For 2025, the ACA’s federal cap on annual out-of-pocket spending for marketplace plans is $9,100 for individual coverage or $18,200 for a family. Once you hit that limit, your insurance pays 100% of eligible in-network services for the rest of the calendar year. That’s the promise. The catch: “eligible in-network services” is doing a lot of work in that sentence, and what doesn’t count can surprise you.

The Short Answer

Your out-of-pocket maximum is the most you’ll pay each year for covered healthcare—specifically, the total of your deductible, copays, and coinsurance for in-network care. After you reach that annual limit, your insurer covers 100% of those same services for the remainder of the plan year. Premiums, out-of-network care, and excluded services don’t count toward the cap and don’t stop costing you money.

How the Out-of-Pocket Max Works: A Real Example

Here’s how the numbers actually add up over the course of a year. Let’s say you’re enrolled in a 2025 Silver marketplace plan with these details:

  • Monthly premium: $350
  • Deductible: $1,500
  • Office visit copay: $40
  • Coinsurance: 20% (you pay 20%, insurance pays 80% after you’ve met your deductible)
  • Out-of-pocket maximum: $6,000
ServiceBilled AmountWhat You PayRunning Total Toward OOP Max
Annual checkup (preventive)$250$0$0
Three office visits$120 each$40 copay × 3 = $120$120
Emergency room visit$500$500 (deductible not yet met)$620
Specialist visit$600$100 (rest of deductible) + $100 (20% of remaining $500)$820
Lab work$400$80 (20% coinsurance; deductible now met)$900
MRI scan$2,000$400 (20% coinsurance)$1,300
Surgery$23,500$4,700 (20% coinsurance)$6,000 ← OOP max reached
Follow-up imaging$1,500$0 (insurance pays 100%)$6,000
Physical therapy (6 sessions)$900$0 (insurance pays 100%)$6,000

Your total medical spending for the year: $6,000 out-of-pocket + $4,200 in premiums ($350/month) = $10,200. The $6,000 is capped by your out-of-pocket max. The premiums are separate and never count toward that limit.

Notice the preventive annual checkup cost you nothing and didn’t count toward your $6,000. That’s intentional—ACA preventive services are free regardless of whether you’ve met your deductible or out-of-pocket maximum.

What Counts Toward Your Out-of-Pocket Maximum

Healthcare.gov defines the out-of-pocket limit as the total you pay in cost-sharing for covered, in-network services. Here’s what rolls into that annual limit:

  • Your deductible: the amount you pay before insurance starts sharing the cost
  • Copays: fixed fees per visit or prescription (e.g., $40 office visit, $15 generic drug)
  • Coinsurance: your percentage of the bill after the deductible is met (commonly 20% or 30%)

All three add up to your out-of-pocket max. Once the sum hits the cap, you’re done paying your share for the year—at least for in-network covered care.

What Does NOT Count Toward Your Out-of-Pocket Maximum

This is where many people get blindsided. The following costs are not capped by your out-of-pocket maximum:

Expense TypeWhy It Doesn’t Count
Monthly premiumsPremiums are the price of having insurance; cost-sharing is separate.
Preventive careThese services (screenings, vaccines, contraception) are already free; there’s no cost-sharing to count.
Out-of-network careUnless it’s an emergency, out-of-network bills typically don’t apply to your in-network OOP max. You may pay the full amount.
Balance billingCharges above your plan’s allowed amount when you see an out-of-network provider.
Excluded servicesCosmetic surgery, experimental treatments, services your plan doesn’t cover.

If you rack up $15,000 in out-of-network specialist bills, that $15,000 does not bring you closer to your in-network $6,000 out-of-pocket max. You’re simply out $15,000 unless your plan has a separate out-of-network OOP limit (some PPO plans do, but it’s usually much higher).

The 2025 Federal Limits

Under the Affordable Care Act, insurers cannot set an out-of-pocket maximum higher than the federal cap. For 2025, those limits are:

  • Individual coverage: $9,100
  • Family coverage: $18,200

These limits apply to all ACA-compliant marketplace plans (Bronze, Silver, Gold, Platinum). Your specific plan may set a lower out-of-pocket max—Gold and Platinum plans often do—but it cannot go higher than the federal ceiling.

Medicare’s Out-of-Pocket Rules

Original Medicare (Part A + Part B) has no statutory out-of-pocket maximum. Hospital stays, specialist visits, and outpatient care all carry separate cost-sharing with no annual cap. This is why many Medicare beneficiaries buy Medigap policies to limit their exposure.

Medicare Advantage plans (Part C) are required to include an out-of-pocket maximum. For 2025, CMS sets the in-network cap at $8,850 for in-network care, though individual plans vary. Out-of-network OOP maximums on Medicare Advantage plans are typically much higher than the in-network limit.

Out-of-Pocket Max vs. Deductible vs. Annual Limit

These terms overlap in ways that confuse even seasoned insurance users. Here’s the breakdown:

TermWhat It MeansExample
DeductibleAmount you pay first, before insurance shares the cost$1,500 deductible = you pay the first $1,500 of eligible care each year
CoinsuranceYour percentage of the bill after you’ve met the deductible20% coinsurance = you pay $200 of a $1,000 MRI (insurance pays $800)
CopayFixed dollar amount per service$40 copay per office visit, regardless of the visit’s full cost
Out-of-Pocket MaximumTotal annual cap on deductible + copays + coinsurance$6,000 OOP max = once you’ve paid $6,000 total, insurance covers 100% of in-network care
Annual LimitOutdated; the ACA banned annual and lifetime dollar limits on essential health benefits in 2014Some plans still cap non-essential services (e.g., 20 chiropractic visits/year)

The key insight: your out-of-pocket max includes your deductible. If your deductible is $1,500 and your OOP max is $6,000, you have $4,500 left to spend in copays and coinsurance before you hit the cap.

