What Is Coinsurance?
Coinsurance is the percentage of medical costs you pay after meeting your health insurance deductible.
Instead of paying a fixed amount, you share the cost of healthcare services with your insurance company.
Example
Imagine:
- Medical bill: $2,000
- Deductible already met
- Coinsurance: 20%
You pay:
20% of $2,000 = $400
Insurance pays:
80% = $1,600
The higher the medical bill, the more you’ll pay under coinsurance.
What Is a Copay?
A copay (or copayment) is a fixed amount you pay for a covered healthcare service.
The amount does not change regardless of the total medical bill.
Examples include:
- $20 for a doctor’s visit
- $15 for prescription medicine
- $40 for a specialist
- $100 for emergency room visits
Copays make healthcare costs easier to predict.
Coinsurance vs Copay: Comparison Table
| Feature | Coinsurance | Copay |
|---|---|---|
| Payment Type | Percentage | Fixed Amount |
| Paid After Deductible | Usually Yes | Sometimes No |
| Cost Predictability | Lower | Higher |
| Best For | Major treatments | Routine healthcare |
| Amount Changes | Yes | No |
| Example | 20% of bill | $30 doctor visit |
How Coinsurance Works
Coinsurance begins only after you’ve met your deductible.
For example:
Annual deductible: $1,500
Hospital bill: $10,000
Coinsurance: 20%
You pay:
- First $1,500 deductible
- Then 20% of remaining bill
Insurance covers the remaining 80%.
Most plans also have an out-of-pocket maximum, which limits the total amount you pay each year.
How Copays Work
Copays are straightforward.
Every time you visit a healthcare provider, you pay a predetermined amount.
Examples:
- Family doctor: $25
- Pediatrician: $20
- Specialist: $50
- Generic medication: $10
Your insurance company covers the remaining cost.
Sarah has health insurance with:
- Deductible: $1,000
- Coinsurance: 20%
- Copay: $30
Doctor Visit
Doctor charges: $180
Sarah pays:
Copay = $30
Insurance pays the rest.
Surgery
Hospital charges: $12,000
Sarah has already met her deductible.
She pays:
20% = $2,400
Insurance pays:
80% = $9,600
This example shows why major medical procedures usually involve coinsurance rather than just a copay.

Conclusion
Coinsurance and copays are both important parts of health insurance, but they serve different purposes. A copay provides predictable, fixed costs for routine healthcare, while coinsurance shares the cost of more expensive medical services after you’ve met your deductible.
When comparing health insurance plans, don’t focus only on premiums. Review the deductible, copays, coinsurance percentage, provider network, and out-of-pocket maximum to understand your total potential costs. Choosing the right balance can help you manage medical expenses while ensuring you have the coverage you need.
