What Each Limit Actually Does

These two terms appear on every health insurance summary of benefits, and they're frequently confused — sometimes treated as the same thing. They're not. Each one controls a different stage of what you pay.

Your deductible is the dollar amount you must pay out of your own pocket for covered services before your insurance plan starts sharing the cost. If your deductible is $1,500, you pay the first $1,500 of covered medical expenses each plan year. After that, your insurer typically steps in through coinsurance or copays — meaning you both pay a share.

Your out-of-pocket maximum (sometimes called the out-of-pocket limit) is the most you'll ever pay for covered services in a single plan year. Once you reach it, your insurer pays 100% of covered costs for the rest of that year. It's a financial ceiling.

For a fuller breakdown of how copays and coinsurance interact with both of these limits, see our plain-English breakdown of all three cost-sharing terms.

CriterionDeductibleOut-of-Pocket Maximum
What it controls When insurer starts sharing costs When insurer covers 100% of costs
Applies at what stage Beginning of the plan year After deductible and cost-sharing accumulate
Typical dollar range (health plans) Lower (e.g., $500–$3,000) Higher (e.g., $3,000–$9,100)
Copays count toward it? Usually no (varies by plan) Usually yes
Coinsurance counts toward it? No (coinsurance starts after deductible) Yes
When you stop paying covered costs Never alone — triggers cost-sharing Yes — insurer pays 100% after this point
Resets annually? Yes Yes

How They Stack — Not Compete

One of the most important things to understand: these two limits work together, not in parallel. What you pay toward your deductible also counts toward your out-of-pocket maximum. They're not two separate buckets.

Here's a simplified example. Say your plan has a $1,500 deductible and a $5,000 out-of-pocket maximum. You have a hospital stay that generates $8,000 in covered costs.

  • You pay the first $1,500 (your deductible).
  • After that, you and your insurer split costs through coinsurance — say 20% yours, 80% theirs — until your total out-of-pocket spending hits $5,000.
  • Once you hit $5,000 total, your insurer covers the remaining covered costs at 100% for the rest of the year.

The $1,500 deductible you already paid counts as part of the $5,000 cap — so you're not starting from zero again after the deductible. Understanding this stacking structure is essential when you're comparing plan options. How deductibles, premiums, and coverage limits fit together explains the relationship between these numbers across a full policy.

What Counts — and What Doesn't

Not every dollar you spend on healthcare counts toward these limits. What qualifies depends on your plan, and the details matter.

Typically counts toward your deductible: Payments for covered services at in-network providers — doctor visits (when subject to the deductible), diagnostic tests, hospital stays.

Typically counts toward your out-of-pocket maximum: Your deductible, coinsurance payments, and copays for covered in-network services.

Typically does NOT count toward either limit: Monthly premiums, out-of-network costs (depending on your plan type), costs for services not covered by your plan, and amounts above a provider's allowed charge.

Family Plans Have Two Layers of Limits

Family health plans often have both individual and family deductibles and out-of-pocket maximums. An individual family member's costs may hit their own limit before the family limit is reached — triggering full coverage for that person while others continue paying cost-sharing. Check your Summary of Benefits to understand how embedded versus aggregate limits apply on your specific plan.

Because plan structures vary significantly, always read your plan's Summary of Benefits and Coverage (SBC) — a standardized document insurers are required to provide — to confirm exactly what counts toward your specific limits. If something is unclear, a licensed insurance agent or your plan's member services line can help clarify.
