what is a taxonomy code

A taxonomy code is a unique 10-character code that designates a healthcare providers classification and specialization. It is used by healthcare providers to self-identify their specialty based on which taxonomy code best matches their specialty. The Health Care Provider Taxonomy code set is a collection of unique alphanumeric codes, ten characters in length, structured into three levels: provider type, classification, and area of specialization. Providers must select a taxonomy code when completing their application for a National Provider Identifier (NPI) . The NPI is a unique identification number for covered healthcare providers, required by HIPAA, and used in standard transactions throughout the healthcare industry. Taxonomy codes serve as a secondary identifier to ensure that a provider is accurately recognized in HIPAA standard transactions. They are also required for Medicaid claims for BlueSalud/BlueSCI. It is important that providers select the taxonomy code that most closely resembles their specialty to ensure correct payment of claims.
