, no hospitalization.

• Part B premium: $202.90 × 12 = $2,434.80 for the year
• Supplemental premium, on a $0-premium plan: $0
• Cost-sharing at point of care: a handful of office-visit copays plus routine prescription copays, nowhere near the plan’s out-of-pocket maximum

For a low utilizer, a $0-premium Medicare Advantage plan often produces the lowest total annual cost among Medicare options: the Part B premium dominates the bill and cost-sharing barely registers. The copay amounts come from the plan’s own Summary of Benefits, which is why a realistic total has to be built plan by plan rather than from an average.

Medium utilizer

Utilization pattern: several primary care and specialist visits, a handful of daily medications across a mix of formulary tiers, one outpatient procedure, one imaging study.

• Part B premium: $2,434.80 for the year
• Supplemental premium: $0 on a $0-premium plan, otherwise the plan’s stated monthly premium
• Cost-sharing: specialist copays, outpatient procedure coinsurance, imaging copays and higher-tier drug copays, accumulating toward the plan’s out-of-pocket maximum without usually reaching it

For a medium utilizer, plans start to differentiate. A plan with a slightly higher supplemental premium but lower specialist copays can cost less overall than a $0-premium plan with steep specialist copays. The comparison requires modelling the specific plan against the specific utilization; an average premium cannot answer it.

High utilizer

Utilization pattern: chronic condition management, frequent specialist visits, many daily medications including high-tier drugs, and an inpatient hospitalization during the year.

• Part B premium: $2,434.80 for the year
• Supplemental premium: $0 on a $0-premium plan, otherwise the plan’s stated monthly premium
• Cost-sharing: reaches the in-network out-of-pocket maximum. On a plan sitting at the 2026 average in-network limit that is $5,421; on a plan sitting at the statutory ceiling it is $9,250. Out-of-network care in a PPO accumulates instead toward the combined limit, which may run as high as $13,900.
• Part D drugs: a further $2,100 at most, because the drug cap is separate from the medical one

For a high utilizer, the plan’s out-of-pocket maximum is the ceiling, and a plan that sets it well below the statutory cap protects better than one that sets it at the cap, even if the monthly premium is higher.

Medicare Advantage vs Original Medicare + Medigap Plan G

Original Medicare covers most Part B services after a $283 annual deductible in 2026 and pays for Part A services with a $1,736 hospital deductible per benefit period. The person pays a 20% coinsurance on most Part B services, plus the deductibles, unless a Medigap policy covers those amounts.

Medigap Plan G is the most comprehensive Medigap policy widely available in 2026 (Plan F is closed to new Medicare enrollees who became eligible on or after January 1, 2020). Plan G covers essentially all Part A and Part B cost-sharing except the annual Part B deductible ($283 in 2026). Plan G premiums vary by state, age, and insurer; across current Plan G policyholders nationally, KFF put the average monthly premium at $164 in 2023, the most recent year for which it publishes that figure.

Head-to-head for the same three utilization scenarios:

The MA-vs-Original-Medicare choice is not really a cost question. It is a risk-tolerance question. Medicare Advantage saves money in low-utilization years and exposes the person to higher cost-sharing in bad years, capped by the MOOP. Original Medicare + Plan G costs more in premium every year and delivers near-total predictability regardless of utilization. For a caregiver deciding on behalf of an aging parent whose health trajectory is uncertain, the predictability of Original Medicare + Plan G is often worth the higher premium.

Extra Help, Low-Income Subsidy, and other financial-assistance programs

Several programs reduce Medicare cost-sharing for people who meet income and resource limits. All 2026 figures below are current-year values:

Extra Help (Low-Income Subsidy for Part D): reduces or eliminates prescription drug premiums, deductibles, and copays. 2026 income limits: $23,940 for an individual, $32,460 for a couple. 2026 resource limits, as published by the Social Security Administration: $18,090 for an individual and $36,100 for a couple — figures that already include the allowance SSA applies when an applicant expects to use some resources for burial expenses. Extra Help applies automatically to full Medicaid recipients and to Supplemental Security Income (SSI) recipients. Others apply through the Social Security Administration.

Medicare Savings Programs (MSPs): reduce or eliminate the Part B premium and some Part A/B cost-sharing. Four tiers with different income thresholds. The Qualified Medicare Beneficiary (QMB) program has the broadest cost-sharing protection; it covers the Part B premium plus Medicare deductibles, coinsurance, and copays. States administer MSPs.

Full Medicaid dual-eligibility: for people who qualify for both Medicare and Medicaid. Medicaid covers cost-sharing that Medicare does not, dental and vision benefits, and long-term services and supports. Dual-eligibles have additional Medicare Advantage plan options through Dual-Eligible Special Needs Plans (D-SNPs) and can change plans more frequently than the standard AEP and MA-OEP windows allow.

For families where the numbers do not work — where the cost estimates in the previous sections exceed what the person can pay — checking eligibility for these programs is the first step. Local State Health Insurance Assistance Programs (SHIPs) provide free counseling on eligibility. When bills have already piled up, help with medical bills covers the assistance programs available for Medicare enrollees.

When it makes sense to work with a patient advocate

The total-annual-cost estimate above is a framework, not a calculation for any specific person. Turning it into a number that actually applies to one loved one requires collecting the loved one’s expected utilization pattern (medications, providers, procedures anticipated), matching that against the specific plans available in the loved one’s ZIP code, and comparing it to Original Medicare + a Medigap policy quoted for the loved one’s age and state.

That comparison is exactly what a patient advocate does. Baba walks through the framework with families, pulls the plan-specific numbers, and produces a total-annual-cost estimate for each realistic option — so the decision is made on numbers rather than averages.

Frequently asked questions

Do I still pay Part B if I have Medicare Advantage?

Yes. Medicare Advantage does not replace Original Medicare — it is a way of receiving Original Medicare benefits through a private plan. The Part B premium ($202.90 per month standard in 2026) is still paid to Medicare regardless of whether the person is in Original Medicare or Medicare Advantage.

Are there any Medicare Advantage plans with truly zero cost?

No. A “$0 premium” Medicare Advantage plan means the plan’s own supplemental premium is $0. The Part B premium is still due. Cost-sharing (deductibles, copays, coinsurance) still applies when services are used. The lowest-cost year for a low utilizer in a $0-premium plan still includes the Part B premium and small copays.

What’s the maximum I could pay out of pocket in 2026?

For in-network services in a Medicare Advantage plan, the 2026 statutory maximum is $9,250. A specific plan may set a lower in-network MOOP — the average across plans in 2026 is $5,421 per KFF data. For PPO plans that cover out-of-network services, the combined MOOP can be up to $13,900. Part D prescription drug cost-sharing has a separate $2,100 out-of-pocket cap in 2026.

Is Medicare Advantage cheaper than Original Medicare?

It depends on utilization and on what “cheaper” means. Medicare Advantage often produces the lowest total annual cost for low utilizers who can access a $0-premium plan with in-network providers and covered medications. Original Medicare paired with a Medigap Plan G often produces more predictable total annual cost for high utilizers, with a higher premium but near-total protection from cost-sharing surprises.

What if I can’t afford my share — is there help?

Yes. Extra Help lowers prescription drug costs for people who meet the 2026 income limits ($23,940 individual, $32,460 couple). Medicare Savings Programs lower Part B premium and Medicare cost-sharing for people who meet state-specific income limits — the Qualified Medicare Beneficiary program has the broadest protection. Full Medicaid dual-eligibility layers on top of Medicare for the lowest-income enrollees. State Health Insurance Assistance Programs offer free counseling on eligibility.
