Your maximum out-of-pocket limit, or MOOP, is the annual cap on what you pay in covered medical cost-sharing. The critical Medicare fact: Original Medicare has no MOOP. Medicare Advantage plans are required to set one. Part D prescription drug costs generally do not count toward a Medicare Advantage MOOP.
Three things to do right now:
- Pull out your Evidence of Coverage and find your plan’s MOOP number.
- Confirm whether your MOOP applies to in-network care only, or to out-of-network care as well.
- Note whether your plan has a separate in-network MOOP and a higher combined MOOP.
Key Takeaways
The single most important fact: Original Medicare has no MOOP, so Medicare Advantage plans are the primary tool for capping your annual covered medical cost-sharing.
| Point | Details |
|---|---|
| MOOP definition | The annual cap on covered cost-sharing; after you reach it, the plan pays 100% of covered in-network services. |
| Original Medicare has no MOOP | Without a supplement or Advantage plan, your Part A/B cost-sharing has no annual ceiling. |
| 2026 Marketplace caps | Individual cap is $10,600 for 2026, per Healthcare.gov. |
| Part D usually excluded | Drug costs in most Medicare Advantage plans do not count toward the medical MOOP. |

How MOOP works across Medicare plan types
The structure of MOOP protection depends entirely on which type of Medicare coverage you have. Here is how each plan type handles it.
Original Medicare (Parts A and B) covers hospital and medical services but sets no annual cap on your cost-sharing. There is no ceiling. That exposure is one reason many beneficiaries add a Medigap supplement or switch to Medicare Advantage.
Medicare Advantage (Part C) plans are required by CMS regulations to set an annual MOOP. Every plan must have one, and many plans set their MOOP below the regulatory maximum. Once you reach it, covered in-network services cost you nothing for the remainder of the benefit year.
Medicare Part D covers prescription drugs. In most Medicare Advantage plans, Part D cost-sharing does not count toward the plan’s medical MOOP. The two buckets stay separate. Some standalone Part D plans have their own out-of-pocket protections, but those are distinct from the MA MOOP.
In-network vs. out-of-network: PPO-style Medicare Advantage plans often carry two MOOP figures. One applies to in-network care. The second, higher figure applies to combined in-network and out-of-network spending. HMO plans typically have only an in-network MOOP because they generally do not cover out-of-network care at all. You can verify which structure your plan uses in the Summary of Benefits, which every plan must provide.
| Plan Type | Has a MOOP? | Notes |
|---|---|---|
| Original Medicare (A/B) | No | Unlimited cost-sharing exposure |
| Medicare Advantage (Part C) | Yes, required | May have separate in-network and combined limits |
| Medicare Part D | Separate protections | Drug costs usually excluded from MA MOOP |
| Marketplace (ACA) plans | Yes, statutory cap | Different caps from MA; see 2025/2026 figures below |
Pro Tip: Always read the Summary of Benefits first. It lists both the in-network and combined MOOP on one page, usually near the top. The Evidence of Coverage gives the full legal detail if you need to dig deeper.
What counts toward your MOOP and what does not
Knowing which payments accumulate toward your MOOP is just as important as knowing the number itself.
Costs that typically count:
- Your deductible for covered Part A and Part B services from in-network providers
- Copayments for covered in-network visits and procedures
- Coinsurance for covered in-network services (for example, 20% of a specialist bill)
Costs that do not count:
- Monthly premiums. Paying your premium every month does not move you one dollar closer to your MOOP.
- Services the plan does not cover. If your plan excludes a specific treatment, what you pay for it is invisible to the MOOP counter.
- Most out-of-network charges, unless your plan explicitly states otherwise. Going outside the network on an HMO plan often means you pay the full bill, and none of it counts.
- Charges above the plan’s allowed amount. If a provider bills more than what the plan allows, the excess is your responsibility and does not count toward MOOP.
- Part D drug costs in most Medicare Advantage plans. Prescription spending runs on a separate track.
Supplemental benefits such as vision, hearing, and dental are a gray area. Some Medicare Advantage plans include cost-sharing for these benefits in the MOOP calculation. Others exclude them entirely. Medicare Interactive confirms that this varies by plan and must be verified in the Evidence of Coverage.
Pro Tip: Search your Evidence of Coverage for the phrase “maximum out-of-pocket” and read every sentence around it. Plans are required to list exactly which services count. If the language is vague, call the plan directly and ask them to confirm in writing.
Understanding Medicare copays and deductibles helps you track which payments are accumulating toward your limit and which are not.
MOOP limits by plan type for 2026
Plan-level MOOPs vary, but federal rules set a ceiling that no plan can exceed. Here are the current figures.
Medicare Advantage (2026): The 2026 regulatory cap for Medicare Advantage in-network MOOP is set by CMS, and individual plans may set their MOOP lower than this cap, with variability across plans. The lower the plan’s MOOP, the more protection you have, though that often comes with a higher monthly premium or a narrower provider network.
Marketplace (ACA) plans: Healthcare lists the statutory caps for Marketplace plans. For the 2025 and 2026 plan years, the Marketplace individual and family out-of-pocket caps vary and are set by statutory limits. These caps apply to Marketplace plans and not to Medicare Advantage.
Key figure: The 2026 Marketplace individual MOOP cap is $10,600, up from $9,200 in 2025. Medicare Advantage plans operate under a separate regulatory cap set by CMS.
Policy year vs. calendar year: Most Medicare Advantage plans run on a calendar year, so your MOOP resets on January 1. Marketplace plans also follow a calendar year. Confirm the benefit year start date in your plan documents, especially if you enrolled mid-year.
