An EOB is NOT a bill — it’s a statement from your insurer showing what they paid, what they didn’t, and what you may owe. Compare it against the actual bill to catch errors.
An Explanation of Benefits often looks alarming but it is not a bill — it’s your insurer explaining how they processed a claim: the billed amount, what insurance covered, any adjustments, and your estimated responsibility. The actual bill comes separately from the provider. The EOB is a powerful tool: compare it line-by-line against the provider’s bill. If the provider is billing you more than the EOB says you owe, or for services the EOB shows as covered, that’s an error worth disputing before you pay.
It’s your insurer’s record of how they processed the claim, so you can verify coverage and catch errors before the provider’s actual bill arrives.
That’s a red flag — the provider may be balance-billing or making an error. Dispute it in writing, citing the EOB’s stated patient responsibility.
