Where 208D00000X sits
- Group: Allopathic & Osteopathic Physicians — code 38 of 238 in the group
- Classification: General Practice 208D00000X
General Practice has no specializations, so 208D00000X is the only code for it. A provider may report more than one taxonomy code on an NPI but marks one as primary.
Medicare
CMS's taxonomy crosswalk links 208D00000X to Medicare specialty 01 (Physician/General Practice) and Medicare specialty 99 (Physician/Undefined Physician type). That specialty — not the taxonomy code itself — is what Medicare enrollment records and uses for payment. 9,388 practitioners are enrolled under it nationally.

Using 208D00000X
The code goes in the taxonomy field of the NPI application in NPPES, and on claims where a payer asks for it — box 24J (shaded) or 33b on the CMS-1500 with the ZZ qualifier, or the PRV segment of an 837 electronic claim. Payers match it against the taxonomy on the NPI record and, for Medicare, against the specialty on the enrollment, so all three should agree. To see which code a provider uses, search their NPI in the lookup.
