TAXONOMY HELP
The Health Care Provider Taxonomy Code (HCPTC) set is an external non-medical data code set designed for use in classifying health care providers according to provider type or practitioner specialty in an electronic environment, specifically within the American National Standards Institute (ANSI) Accredited Standards Committee (ASC) health care claim transaction. The HCPTC list is a collection of unique alphanumeric codes, 10 characters in length, called taxonomy codes. The code set is structured into three distinct 'levels,' including provider type, classification, and area of specialization.
The taxonomy codes allow a single provider (individual, group or institution) to identify their areas of specialization. Providers may have one or more areas of specialization. When determining what value or values to associate with a provider, the user needs to review the requirements of the trading partner with which value(s) are being used.
To register an NPI with Medi-Cal, a provider is asked to enter the 10-digit taxonomy code(s) that they provided on the original NPI application to NPPES. If the provider gave a written taxonomy description on the original NPI application, then submit the taxonomy code(s) that were assigned by NPPES.
If a provider has more than one area of specialization, the taxonomy code for the area they specialize in the most is referred to as the 'Primary Provider Taxonomy Code'. When registering an NPI with Medi-Cal, there is allotted space to include additional pertinent taxonomy codes.
