TL;DR — Quick Verdict
- In 2026, CMS caps Medicare Advantage in-network out-of-pocket maximums at $9,350 and combined in/out-of-network maximums at $14,000 — but many plans set their limits lower.
- The MOOP only applies to Part A and Part B services; Part D drug costs, dental, vision, and hearing are excluded from the cap calculation.
- Plans from carriers like Humana and UnitedHealthcare vary widely — some benchmark plans carry MOOPs as low as $3,000–$4,000 in competitive urban markets.
- Once you hit your MOOP, the plan pays 100% of covered in-network costs for the rest of the calendar year — but the clock resets every January 1.
- Beneficiaries with chronic conditions or anticipated surgery should prioritize MOOP over premium when selecting a plan during Annual Enrollment (October 15 – December 7).
- Bottom line: A plan with a $0 premium and a $9,350 MOOP can cost you $9,350 more than a $60/month premium plan with a $3,500 MOOP if you have a major health event — do the math before you enroll.
The average Medicare beneficiary enrolled in a Medicare Advantage plan has no idea what their out-of-pocket maximum actually is — until they get a serious diagnosis. According to the Kaiser Family Foundation (KFF), the average Medicare Advantage enrollee faces a maximum out-of-pocket limit of roughly $4,972 for in-network services in 2024, well below the federal ceiling, yet still capable of devastating a fixed-income household. In 2026, CMS set the statutory ceiling at $9,350 for in-network costs and $14,000 for combined in- and out-of-network exposure. Those aren’t targets — they’re ceilings. What your specific Humana, Aetna, UnitedHealthcare, or BCBS plan actually caps your liability at is a different number, printed on page one of your Summary of Benefits. This article breaks down exactly how the Medicare Advantage out-of-pocket maximum (MOOP) works, what it counts, what it excludes, how to compare plans on this single metric, and when a higher-premium plan with a lower MOOP is mathematically the smarter buy.
What the Medicare Advantage Out-of-Pocket Maximum Actually Is — and Isn’t
The MOOP is a hard annual ceiling on what you pay out-of-pocket for Medicare Part A and Part B-covered services within your plan’s network. Once your cost-sharing — copays, coinsurance, and deductibles for covered services — hits that ceiling, your plan absorbs 100% of covered costs for the remainder of the calendar year. CMS mandates that every Medicare Advantage plan include a MOOP; no plan can legally omit it.
But the definition of “what counts” toward the MOOP is where most beneficiaries get burned. The following costs accumulate toward your MOOP: hospital stays (Part A), outpatient services (Part B), specialist visits, lab work, imaging, durable medical equipment, and chemotherapy. These costs do not count: Part D prescription drug cost-sharing, standalone dental premiums or claims, vision hardware, hearing aids, and any out-of-network costs if your plan has an in-network-only MOOP structure.
Plans may offer two separate MOOPs — one for in-network services only, and a combined in/out-of-network limit. CMS caps the in-network limit at $9,350 and the combined limit at $14,000 for 2026. If your plan has a $9,350 in-network MOOP and you use an out-of-network provider, costs incurred out-of-network may count only toward the higher combined cap — or not at all, depending on your plan type. HMO plans typically provide no out-of-network coverage (emergencies excepted); PPO plans typically apply a separate, higher out-of-network cost share.
One critical reset mechanism: the MOOP resets every January 1, regardless of where you were in the calendar year. A beneficiary who hits their MOOP on November 30 resets to zero on January 1. If you have a surgery scheduled in November, this timing can determine thousands of dollars in personal liability.
2026 MOOP Limits by Plan Type: What Real Plans Actually Charge
The federal ceiling tells you the worst-case scenario, not the typical scenario. Plan-level MOOPs vary dramatically by carrier, plan tier, and county. KFF’s annual Medicare Advantage enrollment and plan data — drawn from CMS’s publicly released landscape files — shows meaningful spread between what’s legally allowed and what’s actually offered. The table below reflects the 2026 CMS statutory limits alongside published benchmark ranges from major carriers where plan data has been released.
