N517: Descriptor not independently confirmed against an authoritative source
Secondary billing resources associate N517 with authorization or notification issues, but no verified official X12 descriptor text could be confirmed for this entry during research. Treat any description of this code as unverified until confirmed against the current X12 RARC list or a payer's own remittance guide.
