    • Where appropriate, use the RPA taxonomy code (243U00000X) found in category 24.
  4. Be sure to record your username and password.(Note that the taxonomy code is for CBRPA RPA only. Do not use the RRA designation as this will be considered a misrepresentation of identity and will carry a serious financial penalty).

    Please note: The Health Care Provider Taxonomy Code (HCPTC) was granted only to RPAs credentialed by CBRPA, as the certification agency. In addition, the CBRPA scope of practice has been recognized as defining the field or parameters of practice. Other non-RPA (CBRPA) individuals attempting to use the HCPTC code will be subject to the same measures levied for fraudulent actions. The fines for an individual are $250,000 and possibly five (5) years in jail for providing fraudulent information on the NPI application.
