The prescriber key code is offered as an alternative option to accessing tasks in the ASPN Pharmacies website. The code provides up to 10 days of access to a single Prior Authorization (PA) or Rx Clarification (RXC) task. This code is included in fax and email notifications sent to the prescriber. ASPN Pharmacies can reissue a code, if needed. Click here to contact us. Be sure to include the expired prescriber key code. To gain further information on these tasks, an ASPN Pharmacies account must be created by clicking here.
