Every question you have about EOBs, answered

Need-to-know info about this important document

Between renewal letters, new ID cards, preventive health reminders and more, health insurance comes with a lot of paperwork. There's one document in particular that we send soon after you receive any medical services. It's called your Explanation of Benefits — EOB for short. EOBs can be particularly useful when it comes to understanding your benefits — like how much your provider charged for a service, how much your insurance company contributed or paid, and how much you ultimately owe.

Got questions about your EOB? Let's dive in.

What is an EOB?

Information in your explanation of benefits (EOB)

An EOB is as simple as its name: it's a written notice explaining how your benefits were applied to medical services you received. Your EOB will outline things like your provider's name, how much your provider charged for a particular service, money saved by getting care inside your plan's network, how much your insurance paid and how much you owe. It's important to remember that an EOB is not a bill. You'll typically pay the amount you owe directly to your provider.

Why did you send me an EOB?

EOBs not only provide detailed information on how your benefits apply to various medical services, but they can also help you understand your total cost of care and spot potential errors before you pay any medical bills.

What should I do if I see a mistake?

Mistakes happen to everyone. Maybe your provider's office incorrectly coded a certain service, resulting in an overcharge. Or, they forgot to note you paid your copay — and sent you a duplicate bill. If you notice something on your EOB is incorrect, start with your provider's office. If you need additional help, contact your insurance company.

How long should I keep my EOB?

Generally, you should hang on to your EOB until you can match it up with a bill from your provider's office, which may take anywhere from several weeks to a few months. (Your EOB should arrive much sooner than the bill, since insurance companies typically send them in regular batches once claims have been processed.)

You may also want to file your EOBs by date of service for year-end tax documentation or to help you understand your out-of-pocket costs for budgeting purposes. The good news? You no longer need a filing cabinet to keep all those EOBs handy: myWellmark® will store them Opens New Window for you securely online.
