From the Barnestorm main menu, click on Codes > Other Basic Codes > Doctors.
Click on the Print Codes button. This will generate a list of all doctors and facilities entered under Other Basic Codes > Doctors. You will see a column labeled NPI. If that row is blank for a doctor or facility, then an NPI has not been entered. You may open that doctor or facility, enter an NPI, and click the Save button.
