What if a single hospital bill could wipe out your savings?
That’s why the out-of-pocket maximum exists: it’s the most you’ll pay in a plan year for covered, in-network care, and once you hit it your plan pays 100% of covered costs.
Think of it as a year-long cap that keeps major medical bills from becoming long-term debt.
This post shows what counts toward that limit, what doesn’t, and how to use the number to pick a plan that balances protection and monthly cost.
Core Explanation of the Out-of-Pocket Maximum
An out-of-pocket maximum is the most you’ll pay in a plan year for covered, in-network medical services. Once you hit this limit, your health insurance picks up 100% of all covered costs for the rest of that plan year. This cap exists to protect you from unlimited medical bills, even when you’re facing serious illness, surgery, or ongoing treatment.
The out-of-pocket maximum only applies to covered services. Non-covered treatments, balance-billed charges, and monthly premiums don’t count toward this limit. If your plan states an individual out-of-pocket maximum of $5,000, you won’t pay more than $5,000 in cost sharing for covered, in-network care in that year, no matter how high your medical bills climb.
After you reach your out-of-pocket maximum:
Your insurer covers 100% of all covered, in-network services for the rest of the plan year. You keep paying monthly premiums but owe no copays, coinsurance, or deductibles for covered care. The protection kicks in the moment you hit the cap and lasts until your plan year resets. New expenses reset to zero at the start of your next plan year.
Out-of-pocket maximums reset annually on your plan year start date, which is often January 1 for many employer and marketplace plans but can vary. Some plans have separate out-of-pocket maximums for individual coverage and family coverage. If your plan has a family out-of-pocket maximum of $10,000, your household’s combined eligible expenses stop accruing once that family cap is reached, even if no single family member has individually hit the lower individual cap.
Costs That Count Toward the Out-of-Pocket Maximum
Deductible payments are the first dollars you pay for covered services, and they count directly toward your out-of-pocket maximum. If your plan has a $2,000 deductible and you pay that full amount during the year, those $2,000 in payments move you closer to your maximum. The deductible is often the largest single piece of your cost sharing, especially early in the plan year.
Copayments for covered, in-network services typically count toward the out-of-pocket maximum. Every time you pay a $30 copay for a primary care visit or a $50 copay for a specialist, that amount gets tracked and added to your running total. Most health plans apply copays to the out-of-pocket limit, though you should confirm in your plan documents because a small number of plans handle copays differently.
Coinsurance also counts toward your out-of-pocket maximum. Coinsurance is the percentage of a bill you pay after meeting your deductible. A plan with 20% coinsurance means you pay 20% of the allowed amount and your insurer pays 80%. If a hospital stay costs $10,000 and you’ve met your deductible, you pay $2,000 (20%) and that $2,000 goes toward your out-of-pocket maximum. Once your combined deductible, copays, and coinsurance reach the cap, you stop paying coinsurance for the rest of the year.
Most covered, in-network expenses count toward the maximum. Deductible amounts paid for covered medical services. Copays for doctor visits, specialist appointments, urgent care, and emergency room visits. Coinsurance percentages paid after the deductible is met. Covered prescription drug cost sharing like copays or coinsurance for medications, if the plan includes drug coverage under the same out-of-pocket maximum. Cost sharing for covered diagnostic tests, lab work, imaging, surgery, hospital stays, and other in-network medical services.
Costs That Do Not Count Toward the Out-of-Pocket Maximum
Monthly premiums never count toward your out-of-pocket maximum. You pay premiums to keep your insurance active, regardless of whether you use any medical services. Even after you reach your out-of-pocket maximum and your insurer covers 100% of covered care, you still owe your monthly premium. If you pay $400 per month in premiums and hit your $6,000 out-of-pocket maximum in June, you’ll continue paying $400 every month for the rest of the year.
Balance-billed charges from out-of-network providers generally don’t count toward the out-of-pocket maximum for in-network coverage. Balance billing happens when an out-of-network provider charges more than your plan’s allowed amount and bills you for the difference. Those extra charges often fall outside the protection of the out-of-pocket maximum. Some plans have separate, higher out-of-pocket maximums for out-of-network care, but many exclude out-of-network costs entirely.
Common exclusions that don’t count toward the out-of-pocket maximum include monthly insurance premiums, services not covered by your plan (cosmetic procedures, experimental treatments, non-approved medications), balance-billed amounts when you use an out-of-network provider and the provider charges above the plan’s allowed rate, and out-of-network cost sharing unless your plan explicitly includes out-of-network services in the same out-of-pocket maximum or has a separate out-of-network cap.
How Out-of-Pocket Maximums Protect Consumers
Out-of-pocket maximums cap your financial exposure in a plan year, preventing a single illness or accident from causing unlimited medical debt. Before the Affordable Care Act established annual limits, some plans had no out-of-pocket maximum or set caps so high that families faced bankruptcy from a serious diagnosis. The ACA now requires all compliant health plans to include an annual out-of-pocket maximum, with federal caps adjusted each year.
For 2024, federal ACA compliant marketplace plans have out-of-pocket maximums capped at $9,450 for individual coverage and $18,900 for family coverage. Employer plans and other types of coverage may have lower maximums. These limits make sure that even if you undergo chemotherapy, major surgery, or extended hospital care, your total cost sharing for covered, in-network services won’t exceed the plan’s stated maximum.
