  • A one-sentence request and your office callback number

Questions to resolve

  • Does this team handle this plan and state?
  • Which department owns the next step?
  • What reference number should the office keep?

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