What Are Out-of-Pocket Medical Expenses? Costs and Caps

Out-of-pocket medical expenses are the healthcare costs you pay yourself, on top of your monthly premium and beyond what your insurance covers. They come in three main forms: your deductible, copayments, and coinsurance. Federal law caps the total you can spend on in-network covered care each year. For 2026, that cap is $10,600 for an individual and $21,200 for a family on Marketplace and most employer plans.¹ Some spending counts toward that ceiling, and some doesn’t, and the difference is where most surprise bills come from.

The Three Costs That Make Up Your Share

Deductible

Your deductible is the amount you pay for covered care before your insurer starts contributing. A $2,000 deductible means you cover the first $2,000 of covered services each plan year. The deductible resets every year, so if you’re close to meeting it in November, scheduling care before January can save you from starting over.

Copayment

A copay is a flat dollar amount for a specific service: $25 for a primary care visit, $50 for a specialist, $150 for an ER trip. The amount is usually printed on your insurance card, and you pay it at the time of service.² Some plans charge copays before you’ve met your deductible; others waive them for things like annual physicals or generic drugs.

Coinsurance

Coinsurance is your percentage share of a bill after you’ve met your deductible. The most common split is 80/20: your insurer pays 80%, you pay 20%. On a $10,000 surgery, that’s $2,000 from you.³ Lower-premium plans sometimes set coinsurance at 30% or 40%, so the monthly savings can disappear fast if you actually use the plan.

The Allowed Amount Gap

There’s a fourth cost that catches people off guard. If a provider charges $500 but your plan’s allowed amount for that service is $350, you can be billed for the $150 difference on top of your normal cost-sharing.⁴ In-network providers agree to accept the plan’s allowed amount as full payment, so this gap only appears with out-of-network care.

Preventive Care You Don’t Pay For

Not every visit creates a bill. Federal law requires most health plans to cover a set of preventive services with no copay, no coinsurance, and no deductible, as long as you use an in-network provider.⁵ The list includes immunizations, blood pressure and cholesterol screenings, cancer screenings like colonoscopies and mammograms, and well-child visits. If you get billed a copay for something that should be free, call your insurer. Billing errors on preventive care are common.

The Annual Out-of-Pocket Maximum

The out-of-pocket maximum is the single most important number in your health plan. Once your deductibles, copays, and coinsurance for in-network covered services hit this limit, your insurer pays 100% of covered care for the rest of the plan year.¹ The Affordable Care Act requires every non-grandfathered plan to include this cap, and it applies to all essential health benefits.⁶

For 2026, no Marketplace plan can set this limit higher than $10,600 for individual coverage or $21,200 for family coverage. Many employer plans and Silver or Gold Marketplace plans set theirs lower. High-deductible health plans that qualify for a Health Savings Account have a tighter cap: $8,500 for self-only coverage and $17,000 for family coverage in 2026.⁷

These numbers adjust every year with healthcare inflation. If you have a chronic condition or know a surgery is coming, a plan with a lower out-of-pocket maximum can save you thousands, even at a higher monthly premium.

What Doesn’t Count Toward the Cap

The annual limit sounds like a hard ceiling on your medical spending. It isn’t. Federal law specifically excludes three categories from counting toward it.⁶

Monthly premiums never count. Premiums are the price of having coverage, not of using it, and they keep flowing even in a year when you hit your out-of-pocket maximum in January.

Out-of-network balance billing doesn’t count either. When an out-of-network provider charges more than your plan’s allowed amount, the difference sits outside both your deductible and your annual cap.⁴ These extra charges are uncapped.

Non-covered services don’t count. Procedures your plan doesn’t cover at all, like most cosmetic surgery, are entirely yours to pay, and so is adult dental and vision care on plans that don’t include it. None of it moves you toward the maximum.

The practical lesson: staying in-network and confirming coverage before a procedure are the two things most likely to keep your spending inside the safety net.

