EXPLANATION OF PAYMENT (EOP)

An EOP will be sent to each provider once the claim has been processed. If multiple claims are processed under the same provider, a bulk payment will be made. Claim information will be listed alphabetically below the check. These are usually issued once a week.

When posting the EOP, each patient’s identifying information appears in the shaded box above the service line information. If a service line is rejected, a two or three character code appears next to the ineligible dollar amount. Explanation codes for rejected claims appear at the end of the remittance advice.

If a claim does not appear on an EOB within 60 days of submission, the claim should be statused prior to resubmittal.

The following is a list of the most common Explanation Codes that may appear on a provider’s EOP. For codes not appearing on this list, please refer to the end of the EOP for a detailed description.
