Check your taxonomy code in NPPES
A taxonomy code is a 10-character alphanumeric code that uniquely identifies your specialty at the claim level. Taxonomy codes are administrative codes that identify the type and area of specialization of your provider.
Please ensure that your taxonomy code in the National Plan and Provider Enumeration System (NPPES) database is correct so that you can safely prescribe controlled substances.
If the taxonomy code listed with the NPI is incorrect, your patients may be unable to fill controlled substance prescriptions at the pharmacy.
