Individual vs Organization NPI explained

NPI-1 identifies an individual clinician or sole proprietor. NPI-2 identifies a group, facility, or organization. Both exist in the same public registry, but they answer different product questions.

If your UI always renders a person name, organization records will look broken. If your data model ignores entity type, billing and credentialing rules become harder to enforce.
