Is an NPI proof of board certification?

No. An NPI is a free, lifetime identifier issued by CMS to anyone who bills Medicare or Medicaid. It does not confirm board certification, current licensure, hospital privileges, or training. Always verify those separately.

Can I tell from PlainDoctor whether a provider has been disciplined?

No. PlainDoctor only displays public CMS NPPES directory data and CMS nursing-home quality ratings. We do not display malpractice history, disciplinary actions, or sanctions. Use the relevant state board’s license-lookup tool for that information.

What does the NUCC taxonomy code mean?

NUCC (National Uniform Claim Committee) maintains the taxonomy of provider specialties used on CMS claims. Each provider self-selects a primary code at NPI enrollment, so a single code does not guarantee board certification, only the provider’s self-declared primary practice category.

Is this tool a substitute for medical advice?

No. The lookup tool helps you locate and verify a provider’s public credentials. It is not medical advice and does not endorse, rate, or rank any provider. Treatment decisions belong with you and your clinician.