The term “annual limit” is mostly historical. Before the ACA, insurers could cap how much they’d pay per year or per lifetime—say, $1 million for cancer treatment. Those limits are now illegal for essential health benefits. You may still see annual caps on non-essential services like acupuncture or routine foot care, but those are service-count limits (e.g., “12 visits per year”), not dollar limits.

The Critical Misconception: “100% Coverage” After Hitting the Max

Reaching your out-of-pocket maximum does not mean all healthcare is free for the rest of the year. You’re covered at 100% only for:

  • In-network providers
  • Covered services under your plan’s benefits
  • Medically necessary care (not cosmetic, experimental, or excluded treatments)

If you need a service your plan doesn’t cover—say, fertility treatments or bariatric surgery—you’ll pay the full cost even if you’ve already hit your $6,000 OOP max. If you see an out-of-network specialist without getting prior authorization, same story. The insurance claim may be denied entirely, leaving you with the bill.

This is why reading your plan’s Summary of Benefits and Coverage (SBC) matters. The SBC lists what’s covered, what requires prior authorization, and which services are excluded. It’s a legally required document, and it’s written in plain language precisely so you can predict what will and won’t count toward your out-of-pocket maximum.

How Plan Type Affects Your Out-of-Pocket Maximum

ACA marketplace plans come in four metal tiers: Bronze, Silver, Gold, and Platinum. All are capped at the federal $9,100/$18,200 limit, but in practice:

  • Bronze plans: lower premiums, higher deductibles, OOP maximums often at the federal cap ($9,100)
  • Silver plans: moderate premiums, moderate deductibles, OOP max typically $6,000–$8,000
  • Gold plans: higher premiums, lower deductibles, OOP max often $5,000–$6,500
  • Platinum plans: highest premiums, lowest deductibles, OOP max as low as $4,000–$5,000

If you expect high medical use—ongoing specialist care, planned surgery, chronic condition management—a Gold or Platinum plan’s lower out-of-pocket maximum can save you thousands, even after paying the higher monthly premium. If you’re healthy and rarely see a doctor, a Bronze HDHP with a high OOP max may cost you less overall because you’re not paying for coverage you don’t use.

What Happens When You Have Two Health Plans

If you’re covered by two plans—say, your employer’s plan and your spouse’s plan—the out-of-pocket maximum doesn’t double. Instead, the plans coordinate benefits: one is primary, one is secondary. Your out-of-pocket costs count toward the primary plan’s OOP max first. The secondary plan may cover some or all of what the primary plan didn’t, but you still hit the cap on the primary plan before costs drop to zero.

Dual coverage does not mean you can apply the same $5,000 deductible payment to two separate $6,000 OOP maximums. The same dollars count only once, against the primary plan.

Why Your Out-of-Pocket Max Varies by Insurer and State

The $9,100 federal cap is a ceiling, not a mandate. Insurers set their own OOP maximums at or below that limit, and they vary by:

  • Plan type (HMO, PPO, EPO)
  • Metal tier (Bronze, Silver, Gold, Platinum)
  • State regulations: some states impose lower caps or require specific cost-sharing rules
  • Insurer pricing strategy: one Silver plan in Texas might have a $7,000 OOP max; another Silver plan in the same ZIP code might have $8,500

When you shop on Healthcare.gov or your state’s marketplace, the plan-comparison tool shows each plan’s out-of-pocket maximum alongside the premium and deductible. Sort by OOP max if you want to cap your annual risk, even if it means paying more each month.

FAQ

What does “out-of-pocket maximum” mean in health insurance?

The most you’ll pay in a calendar year for covered in-network healthcare services. Once you hit that dollar amount, your insurance pays 100% of eligible in-network care for the rest of the year.

What’s the difference between deductible and out-of-pocket maximum?

Your deductible is what you pay before insurance starts sharing costs. Your out-of-pocket maximum is the total of your deductible, copays, and coinsurance combined. The OOP max is always higher than the deductible because it includes all your cost-sharing.

Do copays count toward the out-of-pocket maximum?

Yes, as long as the copay is for an in-network covered service. Every $40 office visit copay and every $15 prescription copay adds to your running total toward the OOP max.

What counts toward the out-of-pocket maximum?

Deductibles, copays, and coinsurance for in-network covered services. Out-of-network care, premiums, balance-billed amounts, and excluded services do not count.

What happens when you reach your out-of-pocket maximum?

Your insurer covers 100% of in-network covered services for the rest of the plan year. You still pay your monthly premium, and you’re still responsible for out-of-network or excluded services.


Your out-of-pocket maximum is the most important number on your health plan after the premium—it defines your worst-case annual cost if you actually use your insurance. But “worst case” assumes you stay in-network, stick to covered services, and understand what counts. Read your plan’s Summary of Benefits and Coverage, verify your providers are in-network, and budget for both your monthly premium and the possibility that you’ll hit that $6,000 or $9,100 cap. The math is predictable; the surprise bills come from the exclusions.

Not insurance or financial advice. Coverage, cost-sharing, and out-of-pocket limits vary by plan, state, and insurer. Always verify your specific plan’s terms in your policy documents or on your insurer’s website.
