What Pain Medicine covers
Pain Medicine is a primary medical specialty based on a distinct body of knowledge and a well-defined scope of clinical practice that is founded on science, research and education. It is concerned with the study of pain, the prevention of pain, and the evaluation, treatment, and rehabilitation of persons in pain. A comprehensive evaluation incorporates the physical, psychological, cognitive and socio-cultural contributions to pain. The treatment protocol may include pharmacological, invasive, behavioral, cognitive, rehabilitative and complementary strategies provided in a concurrent focused and patient specific manner. The pain medicine physician often serves the patient as a frontline physician regarding their pain, but also may serve as a consultant to other physicians, direct an interdisciplinary/multidisciplinary treatment team, conduct research, or advocate for the patient's pain care with public and private agencies. The Pain Medicine physician may work in variety of settings including office, clinic, hospital, university, or governmental/public agencies. NUCC Health Care Provider Taxonomy, code 208VP0000X

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 | 3 | 0 | 3 | 4 | 2 | 1 | 0 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 7 | 6 | 0 | 6 | 4 | 4 | 1 | 0 |
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.
