What Does "Allowed Amount" Mean on My EOB?

What "Allowed Amount" Means

An EOB (explanation of benefits) is not a bill. It's a report from your insurance company about what happened to a claim your provider sent in. The allowed amount is what your insurance plan agreed to pay for a service, based on its contract with that provider. It is usually lower than the amount the provider first charged.

The difference between the original charge and the allowed amount is called an adjustment (sometimes labeled "write-off" or "contractual adjustment"). If the provider is in-network, that difference is usually written off — you should not owe it.

The Other Words on the Same Page

• CPT/procedure code — a number that identifies the exact service billed. Your EOB or bill should also have a plain description next to it. Use that description — not the code alone — to know what happened.
• Deductible — the amount you pay before your plan starts sharing costs.
• Copay — a fixed amount you pay for a visit or service.
• Coinsurance — the percentage of the allowed amount you pay after your deductible is met.
• Adjustment — the part of the original charge your insurer's contract removes.

When the Numbers Don't Add Up

The math on an EOB should work: charge, minus adjustment, minus what insurance paid, equals what you owe (patient responsibility). If those lines on your EOB or the bill you got don't add up to the amount you're being asked to pay, don't pay yet. Ask the biller for an itemized, corrected bill first.

If your EOB says you owe nothing, but a bill from the provider is asking you for money, that gap is worth a specific question to the provider's billing office: which one is current, the EOB or the bill?

If You're Insured and the Bill Involves Emergency or Out-of-Network Care

A federal protection called the No Surprises Act guards most insured patients against balance billing for emergency care and some out-of-network ancillary care. If your EOB or bill looks like this situation, call your insurer first, using the number on your insurance card, before you pay anything.
