How do deductibles, coinsurance and copays work?

This information will help you if you're shopping for health insurance and have questions about how it works.

When both you and your health insurance company pay part of your medical expense, it’s called cost sharing. Deductibles, coinsurance and copays are all examples. Understanding how they work will help you know when and how much you have to pay for care. 

Deductible

  • A deductible is the amount you pay for health care services before your health insurance begins to pay.

Let's say your plan's deductible is $1,500. That means for most services, you'll pay 100 percent of your medical and pharmacy bills until the amount you pay reaches $1,500. After that, you share the cost with your plan by paying coinsurance and copays.

Coinsurance

  • Coinsurance is your share of the costs of a health care service. It's usually figured as a percentage of the total charge for the service. You start paying coinsurance after you've paid your plan's deductible.

Here's how it works. Lisa has allergies, so she sees a doctor regularly. She just paid her $1,500 deductible. Now her plan will cover 70 percent of the cost of her allergy shots. Lisa pays the other 30 percent; that's her coinsurance.

Copay

  • A copay is a fixed amount you pay for a health care service, usually when you receive the service. The amount can vary by the type of service. You may also have a copay when you get a prescription filled.

For example, a doctor’s office visit might have a copay of $30. The copay for an emergency room visit will usually cost more, such as $250. For some services, you may have both a copay and coinsurance.

What does this mean for me?

When choosing a plan, think about how much you use your insurance and how much protection you want against unpredictable expenses. Then look at the plan's deductible, coinsurance and copays and find what works best for you. Here are a few things to consider.

  • Deductible: A plan with a high deductible will have cheaper monthly payments. But you'll pay a lot upfront when you need care. You can also look for plans that cover some services before you pay your deductible.
  • Coinsurance: Typically, the lower a plan's monthly payments, the more you'll pay in coinsurance. 
  • Copays: If you visit your doctor or pharmacy often, you might want to choose a plan that has a low copay for office visits and prescriptions.
