Quick Answer
An Explanation of Benefits (EOB) is a statement from your insurer showing how a claim was processed. It is not a bill. It usually shows the billed amount, the allowed amount, what your plan paid, and the patient-responsibility amount. Compare the patient-responsibility figure with your provider bill before paying anything, and ask your insurer to explain any code or figure that is unclear.

What is an Explanation of Benefits (EOB)?
An EOB is a statement your insurer sends after it processes a claim. Medicare.gov describes it as a notice showing how much a provider billed, the amount the plan will pay, and how much you may have to pay the provider. The same general idea applies across most health plans, though the exact layout varies by insurer.
An EOB is not a bill and is not a request for payment. It is a record of how the claim was processed that you can use to check against the bill your provider sends.
What this means for you
Do not pay an amount just because it appears on an EOB. Wait for the actual bill from your provider, then compare the two.

What do common EOB terms mean?
TermWhat it usually meansWhat to check
Billed amount
The amount the provider charged for the service.
Compare it with the itemized bill from the provider.
Allowed amount
The amount your plan agrees to recognize for the service, which may be lower than the billed amount.
This is usually the starting point for what your plan pays and what you may owe.
Plan discount or adjustment
A reduction between the billed amount and the allowed amount, often based on a provider's network agreement.
Ask your insurer what the adjustment reflects if it is unclear.
Amount your plan paid
What your insurer paid toward the allowed amount.
Compare this to the insurance payment shown on your bill.
Deductible
The amount you pay before your plan starts covering costs.
Check whether this claim was applied toward your deductible.
Copay
A fixed amount you pay for certain services.
Confirm it matches your plan's copay structure for that type of visit.
Coinsurance
A percentage of the allowed amount you pay after the deductible.
Compare the percentage shown with your plan documents.
Patient responsibility
What the EOB says you may owe after the plan's payment and any adjustments.
Compare this figure directly against the balance on your provider bill.

How do I read my EOB step by step?
- 1Find the claim number, date of service, and provider name.
- 2Locate the billed amount and the allowed amount.
- 3Check what your plan paid toward the allowed amount.
- 4Look for the deductible, copay, or coinsurance applied to this claim.
- 5Find the patient-responsibility amount.
- 6Check the claim status and any remark codes for denials or adjustments.
- 7Compare the patient-responsibility amount to your provider bill.
CMS publishes a sample EOB walkthrough that labels each of these sections on an example statement, which may help if your own EOB is laid out differently.
What if the bill and EOB don't match?
A mismatch does not automatically mean either document is wrong. The bill may have been sent before the claim finished processing, a later adjustment may have occurred, or the two documents may cover different dates or services.
Ask both the insurer and the provider's billing office to explain the difference before you pay.
What if my EOB shows a claim as denied?
A denial shown on an EOB means the plan did not pay that claim as submitted. It does not always mean the decision is final. Ask your insurer for the specific denial reason and whether the claim can be appealed or reprocessed.
What questions should I ask?
- Can you explain the difference between the billed amount and the allowed amount for this claim?
- How was my deductible, copay, or coinsurance applied to this claim?
- Why does the patient-responsibility amount on this EOB differ from my bill, if it does?
- What does this remark or claim status code mean?
- Was this provider processed as in-network or out-of-network for this claim?
What mistakes should I avoid?
Watch out for these common mistakes
- Treating the EOB as a bill and paying it directly
- Only looking at the patient-responsibility total without checking the underlying figures
- Not comparing the EOB to the provider's bill before paying
- Assuming a claim marked as denied on the EOB is final
- Not asking what a remark or claim status code means
- Confusing the billed amount with what you actually owe

Frequently asked questions
Is an Explanation of Benefits (EOB) a bill?
No. An EOB explains how your insurer processed a claim. It is not a request for payment. Your provider's bill is the document that asks you to pay.
Why don't the numbers on my EOB and bill match?
Differences can happen if the bill was sent before the claim finished processing, if a later adjustment occurred, or if the two documents cover different dates or services. Ask both the insurer and the billing office to explain any difference before paying.
What does it mean if my EOB shows a claim as denied?
A denial on an EOB means the plan did not pay for that claim as submitted. It does not always mean the decision is final. Ask your insurer for the specific denial reason and whether you can appeal.
What is the difference between the billed amount and the allowed amount?
The billed amount is what the provider charged. The allowed amount is what your plan recognizes for that service, which is often lower. Your plan's payment and your share are usually based on the allowed amount, not the billed amount.
What if I never received an EOB for a visit?
Check your insurer's member portal first, since EOBs are often available there even if a paper or email copy didn't arrive. If it's not there either, call your insurer and ask them to confirm whether the claim was processed and resend the EOB.
Should I keep my EOBs?
Yes, at least until the related bill is fully resolved, and longer if you're tracking deductible or out-of-pocket progress for the year. They're useful evidence if a bill or a later dispute needs comparing against what your insurer actually processed.
Can PapaShield tell me if my EOB is correct?
No. PapaShield does not verify claims processing or confirm whether an EOB is correct. It can help you organize the figures and questions to ask your insurer and provider.
