What Sports Physician covers
A sports chiropractor is uniquely trained to provide care and treatment of injuries or illness resulting from sports and physical fitness activities. Doctors of Chiropractic with the Diplomate American Chiropractic Board of Sports Physicians (DACBSP) or the Certified Chiropractic Sports Physician (CCSP), sport specialty certifications from the American Chiropractic Board of Sports Physicians, have advanced training in the assessment, management and rehabilitation of sports related injuries. Extremity care, rehabilitation and soft tissue procedures are common skills utilized by these doctors. The specialty training covers a broad spectrum from the pediatric athlete to professional and Olympic athletes, and everything in between, using a variety of techniques and modalities.

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 | 1 | 2 | 4 | 0 | 4 | 1 | 6 | 1 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 1 | 4 | 4 | 0 | 4 | 2 | 6 | 2 |
Sum = 49 · next multiple of 10 = 50 · check digit = 1 · actual last digit = 1
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.
