Definition
An Orthopaedic Assistant is a person who has been trained to work as a physician extender in both clinical and surgical environments. An Orthopaedic Assistant assists with aspects of patient care as determined by the supervising surgeon including, but not limited to, obtaining patient history, assisting with examinations, injections, recording of office notes, and application/adjustment/removal of splints, casts, and other immobilization devices. Acting as a surgical first assistant for orthopaedic surgery cases includes providing aid in exposure, hemostasis, positioning of the patient, suturing and closure of body planes and skin, application of wound dressings or immobilization devices, and other technical functions that will help the surgeon carry out a safe operation with optimal results for the patient. An Orthopaedic Assistant may be licensed, registered, or certified depending on the state in which the individual practices.

Choose 246ZX2200X over the general Specialist/Technologist, Other code (246Z00000X) when the provider's training or certification is specifically in orthopedic assistant; 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
246ZX2200X 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.

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.
