A deductible is the dollar amount you're responsible for paying toward covered health services before your insurance begins to pay its share. Once you've paid enough in eligible expenses to hit the deductible, the plan typically starts covering a percentage of costs through coinsurance, or a flat fee through copays, depending on the service.

  • Deductibles usually reset once a year, often on January 1 or your plan's renewal date.
  • Many plans exempt certain services, like preventive care, from the deductible entirely.
  • Family plans often have both an individual deductible and a higher family deductible.

Deductibles interact closely with premiums: plans with lower premiums often have higher deductibles, and vice versa. They also interact with the out-of-pocket maximum, since money you pay toward your deductible generally counts toward that yearly cap.

A frequent point of confusion is assuming every visit is subject to the deductible. Preventive services like annual checkups and many vaccines are typically covered at no cost even before the deductible is met, under ACA rules.
