111NX0800X Orthopedic Chiropractor

Definition

Chiropractic Orthopedics/Neuromusculoskeletal Medicine is defined as that branch of chiropractic medicine that includes the continued acquisition of knowledge relative to both normal functions and diseases of the human body as they relate to the bones, joints, capsules, discs, muscles, ligaments, tendons, their complete neurological and vascular components, referred organ systems and contiguous tissues. This also includes the development and perfection of skills relative to health maintenance when such exists and when not, the investigations, historical review, physical detection, correlative diagnosis development and complete management of any disorder within the bounds defined herein. Also necessary is the delivery of the combined knowledge and skill on a primary basis to patients who both need and desire this service to the eventual outcome of remissions, whenever resolution is not readily achievable. In addition the certified chiropractic orthopedist/neuromusculoskeletal medicine specialist provides consultation services at the request of other qualified doctors seeking assistance in the care of their patients. The chiropractic orthopedist/neuromusculoskeletal medicine specialist may also engage in the teaching and or research of subjects and materials relevant to pursuing the quest for knowledge in the ever changing field of the orthopedic specialty.

Where 111NX0800X sits

• Group: Chiropractic Providers — code 7 of 12 in the group
• Classification: Chiropractor 111N00000X
• Specialization: Orthopedic 111NX0800X

Choose 111NX0800X over the general Chiropractor code (111N00000X) when the provider's training or certification is specifically in orthopedic; 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

CMS's taxonomy crosswalk links 111NX0800X to Medicare specialty 35 (Chiropractic). That specialty — not the taxonomy code itself — is what Medicare enrollment records and uses for payment. 45,873 practitioners are enrolled under it nationally, and 11 other taxonomy codes map to the same specialty.

Other codes under the same Medicare specialty: 111N00000X Chiropractor; 111NI0013X Independent Medical Examiner Chiropractor; 111NI0900X Internist Chiropractor; 111NN0400X Neurology Chiropractor; 111NN1001X Nutrition Chiropractor; 111NP0017X Pediatric Chiropractor; 111NR0200X Radiology Chiropractor; 111NR0400X Rehabilitation Chiropractor; and 3 more.

Similar codes in other groups

If 111NX0800X 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:

• 163WX0800X Orthopedic Registered Nurse (Nursing Service Providers)
• 2251X0800X Orthopedic Physical Therapist (Respiratory, Developmental, Rehabilitative and Restorative Service Providers)
• 246ZX2200X Orthopedic Assistant (Technologists, Technicians & Other Technical Service Providers)

Using 111NX0800X

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.
