What is taxonomy code?
A taxonomy code is a ten-character identifier that identifies your categorization and area of expertise. When applying for a National Provider Identifier, often known as an NPI, you’ll need this code.

You must first enroll in the Medicare programme in order to become a Medicare provider and file Medicare claims.
