Answer

What do deductible, copay, coinsurance, and out-of-pocket maximum mean?

The short answer

Your premium is what you pay to have the plan. For care, you often pay the deductible first. Then you may pay a copay (a set amount) or coinsurance (a percentage). The out-of-pocket maximum is the most you pay for covered, in-network care in a year.

Key takeaways

  • Premiums keep your coverage active. They usually do not count toward your deductible.
  • Some services, such as many preventive visits, may be covered before you meet your deductible.
  • After you reach the out-of-pocket maximum, the plan pays 100% of covered in-network care for the rest of the plan year.

What you can do next

  1. Find your plan's Summary of Benefits and Coverage and write down the four numbers.
  2. Check your plan website for how much of your deductible you have met this year.
  3. Use your next EOB to see which part of the cost went to the deductible, copay, or coinsurance.
