What Is an Explanation of Benefits — and What Do You Do With It?
By Cura Editorial Team ·
An Explanation of Benefits is not a bill. It is a summary from your insurance company that arrives after you receive medical care. It shows what your provider charged, what your insurance covered, and what you may owe — but it does not ask for payment. Your actual bill will come separately from your provider. If your EOB is confusing, Cura Well Plan can explain any line in plain language and tell you what to ask.
What every EOB contains
Every EOB contains the same basic information organized into columns.
- Date of service — when you received the care.
- Provider — who provided the care.
- Amount billed — what your provider charged the insurance company.
- Plan discount or adjustment — the amount written off because of your provider's contract with your insurer.
- Amount paid by insurance — what your insurance actually paid.
- Your responsibility — what you may owe, which becomes your bill.
Why the billed amount and the paid amount are so different
When a provider bills $500 for a service, your insurance company typically pays far less — sometimes $150 or $200. This is because of contracted rates negotiated between your insurer and the provider. The difference is written off. You only owe your portion of the contracted rate, not the original billed amount.
What to do when your EOB arrives
Check that the date of service and the provider match your actual visit. Look at the patient responsibility column — this is what your bill should show. When your provider's bill arrives, compare it to the EOB line by line. If the amounts do not match, call the provider's billing department first.

Frequently asked questions
What is an Explanation of Benefits?
An Explanation of Benefits is a summary your insurance company sends after you receive medical care. It shows what was charged, what insurance covered, and what you may owe.
Is an EOB a bill?
No. An EOB is not a bill and does not ask for payment. Your provider will send a separate bill, which should match the EOB.
Why is the amount billed so much higher than what insurance paid?
Insurers pay contracted rates negotiated with providers, which are often far below the billed amount. The difference is written off, and you only owe your share of the contracted rate.
What does the patient responsibility column mean?
It is the amount your insurance company says you owe after processing the claim, such as a deductible, copay, or coinsurance. Your provider's bill should show the same amount.
What should I do when I receive an EOB?
Check that the date of service and provider match your visit, and note the patient responsibility amount. When the bill arrives, compare it line by line and call the provider's billing department if anything differs.
