Copays, Coinsurance, and Deductibles Explained

Understanding Cost-Sharing

Patients share the cost of their medications through several mechanisms. A copay is a fixed dollar amount the patient pays at the pharmacy, such as $10 for a generic drug. Copay amounts vary by formulary tier, with generics having the lowest copays and specialty drugs having the highest.

Coinsurance is a percentage of the medication cost that the patient pays. For example, 20% coinsurance on a $100 medication means the patient pays $20. Coinsurance is more common for specialty and high-cost medications.

Deductibles and Out-of-Pocket Maximums

A deductible is the amount the patient must pay out of pocket before insurance begins to cover costs. If a plan has a $500 deductible, the patient pays the full cost of medications until they have spent $500 in a plan year.

The out-of-pocket maximum caps the total amount a patient pays in a year. Once reached, the insurance covers 100% of covered medications for the rest of the plan year.
