RARC N4: Missing or Invalid Prior Payer EOB

What This Means

The Explanation of Benefits (EOB) from the prior insurance carrier is missing, incomplete, or invalid. This typically occurs when billing a secondary payer without attaching the primary payer's EOB. Obtain the complete EOB from the primary insurer showing what was paid or denied, and resubmit the claim with the correct documentation attached.
