What is the difference between Type 1 and Type 2 NPI?
A Type 1 NPI is assigned to individual health care providers, including physicians, dentists, and all sole proprietors. A Type 2 NPI is assigned to health care providers who are organizations, including physician groups, hospitals, skilled nursing homes, and the corporation formed when an individual incorporates him/herself. Organizations must determine if they have “subparts” that need to be uniquely identified in HIPAA standard transactions with their own NPIs.
