Understanding Your Health Insurance: Deductibles, Copays and Out-of-Pocket Maximums
In the most common structure, you pay a premium to keep coverage, then pay covered costs up to your deductible; after that you share costs through copays or coinsurance until you hit the out-of-pocket maximum, when the plan pays 100% of covered in-network care for the rest of the year. Many plans also cover some services, such as office visits with a copay, before the deductible, and some have a separate prescription deductible, so check your plan’s Summary of Benefits. For 2026, HealthCare.gov says a Marketplace plan’s out-of-pocket limit can be no more than $10,600 for an individual or $21,200 for a family.
Knowing these numbers turns a scary medical bill into a predictable one, which is a big part of Medical Wealth.
The five terms that matter
- Premium: what you pay each month to have the plan, whether or not you use care. It does not count toward your deductible or out-of-pocket maximum.
- Deductible: the amount you pay for covered services before the plan starts to pay. Most plans must cover recommended preventive care in-network at no cost, even before the deductible.
- Copayment (copay): a fixed amount, such as $30 for a doctor visit, usually paid at the time of service.
- Coinsurance: your percentage share, such as 20%, of the allowed amount after you meet the deductible.
- Out-of-pocket maximum: the most you pay for covered in-network services in a plan year. Deductibles, copays and coinsurance count toward it; premiums, uncovered services and most out-of-network care do not.
The “allowed amount” is the price your plan has agreed to pay, often far below the provider’s list price. Your share is based on the allowed amount, not the sticker price.
Worked example: a $10,000 hospital bill
Say your plan has a $2,000 deductible, 20% coinsurance and a $6,000 out-of-pocket maximum, and you have used no care yet this year. An in-network surgery has an allowed amount of $10,000.
| Step | You pay | Plan pays |
|---|---|---|
| First $2,000 (deductible) | $2,000 | $0 |
| Remaining $8,000 at 20% / 80% | $1,600 | $6,400 |
| Total | $3,600 | $6,400 |
Now suppose complications push the allowed amount to $40,000. The formula would give $2,000 + 20% of $38,000 = $9,600, but the out-of-pocket maximum caps you at $6,000. Every covered in-network dollar after that is paid by the plan until the year resets. Your premiums are on top of this.
Plan types: HMO, PPO and HDHP
- HMO: usually lower premiums; you generally stay in network and may need referrals to see specialists.
- PPO: more freedom to see specialists and out-of-network providers, usually for higher premiums. Out-of-network care costs more and may not count toward the same maximum.
- EPO and POS: hybrids that mix network rules from the two above.
- High-deductible health plan (HDHP): lower premiums and a higher deductible. A qualifying HDHP lets you contribute to a Health Savings Account, which offers tax advantages; see Roth vs Traditional (Plus HSA Basics).
For context, the KFF 2025 Employer Health Benefits Survey found the average family premium for employer coverage reached $26,993, with workers paying $6,850 of it. Among covered workers in plans with a general deductible, the average single-coverage deductible was $1,886, and 29% of covered workers were enrolled in HSA-qualified high-deductible plans.
How to compare plans
Compare total yearly cost, not just the premium: annual premiums plus what you expect to spend on care, with the out-of-pocket maximum as your worst case.
Example: Plan A costs $150 a month with a $4,000 deductible and a $7,000 maximum. Plan B costs $350 a month with a $500 deductible and a $3,000 maximum. In a light year, Plan A costs about $1,800 in premiums versus $4,200 for Plan B. In a worst-case year, Plan A totals $8,800 ($1,800 + $7,000) and Plan B $7,200 ($4,200 + $3,000). If you expect heavy care, Plan B may win; if not, Plan A usually does. Also check that your doctors and prescriptions are covered.
Your protection from surprise bills
The federal No Surprises Act, in effect since January 1, 2022, protects most people with health coverage from surprise out-of-network bills for most emergency care, for certain care from out-of-network providers at in-network hospitals and surgery centers, and for out-of-network air ambulances. In those cases your cost sharing cannot be higher than in-network rates.
If you are uninsured or paying yourself, you can ask for a good faith estimate, and you can dispute a bill that comes in $400 or more above it. Complaints go to CMS at 1-800-985-3059. Some states add extra protections.
Plan for your deductible and maximum
A health plan limits your risk; it does not remove it. A useful target is keeping at least your deductible, and ideally your out-of-pocket maximum, in cash. The Emergency Fund Calculator shows how many months your savings cover, and Emergency Funds 101 explains how to build that cushion. The Medical Wealth guide covers the rest of the picture.
Common questions
What is the difference between a deductible and an out-of-pocket maximum?
The deductible is what you pay for most covered care before your plan starts sharing costs, though many plans cover some services (such as copay visits or preventive care) before it, and some have a separate prescription deductible. The out-of-pocket maximum is the most you pay for covered in-network care in a year, including the deductible, copays and coinsurance.
What is the 2026 out-of-pocket maximum?
For the 2026 plan year, a Marketplace plan’s out-of-pocket limit can be no more than $10,600 for an individual and $21,200 for a family. Many plans set lower limits.
Do premiums count toward the out-of-pocket maximum?
No. Premiums are paid separately. The out-of-pocket maximum counts deductibles, copays and coinsurance for covered in-network services.
Is a copay the same as coinsurance?
No. A copay is a fixed dollar amount, such as $30 per visit. Coinsurance is a percentage of the allowed amount, such as 20%, usually after you meet your deductible.