Out-of-pocket maximums are especially protective during high expense years. If you have a planned surgery, a baby, or a chronic condition requiring frequent specialist visits and expensive medications, you can calculate your worst case annual spending by adding up monthly premiums and the out-of-pocket maximum. That clarity helps you budget and choose a plan with a manageable maximum, even if the monthly premium is slightly higher. A lower out-of-pocket maximum reduces your financial risk when you know you’ll use significant medical care.
Realistic Examples of How an Out-of-Pocket Maximum Works
Out-of-pocket maximums limit your total cost sharing across the entire plan year. Here are two common scenarios showing how the cap works in practice.
Example 1, single major event: You have a plan with a $1,500 deductible, 20% coinsurance, and a $5,000 out-of-pocket maximum. In March, you have surgery with a total allowed cost of $25,000. You pay the $1,500 deductible, then 20% of the remaining $23,500, which is $4,700. But your out-of-pocket maximum is $5,000, so your actual payment stops at $5,000 total ($1,500 deductible plus $3,500 in coinsurance). Your insurer covers the remaining $20,000 of the surgery bill and pays 100% of all covered, in-network care for the rest of that plan year.
Example 2, multiple ongoing expenses: You have the same plan. Over the year, you pay $1,500 toward the deductible through regular doctor visits and tests. Then you have physical therapy sessions with $40 copays and prescription drug copays adding up to $1,200. You also have a small outpatient procedure with $2,300 in coinsurance. Your total cost sharing is now $5,000. From that point forward, any covered, in-network care (more therapy, follow-up visits, additional prescriptions) costs you nothing because you’ve reached your out-of-pocket maximum.
| Scenario | Total Covered Costs | Amount You Pay | Insurer Pays |
|---|---|---|---|
| Surgery in March (Example 1) | $25,000 | $5,000 (capped at OOP max) | $20,000 |
| Year-long care (Example 2) | $12,000 | $5,000 (deductible + copays + coinsurance until OOP max) | $7,000 plus 100% after max |
| Catastrophic year (cumulative $80,000) | $80,000 | $5,000 (capped) | $75,000 |
Out-of-Pocket Maximum vs. Deductible
The deductible is the amount you must pay for covered services before your insurance begins sharing costs through coinsurance or full coverage. It’s usually the first threshold you cross each plan year. Once you meet the deductible, your plan starts paying a percentage of bills, and you pay the remaining percentage (coinsurance) or a fixed copay, depending on the service.
The out-of-pocket maximum is the total cap on your cost sharing for the entire plan year. It includes the deductible, plus all copays and coinsurance you pay after the deductible is met. Once you reach the out-of-pocket maximum, the insurer pays 100% of covered, in-network costs for the rest of the year.
Here’s how they’re different. Deductible is a starting threshold. Out-of-pocket maximum is the ceiling on your total spending for cost sharing. Deductible applies before most coverage begins. Out-of-pocket maximum applies after you’ve paid the deductible plus additional copays and coinsurance. Reaching the deductible triggers cost sharing (you start splitting bills with the insurer). Reaching the out-of-pocket maximum ends cost sharing (insurer pays 100%). A plan might have a $2,000 deductible and a $6,000 out-of-pocket maximum, meaning you pay up to $2,000 first, then continue paying copays and coinsurance until your total reaches $6,000.
These two limits work together to structure your annual costs. In a plan with a $1,000 deductible and a $4,000 out-of-pocket maximum, you’ll pay the first $1,000 of covered costs in full. After that, you pay copays or coinsurance until your combined payments (deductible plus subsequent cost sharing) total $4,000. From that point until the plan year resets, your insurer covers 100% of covered, in-network services. The deductible is part of the out-of-pocket maximum, not a separate cost on top of it.
Annual Limits and How They Reset Each Year
Out-of-pocket maximums reset at the start of each plan year, not necessarily on January 1. Many employer plans and marketplace plans do reset on January 1, but some employer plans follow a different plan year start date such as July 1 or the company’s fiscal year. When the plan year resets, your accumulated deductible, copays, and coinsurance totals return to zero, and you start fresh.
The reset means you could reach your out-of-pocket maximum in December, receive free coverage for a few weeks, and then owe cost sharing again starting in January when the new plan year begins. If you have ongoing treatment or scheduled procedures, the timing of the reset can affect your total annual costs across two plan years. Surgery in late December and follow-up care in early January may require you to meet deductibles and pay cost sharing in both years, even though the care is part of one medical episode.
What changes at the plan year reset: Your deductible resets to zero, and you begin paying the full deductible amount again for covered services. Your accumulated copays and coinsurance reset to zero, and cost sharing restarts from the beginning. Your out-of-pocket maximum resets, meaning even if you hit the cap in the prior year, you’re no longer protected and must pay cost sharing again until you reach the new year’s maximum.
Final Words

FAQ
Q: What is the difference between a deductible and an out-of-pocket maximum?
A: The difference between a deductible and an out-of-pocket maximum is that the deductible is what you pay before most insurance starts paying, while the out-of-pocket maximum is the yearly cap on what you’ll pay total.
Q: What happens when I reach my out-of-pocket maximum? Does insurance cover 100% after out-of-pocket max? Will I ever have to pay more than out-of-pocket maximum?
A: When you reach your out-of-pocket maximum, your insurance pays 100% of covered in-network services for the rest of the plan year. You still pay premiums, out-of-network bills, and non-covered services.
