Where 156FC0801X sits
- Group: Eye and Vision Services Providers — code 10 of 17 in the group
- Classification: Technician/Technologist 156F00000X
- Specialization: Contact Lens Fitter 156FC0801X
Choose 156FC0801X over the general Technician/Technologist code (156F00000X) when the provider's training or certification is specifically in contact lens fitter; 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
156FC0801X 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 156FC0801X
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.
