Querying & Reporting Codes
It is important that all reports and queries you submit are properly completed and contain codes that accurately represent, for example, the type of practitioner, the reportable action, or the purpose of a query. Your accurate reporting and querying result in better information for protecting the public and in fulfilling the mission of the NPDB.
Codes
Based upon your suggestions, and changes that occur in the health care field, the NPDB periodically updates the code lists. Use the following lists to create accurate submissions and to interpret your NPDB responses.
