What Neurology covers
Chiropractic Neurology is defined as the field of functional neurology that engages the internal - and external environment of the individual in a structured and targeted approach to affect positive changes in the nervous system and consequently the physiology and behavior of an individual. Chiropractic Neurologists are board-certified specialists in non-drug, non-surgical care for those with neurologically based health problems. There are many conditions people suffer from that are in this broad category: learning and attention disorders, headaches, vertigo, pain syndromes, developmental disorders, nerve injury, spinal cord injury, head injury or stroke, movement disorders, and many other conditions.

The taxonomy records how the provider classifies their own practice. It does not confirm which conditions they currently treat, whether they are accepting new patients, or which insurance they take — call the office for that.
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 | 7 | 6 | 0 | 2 | 8 | 7 | 1 | 2 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 7 | 3 | 0 | 4 | 8 | 5 | 1 | 4 |
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.
