We can advise here that Joseph Smith's NPI number is part of his personal ID and cannot be given without authorisation.
NPI stands for National Provider Identifier. It's a unique 10-digit identification number issued to healthcare providers by the Centers for Medicare & Medicaid Services (CMS) in the United States. The NPI number serves as a standardized identification for healthcare providers, including both individuals (such as doctors, nurses, therapists) and organizations (hospitals, clinics, group practices).
The NPI number helps in standardizing healthcare provider identification across the healthcare system. It does not carry any information about the provider's credentials, qualifications, or specialty.
