There will always be providers who do not have an NPI and will need to report non-NPI identifiers on their claim forms. The qualifiers will indicate the non-NPI number being reported.

NUCC INSTRUCTIONSEnter in the shaded area of 24I the qualifier identifying if the number is a non-NPI. The Other ID# of the rendering provider should be reported in 24J in the shaded area.

The NUCC defines the following qualifiers used in 5010A1:
  1. 0B State License Number
  2. 1G Provider UPIN Number
  3. G2 Provider Commercial Number
  4. LU Location Number
  5. ZZ Provider Taxonomy (The qualifier in the 5010A1 for Provider Taxonomy is PXC, but ZZ will remain the qualifier for the 1500 Claim Form.)
The above list contains both provider identifiers, as well as the provider taxonomy code. The provider identifiers are assigned to the provider either by a specific payer or by a third party in order to uniquely identify the provider. The taxonomy code is designated by the provider in order to identify his/her provider grouping, classification, or area of specialization. Both, provider identifiers and provider taxonomy may be used in this field.

In the case where a substitute provider (locum tenens) was used, enter that provider’s information here. Report the Identification Number in Items 24I and 24J only when different from data recorded in items 33a and 33b.
