Quick answer
When the patient responsibility on your EOB differs from the bill, compare the two documents line by line. The bill may include uncovered services, incorrect coding, or amounts that exceed what your plan approved.
Why the Amounts Differ
The patient responsibility on your EOB reflects what your plan determined you owe. The bill reflects what the provider wants to collect. Common reasons for the difference include uncovered services, incorrect codes, timing, or missing adjustments.
Verify Covered vs. Non-Covered Services
Check your EOB for any services listed as denied or non-covered. These are not included in the patient responsibility total, but the provider may bill you the full amount for them.
Check for In-Network Adjustments
If you went in-network, the provider agreed to accept the allowed amount as payment in full. The bill should reflect this contractual adjustment. If it does not, the provider is billing incorrectly.
Dispute the Difference
Contact the provider billing department with both your EOB and the bill. Explain that the patient responsibility on the EOB does not match the bill. Ask for an explanation of each line item.
What the research says
For in-network care, the EOB patient responsibility is the plan official determination of what you owe.
