Have ready in your secure workspace

  • PBM name and the pharmacy identifiers on the card
  • Drug, formulation and prescription information
  • Prescriber details and previous review reference

Questions to resolve

  • Is this processed under the medical or pharmacy benefit?
  • What is the correct review and submission channel?
  • Is there a separate specialty pharmacy or appeal team?

This is a general administrative checklist, not payer policy or advice about a particular patient. Confirm the current plan instructions.
