Solomon Copilot™What is an EOB?
The document marked "This is not a bill" is one of your most useful tools, if you know how to read it against the bill that follows.
Not a bill, but a map
An Explanation of Benefits (EOB) is the statement your insurer sends after a claim. It shows what the provider charged, what the insurer allowed, what the insurer paid, and what you may owe. It is not itself a request for payment.
How to use it
Set the EOB next to the bill from the provider. The amount the provider bills you should reconcile with the patient-responsibility figure on the EOB. When they don't match, you have a question worth asking, and often an error worth disputing.
A provider billing you more than the EOB's patient-responsibility amount is a frequent and disputable discrepancy, sometimes a prohibited balance bill.
Key fields to compare
- Amount billed vs. the charge on your bill.
- Allowed amount: the negotiated rate.
- Plan paid: what insurance covered.
- Patient responsibility: what you should actually owe.
Stop guessing. See your bill, line by line.
Solomon scans every charge against current benchmarks, flags the errors and overcharges, and writes the dispute letter they will answer.
Analyze My Bill →Common questions
Is an EOB a bill?
No. It's an explanation from your insurer of how a claim was processed. The bill comes from the provider. Compare the two, discrepancies are where errors hide.
What if my bill is higher than the EOB says I owe?
That's a red flag. The provider's bill generally shouldn't exceed the patient-responsibility amount on the EOB. Dispute the difference in writing, and check whether it's a prohibited balance bill.
