Bill vs EOB
My EOB and Bill Do Not Agree
When your EOB and bill disagree, the EOB represents your plan official determination of what you owe.
Updated August 16, 2026 · 6 min read
Quick answer
When your EOB and bill do not agree, the EOB takes precedence as your insurer official record. The provider bill should match the EOB patient responsibility. If it does not, dispute the bill with documentation.
Which Document Is Authoritative
Your EOB is the official record from your insurer of how a claim was processed. The provider bill is a request for payment. If the two conflict, the EOB determines your legal obligation for in-network covered services.
What To Do First
Do not pay the bill until you have verified it against the EOB. Pull up both documents and compare every line. If the bill exceeds the EOB patient responsibility, contact the provider.
If the Provider Insists the Bill Is Correct
Ask the provider to provide written documentation supporting the higher amount. If they cannot, file a complaint with your state insurance commissioner. Keep copies of all correspondence.
Frequently asked questions
Can a provider send me to collections for an amount different from my EOB?
If the amount exceeds the EOB patient responsibility for in-network care, you have grounds to dispute.
What if both the EOB and the bill seem wrong?
Contact your insurer to verify the claim was processed correctly. If the EOB itself contains an error, your insurer must reprocess the claim.
