Copays & Coinsurance Guide

Copays and Coinsurance, Decoded

Copays: flat and predictable

A copay is a fixed price for a service: $30 for a doctor visit, $60 for a specialist, $15 for a generic prescription. You pay it at the visit, and it usually does not depend on your deductible status.

Coinsurance: a percentage after the deductible

Coinsurance is your share of costs after meeting your deductible, commonly 20 percent for you and 80 percent for the plan. On a $10,000 procedure, that is $2,000 out of your pocket, until you reach your out-of-pocket maximum.

Why the out-of-pocket max is your true worst case

Add your deductible spending and coinsurance together and the plan stops charging you once you hit the annual maximum. When comparing plans, that number tells you your realistic bad-year cost.

Seeing Copays and Coinsurance in Action

The examples below are fictional and for illustration only. They do not represent any real plan, provider, or bill.

• Example 1 — Generic prescription refill: A $15 copay applies regardless of deductible status. You pay $15 at the pharmacy counter, full stop.
• Example 2 — Specialist visit after meeting the deductible: The visit's negotiated rate is $220. With 20% coinsurance, you pay $44 and the plan pays $176.
• Example 3 — Outpatient procedure before the deductible is met: The negotiated rate is $1,800 and $500 of deductible remains unmet. You pay the $500 toward the deductible, then 20% coinsurance applies to the remaining $1,300, adding $260. Total for this visit: $760.
