New rules effective October 1, 2023

Prior authorization (PA) is a condition of payment for many services. It is a process initiated by the physician to verify medical necessity of a treatment before it is given to the patient.

  • The ordering/prescribing physician is responsible for determining which codes require PA.
  • Non-participating providers and facilities require authorization for all services except where indicated.
