You have health insurance, yet the bill for your visit or scan came back in full. In most cases, the reason is your deductible.

A deductible is the amount you pay for covered health care services before your insurance plan starts to pay. Most people with job-based coverage have one: in the 2025 KFF Employer Health Benefits Survey, 88% of workers with single coverage had a general annual deductible, and the average was $1,886.

This guide answers what is a deductible in health insurance, how it works during the year, whether copays count, and how family deductibles and resets work.

What is a deductible in health insurance?

HealthCare.gov's example: with a $2,000 deductible, you pay the first $2,000 of covered services yourself. After you pay your deductible, you usually pay only a copayment or coinsurance for covered services, and your insurance company pays the rest.

That's the short answer to what is a deductible in health insurance. It's your share at the start of each plan year, before cost-sharing begins.

Deductible size is tied to your premium. Plans with lower monthly premiums generally have higher deductibles, and plans with higher premiums usually have lower ones. High deductibles are common: KFF found 34% of covered workers in 2025 were in a plan with a general annual deductible of $2,000 or more.

For how the deductible fits with premiums, networks and prior authorization, see our guide to how health insurance works.

How a deductible works over a plan year

The easiest way to see how a deductible works is to follow one person through a year. This example on HealthCare.gov uses a plan with a $1,500 deductible, 20% coinsurance and a $5,000 out-of-pocket maximum. Each office visit costs $125.

• In February, Jane hasn't met her deductible. She pays the full $125 and the plan pays $0.
• In May, she reaches her deductible. Now she pays 20% coinsurance, or $25 per visit, and the plan pays $100.
• By October, she has paid $5,000 in total, her out-of-pocket maximum. The plan pays the full $125 for covered services through the end of the coverage period.

So what does it mean to meet your deductible? It means you've paid that amount for covered services this plan year. What happens after you meet your deductible is the middle stage: you share costs through copays or coinsurance until you hit the out-of-pocket maximum.

That maximum is the cap on your yearly spending. Our guide to how health insurance works explains it in more detail.

Copay vs deductible: do copays count toward it?

A deductible is a running total you pay first. A copayment is a fixed amount, such as $20, that you pay for a covered service after you've paid your deductible.

HealthCare.gov shows how the two interact. If the plan's allowed amount for an office visit is $100 and your copay is $20, you pay $20 once your deductible is met. If you haven't met it, you pay the full $100.

Many plans do pay for certain services, like a checkup, before you've met your deductible. In some plans, that means you pay only a copay for an office visit early in the year. Whether that copay also counts toward the deductible depends on your plan, so the answer to "do copays count towards deductible" is in your Summary of Benefits and Coverage.

One rule is consistent. Copays and coinsurance for covered, in-network care count toward your out-of-pocket maximum.

What counts toward your deductible and what doesn't

Not every dollar you spend on health care moves you toward your deductible. In general:

• Your monthly premium never counts.
• Marketplace plans cover certain preventive services, such as many screenings and shots, at no cost in network, even before you meet your deductible.
• Some plans have a separate deductible for prescription drugs, so drug costs may not count toward your medical deductible.
• Services your plan doesn't cover don't count.

If you're asking "do prescriptions count toward my deductible," look for a separate pharmacy deductible in your plan documents.

Individual and family deductibles: embedded vs aggregate

Family plans often have both an individual deductible, which applies to each person, and a family deductible, which applies to all family members. How the two work together depends on whether the plan's deductible is embedded or aggregate.

A KFF Health News explainer on family deductibles describes both:

• An aggregate deductible is one deductible for the whole family. A family with a $3,000 deductible pays the full $3,000 together before the plan starts paying.
• An embedded deductible puts a separate deductible for each person inside the family deductible. In the same $3,000 plan, each member might have a $1,000 deductible. If one person has large bills, the plan starts paying for that person after they reach $1,000, even if the family hasn't reached $3,000.

The embedded vs aggregate deductible difference matters most when one family member needs surgery or ongoing care. Your plan documents say which type you have.

When your annual deductible resets

Your annual deductible starts over at the beginning of each plan year. A plan year is a 12-month period of coverage, and it may not match the calendar year. Check your plan documents or ask your employer when yours begins.

The reset date can affect planning. If you've met most of your deductible and a non-urgent procedure is on the table, ask your insurer how much is left and when the year ends. Our list of questions to ask your surgeon can help you plan the timing.

High-deductible plans and Medicare

A high-deductible health plan works with a Health Savings Account, which lets you set aside pre-tax money to pay deductibles, copays and coinsurance. For 2026, HealthCare.gov lists the minimum deductible for these HSA-eligible plans as $1,700 for self-only coverage and $3,400 for a family. For 2027, it's $1,750 and $3,500.

Medicare uses deductibles too, with its own rules. According to Medicare.gov's cost page, the 2026 Part B deductible is $283 a year. Part A charges $1,736 for each inpatient hospital benefit period, so you may pay it more than once in a year.

Know your numbers before you book care

Your deductible is the first piece of your share each year. Before a planned procedure, ask your insurer how much of your deductible is left, whether copays count toward it, and when your plan year ends. If you're comparing settings, our guide to outpatient vs inpatient surgery can help.
