What Occupational Health covers
Occupational Health is that specialty within the chiropractic profession that deals with the prevention and management of work related injuries. It also considers and assists clients with State and Federal Compliance assistance. Occupational Health goes much farther than simply treating injured workers however. This may mean working with clients to promote optimum safety and ergonomic principles, interacting with the injured worker to promote safety and prevent future injuries, assisting a company with accident investigation to identify root cause, redesigning a workstation to eliminate hazards, working with safety teams, providing training programs etc. The list of potential services that the specialist can interact with a client company or patient is lengthy and varied involving both in office services as well as on site services.

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 | 6 | 3 | 6 | 9 | 3 | 7 | 9 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 0 | 3 | 3 | 3 | 9 | 6 | 7 | 9 |
Sum = 66 · next multiple of 10 = 70 · check digit = 4 · actual last digit = 4
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.
