Non-Formulary Drugs

  2. Download and print the form for your prescription drug.
  3. Give the form to your provider to complete.
  4. Send the form to Express Scripts. Follow the instructions on the completed form. You don’t need to submit multiple forms.  Your medical necessity approval will apply to both the retail network pharmacy and home delivery.
