Reference NPI Information (as per NPPES NPI Record)

Field Name Field Value
NPI 1083674550
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 Y
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).
Provider Last Name (Legal Name) Chang
The last name of the provider (if an individual). If the provider is an individual, this is the legal name. This name must match the name on file with the Social Security Administration (SSA).
