The out-of-pocket maximum in health insurance is the most you’ll pay for covered in-network medical care during a plan year. Once your spending on the deductible, copayments, and coinsurance reaches that ceiling, your insurer pays 100% of covered costs for the rest of the year. For 2026, federal law caps this limit at $10,600 for individual coverage and $21,200 for family coverage on ACA-compliant plans, though many plans set theirs lower.1HealthCare.gov. Out-of-Pocket Maximum/Limit
How the Limit Actually Works
Think of it as the finish line at the end of a sequence of cost-sharing steps. First you pay the deductible, the amount you owe before the plan starts sharing costs. After that, you enter a coinsurance phase where you split covered charges with your insurer at a set ratio. An 80/20 plan means the insurer pays 80% and you pay 20%. Flat copayments for doctor visits and prescriptions chip in throughout the year.
Every dollar you spend on the deductible, coinsurance, and copayments for in-network covered services counts toward the maximum. When your running total hits the plan’s limit, you stop paying for covered in-network care entirely and the insurer covers the rest through the end of the plan year. For a major surgery, an extended hospital stay, or ongoing treatment for a chronic condition, this is the mechanism that keeps bills from spiraling without limit.
ACA-compliant plans also cover certain preventive services at no charge to you, regardless of whether you’ve met the deductible. Because you pay nothing, those visits don’t move you closer to your maximum. Routine screenings, vaccinations, and annual wellness visits fall into this category.
What Counts and What Doesn’t
This is where most confusion arises. Only certain spending gets you closer to the finish line.
Spending that counts:
- Deductible payments
- Copayments for covered services
- Coinsurance on covered services after the deductible
Spending that doesn’t:
- Monthly premiums
- Out-of-network care, unless a specific protection applies
- Services your plan excludes from coverage
- Balance-billed amounts above what your insurer considers reasonable
The premium exclusion trips people up most often. You might pay $500 a month to keep the plan active and $3,000 in medical bills over the year, but only the $3,000 moves you toward the limit.1HealthCare.gov. Out-of-Pocket Maximum/Limit
Prescription drugs can also create tracking headaches. Most ACA-compliant plans fold prescription costs into the same maximum, but some run a separate prescription drug limit that doesn’t talk to the medical one. Medications outside your plan’s formulary usually count toward neither. Your plan’s summary of benefits will show which setup applies.
2026 Federal Caps
The ACA ties the ceiling to a formula that adjusts each year for healthcare cost growth. For the 2026 plan year, no Marketplace or ACA-compliant plan can set an out-of-pocket maximum higher than $10,600 for an individual or $21,200 for a family.1HealthCare.gov. Out-of-Pocket Maximum/Limit Insurers can set lower limits, but they can’t go above these caps for essential health benefits. Employer-sponsored plans generally follow the same federal caps.
High Deductible Health Plans
If you have a high deductible health plan paired with a health savings account, a separate set of federal rules applies. For 2026, an HDHP must have a minimum annual deductible of $1,700 for self-only coverage or $3,400 for family coverage, and its out-of-pocket maximum cannot exceed $8,500 for self-only or $17,000 for family coverage.2IRS. Revenue Procedure 2025-19 Those HDHP caps sit below the general ACA numbers, so people on these plans hit the insurer-pays-everything stage sooner, even though they face higher upfront costs before coinsurance starts.
Family Plans: Embedded vs. Aggregate
Family plans add a layer of complexity, because the maximum can be structured in two ways and the difference can cost thousands depending on how your family uses care.
An aggregate limit sets a single collective ceiling for the whole family. No one member’s spending triggers full coverage on its own. Everyone’s costs pool together, and the insurer only starts covering 100% once the combined total hits the family limit. If one family member has a $9,000 surgery but the family ceiling is $21,200, the family is still on the hook for more cost-sharing.
An embedded limit includes both an individual and a family cap. Each family member has their own individual ceiling. Once one person’s costs reach that individual limit, the insurer covers 100% of that person’s care for the rest of the year, even if the family total hasn’t been reached. Under ACA rules, no single person on a family plan can be required to pay more than the individual limit ($10,600 for 2026).1HealthCare.gov. Out-of-Pocket Maximum/Limit That protection prevents one family member’s catastrophic illness from consuming the entire family limit and leaving nothing for anyone else.
When comparing family plans, check which structure applies. An aggregate plan with a lower headline limit might look cheaper on paper but leave a single family member exposed to more cost-sharing than an embedded plan would.
Surprise Bills and the No Surprises Act
One of the biggest historical gaps in out-of-pocket protection was surprise medical billing. You could visit an in-network hospital and still get hit with out-of-network charges from an anesthesiologist or radiologist you never chose, and those charges wouldn’t count toward your in-network maximum. The No Surprises Act closed that gap starting in 2022.
Under the law, your cost-sharing for emergency services from out-of-network providers cannot exceed what you’d pay in-network for the same care. The same rule applies to non-emergency services from out-of-network providers at in-network facilities and to out-of-network air ambulance services. Those cost-sharing payments count toward your in-network deductible and in-network maximum as if an in-network provider had treated you.3Office of the Law Revision Counsel. 42 U.S. Code 300gg-111 – Preventing Surprise Medical Bills The provider and insurer settle any remaining billing dispute between themselves.4U.S. Department of Labor. Avoid Surprise Healthcare Expenses: How the No Surprises Act Can Help
Outside those protected scenarios, out-of-network care still generally sits outside your in-network maximum. Some plans maintain a separate, higher out-of-network limit; many don’t cover out-of-network care at all except in emergencies. Elective and non-essential procedures, cosmetic surgery, most fertility treatments, and experimental therapies typically fall outside coverage entirely, so spending on them never moves the needle.
When the Counter Resets
Your out-of-pocket total resets to zero at the start of each new plan year. For most employer-sponsored plans and all Marketplace plans running on the calendar year, that happens on January 1. Some employer plans run on a fiscal year, in which case the reset aligns with that schedule instead.
The reset matters for anyone with expensive ongoing care. If you reach the maximum in October, you get two months of fully covered care before the counter starts over. Scheduling elective procedures late in the plan year after you’ve already hit the ceiling can save thousands compared with booking them right after a reset. If you know heavy expenses are coming, front-loading care early in the plan year gets you to the maximum sooner and buys more months of full coverage.
Fixing Errors in Your Tally
Insurers sometimes get the math wrong. Claims get processed incorrectly, cost-sharing doesn’t get credited, or copayments keep getting charged after you’ve already hit the limit.
Start with your explanation of benefits statements, which show how each claim was processed and what was applied toward the maximum. If the numbers don’t match your records, contact your insurer to request a correction, and keep copies of all bills, receipts, and EOBs so you can prove what you’ve paid. If informal resolution fails, file a formal internal appeal in writing with supporting documentation. Your insurer has to complete the internal appeal within 30 days for services you haven’t received yet, or 60 days for services already provided.5HealthCare.gov. Internal Appeals
If that doesn’t resolve the issue, you can request an external review by an independent third party. The insurer is legally bound by the external reviewer’s decision.6HealthCare.gov. How to Appeal an Insurance Company Decision External reviews follow federal regulatory guidelines, and many states run consumer assistance programs that can help at no cost.7eCFR. 45 CFR 147.136 – Internal Claims and Appeals and External Review Processes For patterns of noncompliance, a complaint to your state insurance department can trigger a regulatory investigation and corrective action.
