1 Rev /07 Claims Resolution Matrix Institutional This Claims Resolution Matrix is to be used as a reference tool to troubleshoot institutional claims that have been submitted electronically (i.e., submitted via 87I transaction) and rejected. Refer to the Code Definitions document for detailed information about category, entity, and claim status codes. Note: The Claim Status Codes you receive on your rejection may not be in the same order as they appear below in the primary, secondary, and tertiary status columns. Please be sure to search all columns for the applicable Claim Status Code. For example, on your rejection, you may have received Claim Status Codes 8 and 56; however, on the 77CA you may see these Claim Status Codes in the order of 56 and 8.
