What taxonomy code 111NI0900X means
111NI0900X is the National Uniform Claim Committee code for Chiropractor, Internist, in the grouping Chiropractic Providers. 342 NPPES records list it as their primary taxonomy (file of Aug 9, 2026).
The chiropractic internist may serve as a primary care physician or may see patients referred from other providers for evaluation and co-management. Evaluation is focused on the early detection of functional, nutritional, and pathological disorders. A chiropractic internist utilizes the diagnostic instruments necessary for proper examination. In cases where laboratory examination is necessary, a chiropractic internist utilizes a recognized reference laboratory facility. A chiropractic internist may manage his or her own cases or may refer to another specialist when prudent to do so. The chiropractic internist utilizes documented natural therapies, therapeutic lifestyle changes, patient education and other resources to promote patient health and avoidance of disease.
