Explanation of Benefits (EOB)
The payer’s statement explaining how a claim was processed — what was allowed, paid, adjusted, and left to the patient.
Talk to a billing specialistDefinition
An Explanation of Benefits (EOB) is the statement a health plan issues to explain how it processed a claim. It shows the billed amount, the allowed amount, what the plan paid, any contractual adjustments, and the portion that is the patient’s responsibility such as copay, coinsurance, or deductible.
An EOB is a statement, not a bill. The provider-facing, electronic equivalent used to post payments is the ERA (835); the EOB is typically the human-readable version, and the patient receives their own copy from the plan.
Why it matters for billing
The EOB (and its electronic ERA counterpart) is how a billing team reconciles what was expected against what was actually paid. Reading it correctly is what surfaces underpayments, unexpected adjustments, and denials that need to be worked.
