How Medicare Advantage Out-Of-Pocket Limits Work

You get a cancer diagnosis in January. Suddenly it’s chemotherapy, specialist visits, imaging scans, maybe a hospital stay or two. The bills stack up fast. If you’re on a Medicare Advantage plan, one number could be the difference between financial devastation and a manageable year: your out-of-pocket maximum. That single figure caps how much you’ll ever pay for covered services in a calendar year. Once you hit it, the plan pays 100% for the rest of the year. Most people don’t think about this number until they’re sick. That’s exactly the wrong time to be surprised by it.

What the Medicare Advantage Out-of-Pocket Maximum Actually Is

Medicare Advantage (Part C) is run by private insurance companies approved by Medicare. They have to cover everything Original Medicare covers, but they structure the costs differently. Instead of the open-ended exposure you face with Original Medicare alone, every Medicare Advantage plan must include an out-of-pocket maximum. Let’s call it MOOP.

The MOOP is your annual ceiling on what you personally pay for covered medical services. That means copayments, coinsurance (your percentage of a bill), and deductibles. Hit that number, and the plan covers 100% of in-network covered costs for the rest of the year.

The federal government set the maximum allowable MOOP at $9,350 for in-network services and $14,000 for combined in and out-of-network in 2025. Most plans set their limits lower. A lower MOOP usually signals a more generous plan, though it almost always comes with higher monthly premiums. That tradeoff is worth understanding upfront.

Here’s something people miss: the MOOP only covers services your plan actually covers. Get a service that isn’t covered? Those costs don’t count toward your limit at all. Reading what a plan covers matters as much as knowing the dollar number.

To understand how Medicare Advantage fits into the bigger picture, how Medicare Advantage works walks through the full structure.

How the MOOP Compares to Original Medicare

This one catches people off guard. Original Medicare (Part A and Part B) has no out-of-pocket maximum. Period. If you had a catastrophic health year on Original Medicare alone, your costs could theoretically be infinite. That’s why most Original Medicare enrollees buy a Medigap policy (Medicare Supplement Insurance) to plug the holes.

Medicare Advantage works differently. Instead of layering on a supplement, the Advantage plan itself bakes in the MOOP as built-in protection. For someone expecting significant medical expenses in a given year, that cap can be genuinely lifesaving financially.

But both options have tradeoffs. Comparing Medicare Advantage vs. Original Medicare lays out which structure fits your health situation and budget better.

Medigap plans protect you differently. Plan G, for example, covers most of your cost-sharing after Part B’s deductible, which means your real out-of-pocket exposure is much lower and more predictable. The premiums tend to be higher though. If you’re considering that route, best Medigap plans for 2026 breaks down the most popular choices.

In-Network vs. Out-of-Network: Why the Distinction Matters So Much

This trips up a lot of people. Your plan’s MOOP comes in two versions: one for in-network care, one for combined in and out-of-network. The combined limit is always higher.

See a doctor or hospital in your plan’s network? Those costs count toward your in-network MOOP. Go out of network (if your plan covers it at all), and those costs typically count toward a separate, higher combined maximum.

But here’s what really matters: not all Medicare Advantage plans handle out-of-network care the same. HMO plans generally don’t cover it except in emergencies. PPO plans do allow out-of-network visits, but they cost you more. Knowing which type you have changes how you read your MOOP entirely.

Medicare Advantage HMO vs. PPO spells out the key differences. If you have a PPO and see specialists outside the network regularly, you could spend significantly more before hitting your protection. Always call your doctor’s office to confirm they’re in-network before you go in. Not after.

What Counts Toward the MOOP (and What Doesn’t)

Knowing what actually accumulates toward your maximum matters just as much as knowing the number.

Costs that typically count:

• Copayments for doctor visits, specialists, urgent care, hospital stays
• Coinsurance for hospital care, outpatient procedures, durable medical equipment
• Your plan’s deductible

Costs that typically don’t:

• Monthly premiums (they never count)
• Services your plan doesn’t cover
• Part D prescription drug costs (tracked separately under your drug plan)
• Cost-sharing for out-of-network services if you have a separate out-of-network MOOP

That point about prescription drugs deserves emphasis. Your Part D drug costs follow their own rules. Starting in 2025, the Inflation Reduction Act capped out-of-pocket drug costs at $2,000 per year. That’s huge for people taking expensive medications. But those costs don’t flow into your medical MOOP.

How to Compare Plans Based on the MOOP

When you shop during the Annual Enrollment Period (October 15 to December 7 each year) or a Special Enrollment Period, the MOOP should sit near the top of your list. Here’s how I walk clients through it.

Step 1: Find your plan’s Summary of Benefits. Every Medicare Advantage plan must provide this. It lists your MOOP clearly, along with all cost-sharing details. Check the plan’s website or Medicare.gov.

Step 2: Look at both the in-network and combined MOOP. Write them down. If you ever see specialists or facilities outside your plan’s network, the combined number is what you could hit.

Step 3: Estimate your likely annual costs. How many times do you see a doctor typically? Any procedures or hospitalizations expected? Do you have ongoing conditions requiring regular specialist visits? Generally healthy? A higher MOOP with a lower premium might save you money. High healthcare user? A lower MOOP probably protects you, even with higher premiums.

Step 4: Compare total potential exposure. Multiply your annual premium by 12, then add the MOOP. That’s your worst-case annual cost for each plan. Sometimes a higher-premium plan with a lower MOOP actually costs less in a bad health year.

Step 5: Verify your doctors and hospitals are in-network. Use Medicare.gov’s plan finder or call the plan. Don’t assume anything.

Step 6: Read the Evidence of Coverage. It’s longer and tougher to get through, but if you have a specific condition, it’s worth checking how treatments are covered.

Your MOOP is one of the most important numbers in Medicare Advantage, yet it’s invisible until something goes wrong. Spending an hour comparing MOOPs across plans during open enrollment could save you thousands in unexpected costs. You don’t have to figure this out alone. A free call with a SHIP counselor, Medicare.gov’s plan finder, and your Summary of Benefits put you way ahead of most people.
