What Sports Medicine covers
A family medicine physician that is trained to be responsible for continuous care in the field of sports medicine, not only for the enhancement of health and fitness, but also for the prevention of injury and illness. A sports medicine physician must have knowledge and experience in the promotion of wellness and the prevention of injury. Knowledge about special areas of medicine such as exercise physiology, biomechanics, nutrition, psychology, physical rehabilitation, epidemiology, physical evaluation, injuries (treatment and prevention and referral practice) and the role of exercise in promoting a healthy lifestyle are essential to the practice of sports medicine. The sports medicine physician requires special education to provide the knowledge to improve the health care of the individual engaged in physical exercise (sports) whether as an individual or in team participation.

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 | 6 | 4 | 5 | 5 | 3 | 4 | 2 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 1 | 3 | 4 | 1 | 5 | 6 | 4 | 4 |
Sum = 54 · next multiple of 10 = 60 · 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.