Sources: CMS 2026 Medicare Advantage and Part D Rate Announcement (verify at cms.gov); KFF Medicare Advantage 2024 Spotlight: First Look (verify at kff.org). Carrier-tier ranges are illustrative of published plan distributions; verify your specific plan’s MOOP in its 2026 Summary of Benefits.
The pattern is consistent: lower premiums correlate with higher MOOPs. Carriers structure plans this way deliberately — the $0-premium plan transfers catastrophic cost risk to the enrollee. A beneficiary who selects a $0-premium HMO with a $9,350 MOOP and then requires a joint replacement (average Medicare cost: $15,000–$30,000 per CMS bundled payment data) will hit their MOOP and pay $9,350. The same beneficiary on a $120/month premium plan with a $3,500 MOOP pays $1,440 in annual premiums plus $3,500 — a total of $4,940, saving over $4,400 in a major-event year.
$0-Premium Plan vs. Higher-Premium Plan: Which Is Better When You Get Sick?
This is the comparison most brokers avoid having on paper. Let’s model it with two real-world plan archetypes for a 68-year-old beneficiary in a medium-cost metro market who has a hip replacement in March — a common, high-cost, planned procedure.
Scenario modeled by Real Cost Report editorial team using CMS cost-sharing parameters and KFF plan distribution data (verify at kff.org). Copay estimates based on typical MA plan structures; verify against your plan’s Evidence of Coverage.
In a healthy year — four primary care visits, no hospitalizations — Plan A wins by over $1,400. In a major-event year, Plan B saves $3,280. The break-even point comes when your annual claims cost-sharing on Plan A exceeds your premium differential on Plan B by the MOOP difference. For most beneficiaries over 70, or anyone with a chronic condition requiring regular specialist care, the math increasingly favors the higher-premium, lower-MOOP structure.
Verdict
Beneficiaries who are generally healthy and rarely exceed a few hundred dollars in annual medical costs should consider a $0-premium plan only if its MOOP is below $6,000. Anyone with a scheduled procedure, a chronic condition like CHF or COPD, or a history of hospitalization should calculate total maximum exposure — premium + MOOP — before selecting a plan. In most cases, a mid-tier PPO with a MOOP under $5,000 delivers better financial protection for the population most likely to use it.
What Most People Get Wrong About the Medicare Advantage MOOP
Misunderstanding the MOOP costs beneficiaries real money. Here are the five most consequential mistakes, what they lead to, and the correct action in each case.
Mistake 1: Assuming the MOOP covers prescriptions. Many enrollees hit a surprise drug cost in Q4 and assume it’s moving them toward their MOOP ceiling. It isn’t. Part D drug cost-sharing — even within a plan that bundles medical and drug coverage — does not accumulate toward the Part A/B MOOP. Consequence: Beneficiaries budget incorrectly and get blindsided by simultaneous medical and drug cost exposure. Correct action: Track your drug costs separately under the Part D out-of-pocket cap structure, which changed significantly under the Inflation Reduction Act — drug OOP costs are now capped at $2,000 in 2025 and indexed thereafter (verify at cms.gov).
Mistake 2: Treating the federal ceiling as the plan’s actual limit. Seeing “$9,350 MOOP” in a CMS headline and assuming that’s what your plan charges is a dangerous shortcut. Some plans have MOOPs well below the ceiling. Correct action: Pull the Summary of Benefits for every plan you’re comparing — it’s a standardized document CMS requires all MA plans to publish, and the MOOP appears on the first page.
Mistake 3: Ignoring the in-network vs. combined distinction on PPO plans. A PPO with a $4,500 in-network MOOP and a $12,000 combined MOOP may offer very little real protection if you see providers outside the network. Out-of-network cost-sharing is typically 50% on PPO plans, meaning your out-of-network costs accumulate only toward the much higher combined cap. Consequence: A beneficiary who sees a non-participating specialist after a hospitalization can face massive cost exposure they didn’t model. Correct action: For PPOs, calculate your risk using the combined MOOP if you have any likelihood of going out of network.
