Health Insurance Deductibles, Coinsurance and Maximum Limits

Once you understand the different parts of your health insurance costs you’ll want to know how these work together and what your out-of-pocket costs may be. Below are a few examples of how deductibles, coinsurance and maximum limits work together.

Example #1: Deductibles, Coinsurance and Out-of-pocket maximum

Your health plan has a:

  • $4,000 deductible
  • 25% coinsurance
  • Out-of-pocket maximum of $5,000

This means:

  • You must pay $4,000 toward your medical costs before your plan begins to cover costs.
  • After you pay the $4,000 deductible, your plan covers 75% of the costs, and you pay the other 25%.
  • When you've paid $5,000 out of your pocket toward your medical costs, your plan covers 100% of your costs until your "plan year" renews. A plan is good for 1 year.

When the next plan year begins, your deductible and coinsurance reset. You are once again responsible for the $4,000 deductible and 25% coinsurance.

Example #2: Coinsurance After You've Met Your Deductible

Let's say you fracture your hand while playing sports and you need an X-ray. If you've already met your annual $4,000 deductible, your coinsurance goes into effect. In this example, that means that your plan now pays for 75% of your benefits while you pay the other 25%.

Here's a break down of those costs:

  • The X-ray for your hand costs $200.
  • Your plan covers 75%, which is $150.
  • The amount you pay out-of-pocket cost, or your coinsurance, is $50.

Example #3: Maximum Limits

Your health plan sets a maximum limit for certain tests, procedures and medical services. This means that it will cover up to a certain amount for these services. These limits help lower costs for all members by keeping rates fair and reasonable.

Let's say your doctor charges more for the above hand X-ray.

  • Your health plan covers a maximum of $200 for an X-ray.
  • Your doctor charges $250.
  • You may have to pay the $50 difference.
