Lennox-Gastaut syndrome, not intractable, w stat epi

This code identifies a severe form of childhood epilepsy characterized by multiple seizure types, intellectual disability, and a specific EEG pattern (slow spike-and-wave). Crucially, the seizures in this instance are currently responsive to treatment (not intractable) but are presenting as status epilepticus, a prolonged seizure or series of seizures without full recovery of consciousness between them.

Apply this code when documentation clearly indicates a diagnosis of Lennox-Gastaut syndrome where the seizures are currently controlled with medication or other interventions, but the patient is experiencing an episode of status epilepticus. Supporting documentation should specify the LGS diagnosis, the "not intractable" nature of the epilepsy, and the presence of status epilepticus.

• Ensure documentation explicitly states "not intractable" for Lennox-Gastaut syndrome; otherwise, a different subcategory may be more appropriate.
• Verify the presence of status epilepticus; if absent, codes for LGS without status epilepticus should be considered.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter, unless another condition is clearly the principal diagnosis.
