Is an EOB a medical bill?

No. An Explanation of Benefits explains how insurance processed a claim. A provider bill asks for payment. Compare both before paying.

What should I compare first?

Start with the same date of service, provider, claim, allowed amount, adjustment, payment, denial reason, and patient responsibility.

What if the bill and EOB do not match?

Ask the provider whether insurance payments and adjustments were applied, ask for the itemized bill, and ask the insurer to explain the EOB or denial reason in writing.

EOB vs medical bill: match the same date before you pay

An EOB is not a bill. It is the insurance company's explanation of how a claim was processed. The provider bill is the payment request. If those two documents do not line up, slow down and compare the details first.

Denials and missing info

Bill: The provider may still bill while insurance is waiting on records or review.

Ask the provider billing office

I am comparing this bill against my EOB before paying. Please confirm whether all insurance payments and adjustments have been applied, whether this balance matches the EOB patient responsibility, and whether you can send the itemized bill with codes, quantities, and dates of service.

Ask the insurer

I am trying to understand the EOB for this claim. Please explain the allowed amount, adjustment, payment, denial or remark code, patient responsibility, appeal deadline, and whether the provider needs to submit additional documentation or a corrected claim.