Where to find your plan’s actual MOOP: The Summary of Benefits lists it prominently. The Evidence of Coverage provides the full legal definition of what counts. Medicare offers a plan finder tool where you can compare MOOP figures across available plans in your area.

What actually happens when you hit your MOOP
Two case walkthroughs make this concrete.
Case A: High-use beneficiary who reaches MOOP mid-year
Margaret, 72, has a Medicare Advantage HMO with a $4,500 in-network MOOP and a $300 annual deductible. In January she has a hospital stay. Here is how her costs accumulate:
- She pays her $300 deductible first. Running total: $300.
- Her plan charges 20% coinsurance on the hospital stay. Her share comes to $1,800. Running total: $2,100.
- In March she has outpatient surgery. Her coinsurance share is $1,400. Running total: $3,500.
- By June, specialist copays and a follow-up procedure add another $1,000. Running total: $4,500.
Margaret has reached her MOOP. From July through December, every covered in-network service costs her nothing in cost-sharing. She still pays her monthly premium, and any non-covered services remain her responsibility.
Case B: Low-use beneficiary who never approaches MOOP
David, 68, is generally healthy. He sees his primary care doctor twice and fills a few prescriptions. His total in-network cost-sharing for the year is $420. His plan’s MOOP is $3,200. He never comes close. For David, the MOOP is a safety net he did not need this year, but it caps his worst-case exposure if something unexpected happens.
PPO dual-MOOP note: If Margaret had a PPO with a $4,500 in-network MOOP and a $7,500 combined MOOP, seeing an out-of-network specialist would add costs to the combined counter but not the in-network one. She could hit the in-network MOOP and still owe money for out-of-network care until she reached $7,500 total. That distinction catches many beneficiaries off guard.
For strategies on reducing Medicare out-of-pocket costs before you reach your MOOP, Paulbinsurance outlines practical steps worth reviewing.
How to use MOOP when choosing a Medicare plan
MOOP is one of the most useful numbers for comparing plans, but only when you read it alongside premiums, network size, and your expected care needs.
Step-by-step decision framework:
- Estimate your expected annual care. Think about last year. How many specialist visits, procedures, or hospital stays did you have? Use that as a baseline.
- Calculate your worst-case cost under each plan. Add the annual premium to the plan’s MOOP. That is the most you would pay in a bad year. A plan with a $0 premium and a $7,500 MOOP costs you up to $7,500. A plan with a $120/month premium and a $3,000 MOOP costs you up to $4,440. The second plan wins in a bad year.
- Evaluate the provider network. A low MOOP means little if your doctors are not in-network. Out-of-network costs may not count toward your MOOP at all.
- Check how Part D fits. If you take multiple medications, confirm whether the plan bundles Part D coverage and whether drug costs count toward the MOOP. They usually do not, but verify.
Questions to ask an agent or plan representative:
- Does this MOOP apply to in-network care only, or does it include out-of-network spending?
- Do Part D drug costs count toward this MOOP?
- Are supplemental benefits like vision and dental included in the MOOP calculation?
- What is the combined MOOP if I use out-of-network providers?
Red flags to watch for:
- A very low MOOP paired with an extremely narrow network. You may save on paper but struggle to find covered providers.
- Vague Evidence of Coverage language about which services count toward MOOP. If the document does not list it clearly, ask for written clarification.
- A plan that does not clearly separate in-network and combined MOOP figures. That ambiguity can cost you.
The Healthline overview of Medicare out-of-pocket maximums provides useful comparative context on how beneficiary cost burdens differ across plan types, which helps frame these trade-offs.
For a side-by-side look at Medicare Advantage vs. supplement plans, Paulbinsurance walks through the key decision points in plain language.
What Paul Barrett sees after years of helping Medicare clients
Paul Barrett has been helping Medicare consumers since 2007. Three mistakes come up repeatedly when beneficiaries evaluate MOOP.
Common mistakes:
- Assuming Part D counts toward the MOOP. Most Medicare Advantage plans keep drug cost-sharing in a separate bucket. Beneficiaries who take expensive medications sometimes choose a plan based on a low MOOP, then discover their drug costs are not moving that number at all.
- Assuming out-of-network care counts. On HMO plans, it almost never does. On PPOs, it may count toward a combined MOOP but not the in-network one. Either way, going out of network without understanding the rules can produce bills that feel like they should count but do not.
- Ignoring supplemental benefit limits. A plan may offer dental coverage, but if dental cost-sharing does not count toward the MOOP, a major dental procedure leaves you exposed in a way the MOOP number never suggested.
Localization note: Plan offerings vary by county and state. A plan available in one ZIP code may not exist in the next. Always confirm plan availability and MOOP figures for your specific area using Medicare.gov’s plan finder or by speaking with a licensed agent who knows your local market. State-specific rules can also affect how supplemental benefits are structured.
Pro Tip: When you receive your annual Notice of Change each fall, compare the new MOOP to the prior year’s figure before you do anything else. Plans can raise or lower their MOOP at renewal, and that single number can change your worst-case exposure by thousands of dollars.
Why MOOP matters more than most people realize
Most people do not think about their MOOP until they are already in a medical crisis. By then, the bills are arriving and the plan comparison window has closed.
Consider what it means for an older adult facing a serious diagnosis in February. Without a MOOP, every covered service carries ongoing cost-sharing with no end in sight. With a well-chosen Medicare Advantage plan, the financial exposure stops at a known number, often before summer. That predictability is not just financial relief. It is the difference between focusing on recovery and spending every week calculating what the next appointment will cost.
The practical actions are straightforward: find your MOOP number today, estimate your likely care for the year, and if you are not sure whether your current plan is the right fit, talk to an agent before the next enrollment window closes. Lowering your out-of-pocket Medicare costs starts with knowing exactly what your plan’s ceiling is.
