A three-segment NDC identifying an exact commercial package — the form that belongs on a claim.
0169-4132-12 is a package NDC: labeler, product, package. This is what the barcode encodes, what the wholesaler ships against and what the payer prices.
When a claim is denied for an invalid NDC, the most common cause is that a product NDC was submitted where a package NDC was required, or that the code was not padded to 11 digits.
