What Orthopedic covers
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.

Full NPPES record
An NPI-1 identifies a single person. It stays with the clinician for life, even if they move practice or change state, which is why the address on file can lag behind where they actually work today.

Number check
How the check works, step by step
Every NPI carries a Luhn check digit — the same scheme used on credit cards. CMS prefixes the number with 80840 before computing it, which marks it as a US health identifier.
| Digit | 8 | 0 | 8 | 4 | 0 | 1 | 0 | 8 | 3 | 7 | 3 | 4 | 0 | 3 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 0 | 7 | 3 | 5 | 3 | 8 | 0 | 6 |
Sum = 58 · next multiple of 10 = 60 · check digit = 2 · actual last digit = 2
A valid check digit only means the number is well-formed. It does not mean the provider is licensed, active, or in good standing — those are separate questions answered by the sections above.
