We are from a Neurology group, and Iam seeking counsel on how to use a Taxonomy code that does not map into the physician primary specialty.

For paper UB04 institutional claims, the taxonomy code should be placed in box 81 and should be submitted with the “B3”qualifier.
  • For paper CMS-1500 professional claims, the taxonomy code should be identified with the qualifier “ZZ” in the shaded portion of box 24i. The taxonomy code should be placed in the shaded portion of box 24j for the rendering level and in box 33b preceded with the “ZZ” qualifier for the billing level.  

If a health care provider might need to report more than one Healthcare Provider Taxonomy Code or code description in order to adequately describe the type/classification/specialization.  Therefore, a health care provider may select more than one Healthcare Provider Taxonomy Code or code description when applying for an NPI, but must indicate one of them as the primary
