Looking for the name, address and phone number of your child's doctor when your ex leaves it as "Dr. Smith" (like there aren't 100s of those in your area)? Try narrowing down your search with the National Plan and Provider Enumeration System's searchable database. This is also an excellent database for the correct contact information for subpoenas and medical records requests.
The NPI Registry enables you to search for a provider's NPPES information. All information produced by the NPI Registry is provided in accordance with the NPPES Data Dissemination Notice. Information in the NPI Registry is updated daily. You may run simple queries to retrieve this read-only data. For example, users may search for a provider by the NPI or Legal Business Name. There is no charge to use the NPI Registry.
