What Legal Medicine covers
Legal Medicine is a special field of medicine that focuses on various aspects of medicine and law. Historically, the practice of legal medicine made contributions to medicine as a scientific instrument to solve criminal perplexities. Since World War II, the domain of legal medicine has broadened to include not only aspects of medical science to solve legal and criminal problems but aspects of law as it applies to medicine. Legal Medicine continues to grow as medicolegal issues like medical malpractice and liability, government regulation of health care, issues of tort reform, and moral and ethical complexities presented by technological advances become increasingly prominent. Many medical schools have implemented courses which supply medicolegal instruction for medical students, and many law schools now offer medicolegal courses. Also, dual degree programs in law and medicine have been created to assist physicians to bridge the gap between medicine and the law. NUCC Health Care Provider Taxonomy, code 209800000X

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 | 2 | 8 | 5 | 8 | 1 | 5 | 8 | 3 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 2 | 7 | 5 | 7 | 1 | 1 | 8 | 6 |
Sum = 63 · next multiple of 10 = 70 · check digit = 7 · actual last digit = 7
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.
