Two Numbers, Two Jobs
When you enroll in a health insurance plan, you'll encounter two figures that look similar but serve completely different functions: the deductible and the out-of-pocket maximum. Confusing them is one of the most common — and costly — misunderstandings policyholders make.
Think of them as two separate guardrails on the same road. The deductible marks where your insurer starts helping. The out-of-pocket maximum marks where your insurer takes over entirely. Neither number is the same as your monthly premium, and neither tells the full story on its own.
For a broader look at how these figures connect with your premium, see how premiums, deductibles, and out-of-pocket maximums work together.
| Criterion | Deductible | Out-of-Pocket Maximum |
|---|---|---|
| What it is | Amount you pay before insurer shares costs | Total annual cap on your covered cost share |
| When it applies | At the start of your policy year, per covered claim | Accumulates across the full policy year |
| What happens after you reach it | Insurer begins covering a share via copay/coinsurance | Insurer pays 100% of covered in-network costs |
| Typical dollar range (health plans) | Often $500–$7,000+ | Often $3,000–$9,100+ (ACA federal limit applies) |
| Does it include the other? | No — deductible is a subset of the out-of-pocket max | Yes — includes deductible, copays, and coinsurance |
| Resets each year? | Yes | Yes |
| Applies to out-of-network care? | Depends on the plan type | Often does not apply out-of-network |
How the Deductible Works
A deductible is the dollar amount you must pay out of your own pocket for covered services before your insurance plan begins to share costs. If your deductible is $1,500, you pay the first $1,500 in eligible medical expenses during the policy year — every dollar, without insurer assistance.
Once you clear that threshold, cost-sharing begins. Depending on your plan, this usually means you start paying a copay (a flat fee per visit) or coinsurance (a percentage of each bill). You're still paying something — just less, because your insurer is now contributing.
Not every service requires you to meet the deductible first. Many plans cover certain preventive services — like annual checkups or recommended screenings — before the deductible, meaning they're covered from day one. Always read your Summary of Benefits and Coverage to identify which services are deductible-exempt.

How the Out-of-Pocket Maximum Works
The out-of-pocket maximum (sometimes called the out-of-pocket limit) is the most you will ever pay for covered services in a single policy year. Once your total qualifying payments — including your deductible, copays, and coinsurance — reach that ceiling, your insurer pays 100% of covered in-network costs for the remainder of the year.
This is a meaningful protection against catastrophic medical bills. If you face a serious illness, surgery, or extended treatment, the out-of-pocket maximum caps your financial exposure at a known figure.
Not All Costs Count Toward Your Maximum
Even after you hit your out-of-pocket maximum, your insurer typically won't cover costs outside the plan's defined scope — such as out-of-network charges, non-covered services, or amounts above the plan's allowed rate. The maximum only shields you from cost-sharing on covered, in-network care. Review your plan's Summary of Benefits and Coverage document to confirm exactly which expenses count toward the limit.
Critically, your deductible spending counts toward your out-of-pocket maximum — they are not two separate tallies. If your deductible is $1,500 and your out-of-pocket maximum is $5,000, you only need to accumulate $3,500 more in cost-sharing after your deductible to reach the ceiling.

What These Numbers Don't Cover
Both figures apply only to covered, in-network services under most plans. Costs that typically fall outside both caps include:
- Premiums — your monthly payment to maintain coverage
- Out-of-network care (under many plan types)
- Services your plan explicitly excludes
- Costs above a plan's allowed amount for a given service
This distinction matters enormously if you receive care from a provider outside your plan's network. Out-of-network bills may not count toward either your deductible or your out-of-pocket maximum, leaving you with uncapped exposure. See how in-network vs. out-of-network care affects your real costs for a full explanation.
Both numbers also reset annually. Whatever progress you made toward your deductible or out-of-pocket maximum in the current policy year starts over at zero when the new year begins — a timing consideration worth tracking if you have scheduled procedures near year's end.

ACA individual out-of-pocket maximum (2024)
The Affordable Care Act sets an annual federal ceiling on out-of-pocket costs for individual marketplace and employer-sponsored plans; this figure is adjusted periodically by the Department of Health and Human Services.
$18,900
ACA family out-of-pocket maximum (2024)
Family plans are subject to a combined limit roughly double the individual cap, though individual family members may also have embedded individual limits depending on the plan.
