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 individual clinician. 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. Certified nurse-midwives hold a graduate degree from an ACME-accredited program and are certified by the American Midwifery Certification Board (AMCB); the state licenses them, usually through the board of nursing. Confirm the license with the state and the certification with AMCB.
