  • Repetitive nerve stimulation (RNS) showing >60% CMAP amplitude increase after brief exercise
  • Cancer screening (chest CT, then PET-CT if negative)

4. Document Treatment History (You + Doctor - Week 4)

Gather records showing:

  • Failed or inadequate response to pyridostigmine
  • Contraindications to immunosuppression (if applicable)
  • Functional impact documentation (muscle weakness scores, daily living limitations)

5. Submit Prior Authorization (Doctor's Office - Week 5)

Your physician submits the PA request with complete documentation package via Blue Cross Blue Shield Illinois provider portal or fax.

6. Follow Up on Timeline (You - Week 7)

Standard PA decisions take 15 business days. If urgent, request expedited review (24-hour decision required by Illinois law).

7. Appeal if Denied (You + Doctor - Within 30 Days)

Illinois provides strong appeal rights with external review available if internal appeals fail.

Prior Treatment Records

Compile documentation of previous treatments:

  • Pyridostigmine trials: doses tried, duration, response, and side effects
  • Immunosuppressive therapy: if attempted, include specific medications and outcomes

Tip: Bring a one-page summary of your treatment history with dates, medications, doses, and outcomes. This saves appointment time and ensures accuracy.
