I got a medical bill but no Explanation of Benefits. Should I pay it?

The bill is in your hand. Your plan has not sent you anything about it.

Without the Explanation of Benefits there is no way to know what your plan agreed to pay, what the provider agreed to write off, or what is genuinely yours. The bill on its own is one side of a negotiation you cannot see.

What the EOB adds that the bill does not have

• The allowed amount — the contracted rate, which is usually far below the list price on the bill
• What the plan paid
• The contractual adjustment — the write-off, which is often the largest number on the page
• Your actual share, broken into deductible, copay and coinsurance
• Any denial codes, and whether they assign the cost to you or to the provider

A bill can show a balance that is correct, or a balance that ignores every one of those. It looks the same either way.

What to do

Get the EOB before paying. Your insurer's website will have it under Claims once the claim is processed, often before the paper copy arrives.

If it is not there, the claim has not been processed, and the useful question is whether it was submitted at all:

Please confirm whether this claim was submitted to my plan and what the claim number is.

Then ask your plan for the Explanation of Benefits before paying.

Timing is not sinister

A bill that predates adjudication is common and usually just a billing cycle running on its own schedule. Compare the statement date on the bill with the processed date on the EOB when it arrives — if the bill is older, it was describing a moment before your plan had decided anything, and a corrected statement often follows without you doing anything.

You are allowed to wait

Asking a question is not a refusal to pay. There is no general rule that stops a bill under query going to collections, so ask for the account to be held:

Please place this account on hold, including any referral to collections, while the Explanation of Benefits is obtained.

Get the name of the person you spoke to and the date. Some protections are narrower but real: a nonprofit hospital generally has to wait at least 120 days after its first bill before extraordinary collection actions, and a collection agency must pause once you dispute a debt in writing.
