From our advocates: "We've seen Illinois patients successfully overturn Firdapse denials by emphasizing that it's the only FDA-approved treatment for LEMS and including detailed EMG reports showing the characteristic incremental response. The key is demonstrating that the diagnosis meets established neurological criteria and that no alternative treatments are appropriate."
