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

Health insurance uses several cost-sharing tools at once. The deductible is the amount 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 the Affordable Care Act rules that apply to many U.S. plans.
Plan-year vs per-visit
Unlike many auto deductibles, a medical deductible usually accumulates across the plan year. After you meet it, you still may owe copays or coinsurance until you reach the out-of-pocket maximum.
Family plans may have individual and family deductibles. Embedded vs aggregate family deductibles change when coverage for one person begins. The Summary of Benefits and Coverage is the place to confirm the design.
What 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.
