What are Subparts?

The NPI Final rule refers to separate locations, licensure, or specialty of an organizational health care provider as a "subpart". The subparts often operate independently of each other and usually conduct their own billing.

  • By subparting, each location will receive its own separate NPI.
  • Medi-Cal Dental recommends qualifying providers obtain separate NPIs for each of their subparts.
  • Failure to subpart may result in claims processing and payment delays.

Provider Identification Number (PIN)

If a provider chooses not to subpart and obtains one (1) NPI for multiple Medi-Cal Dental provider numbers, the PIN designated for the "01" office must be used in all transactions where the PIN is required, regardless of which service office provides services.
