A copay is a set dollar amount that you will pay each time you receive a service. For example, paying $30 or $50 each time you see your doctor for an office visit. For FIC’s PPO plans, if a copay applies to a specific service, no deductible or coinsurance will also be required for that service. Coinsurance is a percentage that you will pay for certain services. You pay a portion of the insurance company’s negotiated price – not whatever the doctor might initially charge.
