Training does not include those skills and knowledge necessary to direct a clinical laboratory.

Where 207SG0207X sits
- Group: Allopathic & Osteopathic Physicians — code 78 of 238 in the group
- Classification: Medical Genetics
- Specialization: Medical Biochemical Genetics 207SG0207X
Choose 207SG0207X over the general Medical Genetics code when the provider's training or certification is specifically in medical biochemical genetics; the general code covers the classification as a whole. A provider may report more than one taxonomy code on an NPI but marks one as primary.
Medicare
207SG0207X has no entry in the CMS Medicare Provider and Supplier Taxonomy Crosswalk. That usually means Medicare does not enroll this kind of provider under its own specialty — the provider can still hold an NPI and use this code on claims to other payers.

Using 207SG0207X
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.
