What these registry facts mean

The NPI (National Provider Identifier) is the federal ID every HIPAA-covered provider uses to bill insurance. This NPI belongs to an organization, so it may cover several clinicians at this location. The specialty is the taxonomy the provider chose when registering; NPPES does not check it. A license number here is what the provider entered — confirm it with the state board before you rely on it. A registered specialty is not board certification. To check board certification, use the American Board of Dermatology's verification tool (or the American Osteopathic Board of Dermatology for DOs), and confirm the medical license with the state board.
