GBS (Guillain-Barré Syndrome)
Guillain-Barré syndrome is a rare but serious autoimmune disorder where the immune system attacks the peripheral nerves, causing rapid-onset muscle weakness that can progress to paralysis. GBS is a medical emergency — treatment with IVIG or plasma exchange must begin promptly to reduce the severity and duration of the illness. Most patients recover, but recovery can take months to years.

Search TrialsIVIG (2g/kg over 2–5 days) or plasma exchange are the two evidence-based treatments for GBS. They are equivalent in efficacy. No step therapy should be required — this is an acute neurological emergency. Treatment should begin within 2 weeks of symptom onset for maximum benefit.
IVIG denied if symptoms are mild or patient is still ambulatory
Very Common
Diagnosis documentation insufficient (CSF analysis, nerve conduction studies not submitted)
Common
Treatment requested after the acute window (>2–4 weeks from onset)
Common
Second course of IVIG denied for relapsing or refractory GBS
Occasional
Outpatient IVIG denied — insurer requires inpatient administration only
Occasional
- 1.Emphasize urgency — GBS is a neurological emergency requiring immediate treatment
- 2.Document progressive weakness, inability to ambulate, or respiratory compromise
- 3.Include nerve conduction studies and CSF analysis (albuminocytologic dissociation)
- 4.If treatment is denied as 'not medically necessary,' request expedited review citing risk of respiratory failure
- 5.Cite AAN evidence-based guidelines supporting IVIG for moderate-to-severe GBS
