EOB Says $0 but the Hospital Sent Me a Bill
An EOB showing zero patient responsibility means your plan covered the full allowed amount. If the hospital bills you anyway, the bill may be incorrect.

Quick answer
If your EOB shows $0 patient responsibility and the hospital still sends a bill, contact the provider billing department with your EOB. The bill may be a duplicate, a system error, or a charge for a service not covered by your plan.
Why This Happens
A bill arriving after a $0 EOB is usually the result of one of several issues.
- System delay - the provider billing system sent the statement before the EOB arrived.
- Duplicate billing - the provider submitted the claim twice and billed you for the second.
- Service not on the EOB - the bill includes a charge processed separately.
- Data entry error - the billing department entered the wrong amount.
Check for Additional Services
Pull out your EOB and compare every service listed to the hospital bill. If the bill includes a service not on your EOB, that charge may have been denied or processed under a separate claim.
Contact the Provider
Call the hospital billing department and reference your EOB claim number. Explain that your EOB shows $0 patient responsibility. Ask them to review the account and correct or void the bill.
What the research says
A $0 patient responsibility on your EOB means your plan covered the full allowed amount for covered services.
Frequently asked questions
Can the hospital bill me for something not on the EOB?
Yes, but only if the service was not covered. In that case, it would appear on a separate denial notice, not as a charge on your EOB.
Should I ignore the bill if my EOB says $0?
Do not ignore it - contact the provider to resolve the discrepancy. Ignoring a bill can lead to collection activity even if incorrect.
