A deductible in health insurance is the set amount you must pay out of pocket for covered medical services each year before your health plan starts sharing the costs.

Plain-language meaning

Think of a deductible as your “entry fee” into your health coverage for the year.

  • Until you’ve paid that deductible amount in eligible medical bills, you usually pay the full allowed cost yourself.
  • After you hit the deductible, your plan starts paying a big share, and you typically owe only copays or coinsurance for covered care.

Simple example

  • Say your plan has a $1,000 deductible.
  • You get a covered procedure that (after insurance discounts) costs $2,000.
  • You pay the first $1,000 (your full deductible), and then insurance starts paying its share of the remaining $1,000.

From that point on, for the rest of the year, you generally just pay copays/coinsurance for covered services until you reach your out‑of‑pocket maximum.

Important details

  • Deductibles usually reset every year, so you start back at $0 at the beginning of a new plan year.
  • Preventive services (like many vaccines and annual checkups) are often covered even if you haven’t met your deductible.
  • High-deductible health plans (HDHPs) have larger deductibles but often lower monthly premiums and can be paired with HSAs.

How it fits with other costs

  • Premium : What you pay every month to keep your coverage active, even if you never see a doctor.
  • Deductible : What you pay first for covered care each year before cost‑sharing kicks in.
  • Copay/coinsurance : Your share of the bill after the deductible is met.
  • Out-of-pocket maximum : A yearly cap; once your payments hit this number, the plan pays 100% of covered services for the rest of the year.

If you share your deductible amount and whether your plan is “high deductible” or not, a more tailored breakdown can be given for your situation.
