How to read your Explanation of Benefits (EOB)
An EOB is a math worksheet, not a bill. Match it to the provider bill, pay the you-owe amount, and treat surprise-billing flags as reviews only.
An Explanation of Benefits (EOB) is a statement your insurer sends after processing a claim. It is not a bill — it shows what was billed, what the plan paid, and what you owe. Compare every EOB against the bill from the provider before paying. Pay the EOB you-owe (patient responsibility) amount, not the billed chargemaster sticker, unless your plan materials say otherwise.
The columns you'll see
- Amount billed — The provider's sticker price. Often inflated, especially for out-of-network care.
- Allowed amount (or 'plan allowed') — The maximum the plan considers reasonable. This is the number cost-sharing is calculated from.
- Plan discount — The difference between billed and allowed. For in-network providers, this is the negotiated discount you don't have to pay.
- Plan paid — What the insurer paid the provider.
- Your responsibility — Deductible, copay, coinsurance, and any non-covered amount you owe.
- Remark codes — Numbered codes explaining why a portion was denied, adjusted, or paid at a different rate.
How to verify your EOB
- Match the date and provider to your records
Check that the visit date and provider name match what you remember. Mismatches can signal billing errors or fraud.
- Confirm the procedure makes sense
Glance at the procedure description. If you went in for a strep test and see codes for a knee MRI, something is wrong.
- Check the network status
If you're sure the provider was in-network but the EOB applied out-of-network rates, call the insurer with the provider directory in hand.
- Add up your responsibility
Deductible + copay + coinsurance + non-covered = your responsibility. The math should add up exactly.
- Compare to the provider's bill
Wait for the provider's bill and check that what they're asking matches your responsibility column on the EOB. If not, call both — usually the provider is wrong. In BenAsk Documents, a Linked chip means the bill and EOB are already paired; Possible match lets you confirm or dismiss. Inbox can remind you when a linked bill is due soon.
How BenAsk uses billed vs typical rates
After you upload an EOB or bill, BenAsk compares the billed amount to public Transparency-in-Coverage (in-network) rates for the same procedure, then estimates your share from your selected medical plan: remaining deductible, copay vs coinsurance, and any patient-responsibility amount already listed. The claim or document summary can show a banner when the billed amount is in range, is mainly an insurer write-off, or may change what you pay. Inbox alerts are created only for that last case—not when public rates are missing. A surprise-billing (No Surprises Act) Inbox row is a review flag, not a legal conclusion that the Act applies.
FAQ
- Why is my EOB labeled 'This is not a bill'?
Because it's a record of how the insurer processed the claim, not a request for payment. Your actual bill comes from the provider. When both are in BenAsk, pay the EOB you-owe amount unless the provider statement matches that column.
- Why did BenAsk say this charge may cost me more?
The billed or allowed amount is higher than typical in-network rates, and given your remaining deductible and plan type, your estimated share would change. A high sticker price alone is often an insurer write-off and will not create this alert.
- What does remark code N362 / CO-45 / PR-1 mean?
Every code is explained in the legend on the EOB itself. If something doesn't make sense, call the customer service number on the EOB — they can interpret each code.
- How long should I keep EOBs?
At least one year, and longer for major procedures or anything you might appeal. For HSA-eligible expenses, keep them with your tax records.
- Does Draft message to my plan send the letter?
No. It opens Chat with an assist-only draft you copy and send yourself. BenAsk does not mail, fax, or email the carrier for you.
