Learn about the importance of Medicare out-of-pocket costs and out-of-pocket maximums in this comprehensive guide.

When determining the cost of a Medicare plan, it’s important to look beyond the premiums to see what your total healthcare costs might be. Of course, it’s impossible to confirm all of the services you’ll need in a year, but understanding how your out-of-pocket costs work can help you avoid surprises when your medical bills are due.
Your out-of-pocket costs include everything you pay for healthcare services aside from your premiums—in other words, your deductibles, copayments, and coinsurance. A deductible is the amount you have to spend before your insurance begins to cover its portion of your healthcare. Copayments are a set amount you pay for specific services. Your coinsurance is the percentage of costs you’ll cover once you meet your deductible.
Your out-of-pocket costs are important for two key reasons. First, by understanding your deductible, copays, and coinsurance amounts, you can better estimate the cost of services before you receive treatment. Second, supplemental Medicare plans come with out-of-pocket maximums that protect you from catastrophic costs. You'll need to understand how each treats out-of-pocket costs to choose the best combination of Medicare parts and plans for your needs.
If you need help paying for out-of-pocket costs associated with Medicare coverage, you can sign up for Medicare Savings Programs if you meet the eligibility criteria.
Lastly, make sure you know when to enroll in Medicare to avoid late enrollment penalties for Medicare premiums. This will ensure that you minimize any additional charges on your healthcare.
Original Medicare is made up of Part A (inpatient insurance) and Part B (outpatient insurance). Each part has its own out-of-pocket costs.
Medicare Part A covers hospital stays, skilled nursing facility stays, home health care, and hospice care. Medicare helps cover the first 60 days of a hospital stay for each benefit period. For the first 60 days of a stay at a hospital, you’ll pay nothing after you reach the Part A deductible ($1,676 in 2025). For days 60-90, you’ll have to pay a daily copay of ($419 in 2025). If you reach 90 days and you’re out of lifetime reserve days, you’ll have to pay all hospital costs out of pocket.
For a stay at a skilled nursing facility, you’ll pay $0 for days 1-20. For days 21-100, you’ll pay a daily copay ($209.50 in 2025). And for day 101 and beyond, you’ll be responsible for all costs.
If you have Medicare Supplement insurance, your plan will pay the Part A deductible. It will also cover up to 365 days of additional hospital coverage.
Medicare Part B covers your medical insurance, including doctor visits, outpatient procedures, and durable medical equipment. After you meet your Part B deductible, Medicare covers 80% of covered services. You’re responsible for paying the remaining 20% (this is your coinsurance). Because Original Medicare has no out-of-pocket limit, you could be on the hook for thousands of dollars if you have more considerable medical expenses.
For this reason, most people on Medicare choose to enroll in either a Medicare Supplement or Medicare Advantage plan to limit their out-of-pocket costs.
Medigap (also called Medicare Supplement) plans were designed to limit out-of-pocket expenses by filling the gaps in costs not covered by Original Medicare. There are ten different types of Medigap plans with different coverage options. Regardless of the plan you choose, you can significantly limit your out-of-pocket expenses and have greater financial predictability.
Most plan types eliminate coinsurance. The two that don’t eliminate coinsurance (Medigap Plan K and Medigap Plan L) still significantly reduce your coinsurance and come with out-of-pocket limits. Use the chart found here to understand how out-of-pocket costs work for each type of Medigap plan. And remember, each type of plan (so, all Medigap Plan Ms) will have the exact same coverage even if they have different insurance carriers or premiums.
Plan G and Plan N are two popular plans that reduce your out-of-pocket costs the most. Both plans cover everything except the Part B deductible. The difference between them is that Plan N doesn’t cover Part B excess charges.
Medicare Part D is your prescription drug coverage. Part D is generally included in Medicare Advantage plans. If you’re on a Medigap plan or a Medicare Advantage plan that does not have prescription coverage, you can enroll in a separate Part D plan. Part D plans, like other insurance plans, have deductibles, copayments, and coinsurances—but how these costs work is more complex.
The various drug plans cover different prescriptions. Plans also place drugs on different tiers, and higher-tier drugs will have higher costs. To understand a plan's drug coverage, you can check its formulary (drug list) and identify the tiers your drugs fall within. All Part D plans also have four phases during which you'll pay different amounts for the same drugs.
During your deductible phase, you’ll pay 100% of the cost of drugs. Your deductible will vary depending on your specific Part D plan, but no plan may have a deductible higher than $590 (in 2025). It's worth noting that the average Part D deductible went up from $423 in 2024 to $486 in 2025.
Some Part D plans don’t have a deductible. Others that do have a deductible will cover some drugs before you’ve met your deductible. Pay attention to which drugs are on your plan and how they’re covered to maximize your savings.
You and your drug plan share your costs during your drug coverage's initial phase. You'll owe 25% of the cost of generic and brand name drugs covered by your plan. Your 25% share of costs is your coinsurance. The Initial Coverage Phase lasts until your out-of-pocket costs for prescriptions reaches $2,000 for the year. From here, you enter the Catastrophic Phase.
*Note: The Part D Coverage Gap Phase has been eliminated
Once your total out-of-pocket costs have hit $2,000 (in 2025), you’ll enter the catastrophic phase. During this phase, you'll pay nothing for your covered drugs for the rest of the year.
Finding a prescription drug plan that saves you money on the prescriptions you need is one of the things Chapter Medicare Advisors do best! We’re careful to check each and every medication you take to be sure you’re on a plan that provides the best coverage. If you’re having trouble paying, we’ll help to determine if you can save money by changing your pharmacy or enrolling in the Part D Extra Help Program (a low–income subsidy).
The Inflation Reduction Act of 2022 has lowered the cost burden of prescriptions. This regulation lowered the cost of common prescription drugs, capped out-of-pocket spending, and eliminated copays or coinsurance for CDC-recommended vaccines.
Medicare Advantage plans are an alternative to Original Medicare. They cover at least the same amount as Parts A and B and often have extra coverage for things like dental and vision care and prescriptions. Since private insurance companies manage these plans, they vary widely with their out-of-pocket costs. These differences matter when looking at covered drugs, additional benefits, premiums, deductibles, and copayments.
While out-of-pocket costs will vary for Medicare Advantage plans, they must all have an out-of-pocket yearly limit of no more than $9,350 for covered, in-network medical services (in 2025). Some plans may choose to have a lower out-of-pocket limit. Once you hit your limit, your plan will pay 100% of the costs for covered medical services.
Medicare Advantage plans also have network providers and prior authorization requirements. If you go out of network, your out-of-pocket costs will likely increase. Similarly, if you are denied prior authorization, you may have to pay medical services yourself.
