What Sports Medicine covers
A physician who specializes in Sports Medicine is responsible for continuous care related to the enhancement of health and fitness as well as the prevention of injury and illness. The specialist possesses knowledge and experience in the promotion of wellness and the prevention of injury from many areas of medicine such as exercise physiology, biomechanics, nutrition, psychology, physical rehabilitation, epidemiology, physical evaluation and injuries. It is the goal of a Sports Medicine specialist to improve the healthcare of the individual engaged in physical exercise. NUCC Health Care Provider Taxonomy, code 2081S0010X
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 | 6 | 7 | 9 | 8 | 9 | 0 | 6 | 3 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 6 | 5 | 9 | 7 | 9 | 0 | 6 | 6 |
Sum = 74 · next multiple of 10 = 80 · check digit = 6 · actual last digit = 6
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.
