When a patient uses a doctor's Nation Provider Identifier, or NPI, number, he finds basic information such as personal information, NPI information, details on the doctor's practice and other licensing information, according to the National Plan & Provider Enumeration System. The system removes any Social Security numbers provided by doctors.
The personal information found by using a doctor's NPI number includes the doctor's full name, gender and whether he is the sole proprietor of the practice he works at, says the National Plan & Provider Enumeration System. The provided NPI information is the doctor's NPI number, entity type, the date of enumeration and the date of the last update for the NPI number. It also includes dates for replacement NPI numbers, deactivation of the number and reactivation of the number if applicable.
Other information available with a doctor's NPI number is the location of the doctor's practice and the mailing address. This includes the phone number and fax number for the practice, explains the National Plan & Provider Enumeration System. The information provided in the doctor's taxonomy includes the type of selected taxonomy, the doctor's license number and the state that issued the medical license. If the doctor did not provide the taxonomy information, the doctor's medical license number and issuing state appear in the Other Provider Identifier section.
