What This Code Means
CO-178 is applied when submitted claim data does not provide enough information for the payer to determine coverage or payment. This is an administrative completeness issue rather than a coverage denial. The service may be eligible once sufficient information is provided. The code supports other adjustment or remark codes explaining the deficiency.
