Field Name Field Value
NPI 1770711947
10-position all-numeric identification number assigned by the NPS to uniquely identify a health care provider.
Entity Type Individual
Code describing the type of health care provider that is being assigned an NPI. Codes are:
  • 1 = (Person): individual human being who furnishes health care;
  • 2 = (Non-person): entity other than an individual human being that furnishes health care (for example, hospital, SNF, hospital subunit, pharmacy, or HMO).
Is Sole Proprietor N
Indicate whether provider is a sole proprietor.
  • A sole proprietor is the sole (the only) owner of a business that is not incorporated; that unincorporated business is a sole proprietorship.
  • In a sole proprietorship, the sole proprietor owns all of the assets of the business and is solely liable for all of the debts of the business.
  • There is no difference between a sole proprietorship and a sole proprietor; they are legally a single entity: an individual.
  • In terms of NPI assignment, a sole proprietor is an Entity type 1 (Individual) and is eligible for only one NPI (the sole proprietorship business is not eligible for its own NPI).
  • As an individual, a sole proprietorship cannot be a subpart and cannot have subparts. (See NPI Final Rule for information about subparts.)
  • A sole proprietorship may or may not have employees.
  • Often, the IRS assigns an EIN to a sole proprietorship in order to protect the sole proprietor's SSN from disclosure in claims or on W-2s. NPPES does not capture a sole proprietorship's EIN.
  • Many types of health care providers could be sole proprietorships (for example, group practices, pharmacies, home health agencies).
