Name and Address Segments (
N4) in X12 EDI
Here is a typical snippet of EDI representing a billing provider’s name and address.

An additional piece of provider-related data that can supplied on a claim is provider’s specialty, expressed using their taxonomy code. Providers can have multiple specialties so specifying the exact code used as part of the service may be sometimes mandated by insurance companies. The taxonomy code is provided using the