Surprise Bill Protections

Since January 2022, the No Surprises Act has banned most surprise medical bills in situations where you had no real choice about who treated you. It covers three scenarios: emergency services at any hospital or freestanding emergency department, care from an out-of-network provider at an in-network facility (an anesthesiologist you didn’t pick, for example), and air ambulance services from out-of-network providers.⁸

When the law applies, your cost-sharing is calculated as if the provider were in-network, that amount counts toward your in-network deductible and out-of-pocket maximum, and the provider cannot bill you for the difference.⁹ If you’re uninsured or paying cash, providers must give you a good faith estimate before scheduled care, and you have the right to dispute a final bill that exceeds that estimate by $400 or more.

Accounts That Lower What You Actually Pay

Several accounts let you pay medical costs with pre-tax money, which effectively discounts every dollar you spend by your tax rate.

Health Savings Account (HSA)

An HSA is available if you’re enrolled in a qualifying high-deductible health plan. For 2026, you can contribute up to $4,400 for individual coverage or $8,750 for family coverage. To qualify, your HDHP needs a minimum deductible of $1,700 for self-only or $3,400 for family coverage, with out-of-pocket spending capped at $8,500 or $17,000.⁷

Contributions are tax-deductible whether or not you itemize, withdrawals for qualified medical expenses are tax-free, and unused funds roll over year after year.¹⁰ The account stays with you through job changes and into retirement.

Flexible Spending Account (FSA)

An FSA runs through your employer and is funded by pre-tax payroll deductions. The 2026 contribution limit is $3,400 for a healthcare FSA. The catch is use-it-or-lose-it: unused funds generally don’t survive the plan year. Your employer’s plan may offer one of two relief options, but not both. A grace period extends your spending deadline by up to two and a half months after the plan year. A carryover provision lets you roll up to $680 of unused funds into the next year.¹⁰ Anything above the carryover is forfeited, so estimate conservatively.

Health Reimbursement Arrangement (HRA)

An HRA is funded entirely by your employer. You don’t contribute from your paycheck. Your employer sets the amount and decides which expenses it covers. HRAs are often paired with high-deductible plans to help bridge the deductible. You don’t own the account, so the balance typically stays with the employer when you leave.

The Medical Expense Tax Deduction

If your unreimbursed medical costs are large enough relative to your income, you can deduct part of them on your federal return. The threshold is 7.5% of your adjusted gross income, and only spending above that line is deductible. You have to itemize on Schedule A to claim it.¹¹ At an AGI of $80,000, the first $6,000 in medical expenses yields no deduction. Only the amount above counts.

The list of qualifying expenses is wider than most people think. Beyond doctor visits, hospital stays, and prescriptions, it includes dental and vision care, mental health treatment, fertility procedures, hearing aids, prescribed weight-loss programs for a diagnosed condition, and the cost of buying and maintaining a service animal.¹² Health insurance premiums paid with after-tax dollars count, as do long-term care premiums up to age-based limits. Mileage driven for medical appointments is deductible at 20.5 cents per mile for 2026.¹³

The deduction is most useful in years with a major medical event. Some people deliberately bunch elective procedures into one calendar year to clear the 7.5% floor.

If You Can’t Pay a Hospital Bill

Facing a hospital bill you can’t afford? If it’s from a nonprofit hospital, federal law requires financial assistance. Under Section 501(r) of the Internal Revenue Code, every tax-exempt hospital must maintain a written financial assistance policy covering all emergency and medically necessary care. The policy has to state who qualifies for free or discounted care, how to apply, and what eligible patients will be charged.¹⁴

Hospitals must post these policies on their websites, display them in emergency rooms and admissions areas, and provide paper copies free of charge. Eligible patients cannot be charged more than the amounts generally billed to insured patients for the same care. Income thresholds are often more generous than people assume. Ask for an application before you agree to a payment plan or let the bill move toward collections.
