As a provider, do I need to know my taxonomy code?

Yes, if you want to become a Medicare provider.

To become a Medicare provider and file Medicare claims, you must first enroll in the Medicare program. To enroll, you must have an NPI. And to get an NPI, your application will need to include the taxonomy code that reflects your classification and specialization.

Note: Applications for NPIs are processed through the National Plan & Provider Enumeration System, or NPPES.

Where do I find my taxonomy code?

To find the taxonomy code that most closely describes your provider type, classification, or specialization, use the National Uniform Claim Committee (NUCC) code set list. 
Note: You may select more than one code or code description when applying for an NPI, but you must indicate one of them as the primary code.
