Deductible, copay, coinsurance: what will I pay?
Four terms help explain a health plan’s costs. Use your Summary of Benefits and Coverage to check how they apply to each service.
Quick answer
Your premium keeps coverage in place. Your deductible, copays, and coinsurance are costs for using covered care. The in-network out-of-pocket limit caps certain covered costs; it is not a limit on every health-related expense.
Four terms, side by side
| Term | What it means | What to check |
|---|---|---|
| Deductible | An amount you pay for services subject to the deductible before the plan starts sharing those costs. | Some services have different rules or a separate deductible. |
| Copay | A set dollar amount for a covered service, such as a $30 office visit. | The visit may involve separate labs or procedures; the copay is not necessarily the entire bill. |
| Coinsurance | Your percentage of the allowed amount for covered care. | Check whether the deductible applies first. |
| Out-of-pocket limit | The plan’s cap on qualifying covered in-network cost sharing for the year. | Premiums, noncovered services, and many out-of-network costs are outside this limit. |
Follow the costs through a year
Assume covered in-network care, a $2,000 deductible, $30 primary-care copay that bypasses the deductible, 20% coinsurance after the deductible, and a $6,000 out-of-pocket limit. All these payments count toward the example’s out-of-pocket limit.
| Care | Your payment | Progress |
|---|---|---|
| Office visit | $30 copay | $0 toward deductible; $30 toward out-of-pocket limit. |
| MRI: $1,400 allowed | $1,400 | $1,400 deductible met; $1,430 toward out-of-pocket limit. |
| Surgery: $10,000 allowed | $600 remaining deductible + 20% × $9,400 = $2,480 | Deductible met; total qualifying payments $3,910. |
| After these services | $6,000 − $3,910 = $2,090 remaining to the limit | Assumes no other qualifying payments or adjustments. |
Use the allowed amount, not the provider’s original charge, when checking the coinsurance math. Your actual plan and claim processing determine the result.
Check the family rules and reset date
A family plan may have individual and family deductibles. Ask whether one person can meet an individual deductible before the whole family reaches its amount, and how individual out-of-pocket protections work. Read the reset date in your plan; not every plan year starts January 1.
Your next step
- Find the SBC and look up the specific service you expect to use.
- Check the provider network, authorization requirements, and any separate facility or lab charges.
- After care, compare the latest EOB with the bill and payments already made.
