These are two of the most important — and most confused — health insurance terms. Both limit how much you pay for healthcare, but they work very differently.
Deductible — The amount you pay for covered healthcare services before your insurance starts paying. After you meet your deductible, you typically pay only a copay or coinsurance for covered services, and the insurance company pays the rest.
Example: You have a $2,000 deductible. You break your arm and the ER visit costs $5,000. You pay the first $2,000. Your insurance then pays its share of the remaining $3,000 (let's say 80%, or $2,400). You pay the remaining 20% ($600). Total out-of-pocket on this visit: $2,600.
Out-of-Pocket Maximum (OOP Max) — The most you'll pay in total for covered services in a calendar year. Once you've spent this amount, your insurance pays 100% of covered services for the rest of the year.
Example, continued: If your OOP max is $8,000 and you've already spent $2,600 on the ER, you'd need to spend another $5,400 before your insurance pays everything. If you have a major surgery later in the year that brings you to $8,000, every covered service after that costs you $0 until next January 1.
What counts toward each:
| Cost | Counts toward deductible? | Counts toward OOP max? |
|---|---|---|
| Deductible payments | ✓ | ✓ |
| Copays (after deductible) | (Already past it) | ✓ |
| Coinsurance (your % share) | (Already past it) | ✓ |
| Premium (monthly payment) | ✗ | ✗ |
| Out-of-network care (HMO) | ✗ (often not covered at all) | ✗ |
| Non-covered services (cosmetic, etc.) | ✗ | ✗ |
Important: Your monthly premium does NOT count toward either. Premium is what you pay just to have the insurance.
2026 limits (federal maximums for ACA-compliant plans):
- Maximum out-of-pocket for in-network: $9,200 single / $18,400 family
- Maximum deductible: also $9,200 (some Bronze plans hit this)
- Cost-sharing reduction (CSR) Silver plans for income under 250% FPL drop these dramatically
Medicare specific:
- Original Medicare has a Part A deductible ($1,736 in 2026, per benefit period not annual) and Part B deductible ($283/year)
- Original Medicare has no OOP max — this is why Medigap is popular (it covers the gaps)
- Medicare Advantage plans MUST have an OOP max, capped at $9,350 for in-network in 2026 (lower in many plans)
- Part D drug plans now have a $2,000 OOP max in 2026 (new, separate from medical OOP max)
Strategy for plan choice:
- High deductible, low premium plans (Bronze, HSA-eligible): Best if you're healthy and rarely use care. You're betting against catastrophic events. The OOP max is your worst-case-scenario protection.
- Low deductible, higher premium plans (Gold, Platinum): Best if you have predictable care needs. You pay more upfront monthly but face fewer surprise bills.
- CSR Silver (under 250% FPL only): Almost always the best total value because the deductible AND OOP max are dramatically reduced — sometimes even below Gold-tier — while you only pay a Silver premium.
The HSA combo (with HDHP/Bronze):
- High Deductible Health Plan (HDHP) with HSA-eligibility
- Tax-free contributions to an HSA can prefund your deductible
- 2026 HSA contribution limits: $4,300 single / $8,550 family
- Triple tax advantage: deductible going in, no tax on growth, tax-free for medical withdrawals
