This is an NPI-based check only. NPISignal does not publish name-based exclusion matches on a provider profile. A shared or similar name is a lead that requires human review, not an identification, and this page is not the place to make one. Run a name-based screening below to see potential matches with the reasons for each.

Taxonomy code 2083P0500XLegal Medicine
Allopathic & Osteopathic Physicians
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.
