What Is Coinsurance?

Understanding what your healthcare costs mean for your plan

Key Takeaways

  • CoinsuranceCoinsurance is the percentage of your medical costs that you pay after you meet your deductible. The remaining amount is paid by your insurance company.

Your insurance company will cover the final $800. is a percentage of a medical cost split between you and your insurance company.

What is Coinsurance?

Coinsurance is a cost-share between you and your health insurance company. The rate is a percentage of a total medical bill split between you and your insurer. For example, your insurance plan may cover 80% of the cost, while you’re responsible for the remaining 20%. 

You are usually required to pay coinsurance costs after you’ve met your deductible and before you’ve reached your out-of-pocket maximum amount. Coinsurance generally applies if you select doctors and hospitals within your health plan’s network. Costs could be higher if you use out-of-network healthcare providers.

How Does It Work?

Here’s an example of when coinsurance rates may apply:

  • Deductible: $1,000
  • Coinsurance: Insurance pays 80%, while you pay 20%
  • Out-of-pocket Annual Maximum: $3,000

Let’s say you were sick with the flu at the beginning of the year, and admitted to the hospital. Your stay cost $1,000. You’ll pay the full $1,000 to reach your deductible. 

In the same year, you broke your leg. This time, your bill is for $2,500. Because you met your deductible earlier in the year, you’re only responsible for 20% of the bill until you reach your out-of-pocket maximum.

Here’s the cost breakdown:

  • Total medical bill: $2,500
  • Your health insurer pays 80%: $2,000
  • You then owe 20% of coinsurance: $500

After two hospital visits, you’ve paid $1,500 of your out-of-pocket costs for the year. Your coinsurance costs (20% for you and 80% from your insurance plan) will continue until you’ve reached your out-of-pocket limit of $3,000. 

What’s the Difference Between Coinsurance and Copays?

Coinsurance and copays are two different ways insurance companies pass on service costs to you. Generally speaking, a copay is a flat rate you pay at the time of service for care, and it applies immediately. Coinsurance usually begins after you have met your deductible.

To explain, here’s an example:

When you visit the doctor, you pay a flat rate called a copay. For example, while a primary care visit may cost $180, you only pay your copay amount for the visit. If your copay for a primary care visit is $20, you pay $20 instead of the $180.

Coinsurance is a percentage split in the cost between you and your insurance company. This takes effect after you’ve met your deductible. For example, if your deductible is $1,000, you pay 100% of your costs until you reach $1,000. After you reach $1,000, you may only be responsible for 20% of your costs (if your plan has an 80/20 coinsurance). This means, after your deductible, you pay 20% and insurance pays 80%.

To explain, let’s use an easy example. If you have a $20 copay and 80/20 coinsurance for a doctor visit that costs $180:

  • Your copay would be $20
  • Your coinsurance would be $180 before your deductible is met, and $36 after your deductible is met


Is it better to have a copay or coinsurance?

There’s not a right or wrong answer to determining whether coinsurance or copays are better. Everyone has different healthcare and financial needs. However, there are some pros and cons to each type of payment. 

In general, plans with lower monthly premiums tend to have higher coinsurance rates and vice versa. More cost-sharing benefits can make premiums higher. If you visit the doctor often or need prescription drugs regularly, consider higher premiums to cover more of your care.

It’s also important to consider all of your costs when deciding on your health plan. Copays usually don’t count toward health insurance deductibles or out-of-pocket maximums. However, you can get a better estimate of how much care will cost with copays as there’s usually a set price for doctor visits. You may not know your coinsurance cost until after receiving care.

Where can I get coinsurance?

You can find plans with coinsurance in the Health Insurance Marketplace or connect with a GoHealth licensed insurance agent to find a policy for your lifestyle and budget.

How much will coinsurance cost if I have a Marketplace plan?

The insurance company will determine coinsurance based on your level of coverage. Your Marketplace policy is categorized by category (gold, silver, bronze), also called metal tiers. The tiers represent coverage, and not the quality of care. [1]