Mistake 4: Forgetting that the MOOP resets January 1. Timing elective procedures near year-end without accounting for the reset can double your exposure. A beneficiary who hits their MOOP in November and has a follow-up surgery in January starts again at zero. Correct action: If you hit your MOOP by September, schedule any elective or non-urgent procedures before December 31.
Mistake 5: Evaluating the MOOP without accounting for chronic disease progression. A 64-year-old selecting a plan with a high MOOP may be making a sound actuarial bet. The same person at 71 with newly diagnosed Type 2 diabetes and early-stage CKD is in a materially different risk profile. Correct action: Re-evaluate your plan’s MOOP during every Annual Enrollment Period against your current health status, not the status you had when you first enrolled.
Who Should Prioritize a Low MOOP — and Is It Worth the Higher Premium?
Not every Medicare Advantage enrollee needs to obsess over the MOOP. But for certain profiles, it’s the single most important line item in the plan comparison. Use the following conditional framework to assess your situation.
Prioritize the lowest available MOOP if: You have a diagnosed chronic condition (heart disease, diabetes, COPD, CKD, cancer history) that results in regular specialist visits or hospitalizations. You are scheduled for a procedure within the next 12 months. You are over 75, when hospitalization rates rise sharply — the CDC’s National Center for Health Statistics reports hospitalization rates for adults 75+ are approximately three times the rate for adults 45–64. You have limited liquid savings; even a $5,000 MOOP can be financially catastrophic on a $28,000/year Social Security income.
The higher-premium, lower-MOOP plan is worth it when: The premium differential multiplied by 12 is less than the MOOP differential. Example: Plan A has a $9,000 MOOP and $0 premium. Plan B has a $4,500 MOOP and $125/month premium. Premium cost: $1,500/year. MOOP savings in a bad year: $4,500. Break-even: the plan pays for itself if you incur more than $1,500 in cost-sharing — easily cleared with a single hospitalization or major outpatient procedure.
The $0-premium, higher-MOOP plan may be appropriate if: You are under 68, have no chronic conditions, are not on specialty medications, and have $10,000+ in accessible liquid savings that could absorb the MOOP in a worst-case scenario. Even then, revisit this calculation every year during Annual Enrollment.
Dual-eligible beneficiaries — those who qualify for both Medicare and Medicaid — should note that D-SNP plans (Dual Eligible Special Needs Plans) typically carry $0 or near-$0 MOOPs, and Medicaid serves as secondary coverage. If you think you may qualify for Medicaid’s spend-down program based on high medical costs relative to income, contact your State Health Insurance Assistance Program (SHIP) counselor at no cost. SHIP counselors are federally funded and prohibited from selling insurance.
What’s Changed in 2026: MOOP Limits and Plan Landscape Shifts
CMS’s 2026 Medicare Advantage and Part D Rate Announcement, released in April 2025, confirmed the statutory MOOP ceiling at $9,350 for in-network and $14,000 for combined costs — unchanged from 2025 in nominal terms. However, several structural shifts affect how those ceilings translate to real enrollee exposure.
First, plan consolidation continued in 2025–2026. Several major carriers reduced plan offerings in lower-density markets, reducing competitive pressure on MOOPs in rural counties. Beneficiaries in non-metro areas may find fewer low-MOOP options than in prior years. CMS’s plan landscape data (verify at cms.gov) shows the average number of plans available per county declined in approximately 30% of rural markets.
Second, the Inflation Reduction Act’s $2,000 Part D out-of-pocket cap — fully effective in 2025 — has reduced one major source of financial exposure, but it has also prompted some carriers to restructure their formularies and cost-sharing tiers. Beneficiaries on specialty drugs should re-verify their drug tier placement in 2026, as tier changes can materially affect total annual cost even if the MOOP is unchanged.
Third, CMS introduced enhanced oversight of marketing practices in 2025, making it marginally harder for brokers to steer beneficiaries toward high-MOOP plans for commission reasons. However, independent verification of your plan’s MOOP in the official Summary of Benefits remains the only fully reliable check.
