ICD-10 Code G40.824 – Epileptic spasms, intractable, without status epilepticus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G40.824 – Epileptic spasms, intractable, without status epilepticus
What it is
This code identifies epileptic spasms that are not controlled with treatment and are not occurring as status epilepticus. Use it when documentation shows persistent spasms despite therapy.
Clinical signs
Clinical features vary; refer to documentation. Typical notes describe brief, sudden muscle contractions in clusters, often with developmental concerns or abnormal EEG findings.
When to use this code
Use G40.824 when the provider documents epileptic spasms as intractable, refractory, or poorly controlled. It also fits when the record clearly states the spasms are not status epilepticus. If the chart does not specify intractability, check documentation.
Do not use for
Do not use this code for epileptic spasms without documentation of intractability. It is also not correct when status epilepticus is documented instead.
Coding tip
Confirm both elements in the note: epileptic spasms and intractable status, plus the absence of status epilepticus.
