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. Optometrists (OD) examine eyes, prescribe glasses and contact lenses and treat some eye conditions; what they may treat varies by state. Confirm each clinician's license with the state optometry board.

Registered specialty is not a license check. Confirm the optometrist's license with the state optometry board, or the ophthalmologist's with the state medical board and board certification with the American Board of Ophthalmology. Under the FTC's Eyeglass Rule you get a copy of your glasses prescription after the exam.
