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. Midwives are licensed or regulated by the state, and the rules for certified professional midwives (CPM) and licensed midwives differ from state to state. Confirm the license with the state board before you sign a care agreement.
