Myasthenia Gravis

Affects approximately 14–20 per 100,000 people in the U.S.·7 treatments

Myasthenia gravis is an autoimmune neuromuscular disorder that causes weakness in the skeletal muscles. It occurs when antibodies block or destroy acetylcholine receptors at the junction between the nerve and muscle. Symptoms include drooping eyelids, double vision, difficulty swallowing, and muscle fatigue that worsens with activity.

Search Trials

Insurers typically require trial and failure of pyridostigmine (Mestinon) and at least one immunosuppressant (mycophenolate, azathioprine, or prednisone) before approving biologics like Vyvgart or complement inhibitors like Soliris/Ultomiris. IVIG is often restricted to acute exacerbations or pre-surgical optimization rather than ongoing maintenance therapy.

Must fail pyridostigmine and immunosuppressants before biologic therapy

Very Common

AChR or MuSK antibody testing not documented

Common

IVIG limited to acute exacerbation — not approved for maintenance

Common

Vyvgart or complement inhibitor denied without prior biologic failure

Occasional

Insufficient documentation of disease severity (MG-ADL or QMG scores)

Occasional

  1. 1.Document AChR or MuSK antibody status — antibody-positive status strengthens the case
  2. 2.Include MG-ADL and/or QMG scores showing disease severity
  3. 3.Document all prior immunosuppressant trials with dates, doses, and reasons for failure
  4. 4.For complement inhibitor requests, document generalized MG with inadequate response to standard therapy
  5. 5.Cite MGFA classification and note any myasthenic crisis history
