Prior Authorization for Prescription Drugs

Before submitting a Prescription Drug Prior Authorization Request (PAR) Form, search HPSM’s formulary for the drug you want to prescribe. Make sure you search the formulary for the member’s specific health plan.

  • If the drug you searched is in the formulary, you do not need to submit the authorization form.
  • If the drug you searched is not in the formulary or has the initials NF, PA, QL or ST next to it, then complete the Prescription Drug PAR Form and fax it to HPSM at 650-829-2045.
