Health insurance comes with a lot of unfamiliar terms, and the out-of-pocket maximum is one of the most important — because it sets a limit on what you pay. In plain English, an out-of-pocket maximum is the most you have to pay out of your own pocket for covered health care in a single plan year. Once you reach that limit, your plan pays the full cost of covered services for the rest of the year.
That limit is there to protect you from very large bills after a serious illness or injury. Without it, your share of costs could keep growing all year. With it, there is a ceiling — though how high that ceiling sits, and exactly what counts toward it, depends on your plan.
How an out-of-pocket maximum works
Think of your health costs in a year as filling a bucket. Each time you pay your share of a covered service — your deductible, your copays, your coinsurance — that payment goes into the bucket. When the bucket is full, you have reached your out-of-pocket maximum, and the plan takes over covered costs for the rest of the plan year.
Here is the usual order:
- You pay your deductible first on services that are subject to it.
- After the deductible, you share costs through copays (a fixed fee for a visit or prescription) or coinsurance (a percentage of the cost).
- All of those payments add up toward your out-of-pocket maximum.
- Once you hit the maximum, the plan pays covered services in full until the plan year resets.
The plan year usually runs for twelve months, but it does not always match the calendar year, so check your plan’s start and end dates. When a new plan year begins, the count resets to zero.
What counts toward the maximum — and what does not
Most plans count your deductible, copays and coinsurance for covered services toward the maximum. But not everything counts. The following commonly do not:
- Your monthly premium. Paying your premium keeps your cover active, but it usually does not count toward the out-of-pocket maximum.
- Care from providers outside your plan’s network, if your plan treats out-of-network care differently.
- Services your plan does not cover at all.
- Amounts above what your plan allows for a service, sometimes called balance billing, where that applies.
Because these details vary from plan to plan, the only reliable source for your own limit is your plan documents — the summary of benefits or the full policy wording.
Out-of-pocket maximum vs deductible: what is the difference?
The deductible and the out-of-pocket maximum are related but they are not the same thing. Your deductible is the amount you pay before your plan starts sharing costs. Your out-of-pocket maximum is the larger total limit on everything you pay for covered care in the year, including the deductible itself.
In other words, the deductible is an early milestone on the way to the maximum. You will normally reach your deductible well before you reach your out-of-pocket maximum, if you reach it at all. Many people in a healthy year never reach either limit.

How copays and coinsurance fit in
Copays and coinsurance are the two main ways you share costs after the deductible, and both usually count toward your out-of-pocket maximum. A copay is a fixed fee, for example for a doctor visit. Coinsurance is a percentage of the cost of a covered service. Either way, the amount you pay brings you closer to the yearly limit.

Family vs individual limits
Many plans have two limits: one for each individual person, and a higher one for the whole family. How the family limit works depends on the plan. In some plans, each family member only needs to reach their own individual limit before their covered care is paid in full. In others, the family must reach the combined family limit together. If you are choosing cover for a family, ask how the plan applies the limit — it makes a real difference to a household budget.
Does every country use an out-of-pocket maximum?
No. The term “out-of-pocket maximum” is most common in health plans in the United States, but the underlying idea — a yearly cap on what patients pay — exists in different forms in many countries. Some health systems cap patient charges per visit, per prescription or per year; others fund care mainly through taxes, so patients pay little or nothing at the point of care. Rules differ by country, and even within a country they differ by plan and provider, so never assume another country’s rules apply to your own cover. If you move countries or buy cover abroad, check how cost-sharing and yearly caps work there before you rely on them.
What to check before you choose a plan
When comparing plans, do not look at the out-of-pocket maximum on its own. Check it alongside these questions:
- How high is the individual limit, and is there a separate family limit?
- Does the plan count copays toward the maximum, or only the deductible and coinsurance?
- Are there services that are excluded from the limit, such as out-of-network care?
- Does the plan year match the calendar year, and when does the count reset?
- What is the monthly premium — a plan with a low maximum may charge a higher premium, and the trade-off matters.
A lower maximum gives you more protection against a very expensive year, but it is only one part of the total cost. Read it together with the premium, the deductible and the network of providers.
The bottom line
An out-of-pocket maximum is your yearly safety net: the most you pay for covered health care in a plan year, after which your plan pays covered costs in full. Know your limit, know what counts toward it, and check the plan wording rather than guessing — especially if you are comparing plans or moving between countries.
