What is coinsurance in health insurance?

Coinsurance is your share of costs after meeting your deductible. For example, in an 80/20 plan, your insurer pays 80% and you pay 20% of covered costs after the deductible is met.

How does the deductible affect reimbursement?

You must pay your full deductible first before insurance kicks in. After meeting the deductible, the insurer pays its share (e.g., 80%) of remaining covered costs, until you reach your out-of-pocket maximum.

What is the out-of-pocket maximum?

The out-of-pocket maximum is the most you'll pay in a plan year. After reaching it, your insurer covers 100% of covered services for the rest of the year. In 2024, the ACA cap is $9,450 for individuals.

How Health Insurance Reimbursement Works

In the US, most health plans have a deductible (what you pay first), then coinsurance (your percentage share after the deductible), then an out-of-pocket maximum (where your share caps out).

Step 1: Pay your remaining deductible from the bill
Step 2: Apply coinsurance to the rest (e.g., 20% of remaining)
Step 3: Insurance pays its share (e.g., 80%) of the rest

Once you hit your out-of-pocket maximum ($9,450 for individuals in 2024), insurance pays 100% for the remainder of the plan year. Keep track of your year-to-date spending to know where you stand.

Frequently Asked Questions

Does the deductible apply to all services?

Not always. Many plans cover preventive care at 100% before the deductible. Copays for primary care visits may also apply before meeting the deductible, depending on your plan.

What is the difference between copay and coinsurance?

A copay is a fixed dollar amount (e.g., $30 per visit). Coinsurance is a percentage of the cost (e.g., 20%). Plans may use both — check your Summary of Benefits and Coverage for details.
