How Health Insurance Deductibles Work
A health insurance deductible is what you generally pay for covered services before the plan starts sharing costs. See how it interacts with copays, coinsurance, and the out-of-pocket maximum.

Health insurance stacks several cost-sharing tools at once. The deductible is what you typically pay for covered services each plan year before coinsurance begins. Some services — such as certain preventive care — may be covered before the deductible under Affordable Care Act rules that apply to many U.S. plans.
Plan-year accumulation
Unlike many auto deductibles, a medical deductible usually builds across the plan year. After you meet it, you may still owe copays or coinsurance until you reach the out-of-pocket maximum.
Family plans may have individual and family deductibles. Embedded versus aggregate designs change when coverage for one person begins. The Summary of Benefits and Coverage is the place to confirm the design.
Amounts that may not count
Premiums generally do not count toward the deductible. Out-of-network care, non-covered services, and amounts above allowed charges may not count either. Copays sometimes apply before the deductible; plan designs differ.
High-deductible plans
High-deductible health plans (HDHPs) can pair with health savings accounts when IRS rules are met. Contribution limits, qualifying deductibles, and eligible expenses change over time. Use IRS and plan documents for the current year rather than a general article.
