Warnings:

1. This data set is too big to be opened in excel. Unzipped it’s over 4GB and has over 300 fields. Even with a database solution, it’s not an easy file to load or use.
2. To make the file more useful, I recommend also downloading the taxonomy code file. This will map the taxonomy codes to actual provider types and specialties. See link Below.
3. I created a consolidated version of the NPI registry that’s only approx. 40 fields. Let me know if you are interested in purchasing this version. Much more manageable and already has the Taxonomy information mapped into it. ([email protected])
