207X00000X Orthopaedic Surgery Physician

Definition

An orthopaedic surgeon is trained in the preservation, investigation and restoration of the form and function of the extremities, spine and associated structures by medical, surgical and physical means. An orthopaedic surgeon is involved with the care of patients whose musculoskeletal problems include congenital deformities, trauma, infections, tumors, metabolic disturbances of the musculoskeletal system, deformities, injuries and degenerative diseases of the spine, hands, feet, knee, hip, shoulder and elbow in children and adults. An orthopaedic surgeon is also concerned with primary and secondary muscular problems and the effects of central or peripheral nervous system lesions of the musculoskeletal system.

Where 207X00000X sits

• Group: Allopathic & Osteopathic Physicians — code 108 of 238 in the group
• Classification: Orthopaedic Surgery 207X00000X

This is the general code for Orthopaedic Surgery. 7 more specific codes sit beneath it; pick one of those when the provider's training or certification matches it, and this one otherwise. A provider may report more than one taxonomy code on an NPI but marks one as primary.

Medicare

CMS's taxonomy crosswalk links 207X00000X to Medicare specialty 02 (Physician/General Surgery) and Medicare specialty 20 (Physician/Orthopedic Surgery). That specialty — not the taxonomy code itself — is what Medicare enrollment records and uses for payment. 27,817 practitioners are enrolled under it nationally, and 24 other taxonomy codes map to the same specialty.

Other codes under the same Medicare specialty: 204E00000X Oral & Maxillofacial Surgery (D.M.D.); 204F00000X Transplant Surgery Physician; 207T00000X Neurological Surgery Physician; 207XP3100X Pediatric Orthopaedic Surgery Physician; 207XS0106X Orthopaedic Hand Surgery Physician; 207XS0114X Adult Reconstructive Orthopaedic Surgery Physician; 207XS0117X Orthopaedic Surgery of the Spine Physician; 207XX0004X Orthopaedic Foot and Ankle Surgery Physician; and 16 more.

Similar codes in other groups

If 207X00000X is not quite right, these codes in other groups share a word with it — often the same field practised by a different kind of provider:

• 1223S0112X Oral and Maxillofacial Surgery (Dentist) (Dental Providers)
• 163WS0121X Plastic Surgery Registered Nurse (Nursing Service Providers)
• 213ES0103X Foot & Ankle Surgery Podiatrist (Podiatric Medicine & Surgery Service Providers)

Using 207X00000X

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.
