Learn About You Costs and Coverage
Coinsurance and Copays
- Understanding Costs: You may hear the terms "coinsurance" and "copay" while enrolled in a Blue Cross MedicareRx plan. Coinsurance is a percentage of the bill you pay. Copays are a set amount you pay at the time of service.
Quick Facts About Claims and More
- Claims Filing: Your provider and pharmacist will usually file any claims for prescriptions you received. Once the claim is filed, you will get a statement called the Explanation of Benefits (EOB) from us. How often you receive it depends on how often you get care or fill your prescriptions.
- What is an EOB? The EOB is a statement, not a bill. It simply details what you have paid and indicates the level of benefits you've used.
- How to use an EOB: Review these to be sure they are correct. If you think there are errors on your EOB statement, or you think you are the victim of fraud, please call customer service.
