ICD-10 Code G40.822 – Epileptic spasms, not intractable, without status epilepticus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G40.822 – Epileptic spasms, not intractable, without status epilepticus
What it is
This code identifies epileptic spasms that are not described as intractable and are not occurring as status epilepticus. Use it when the record documents this specific seizure type and does not indicate persistent, difficult-to-control seizures.
Clinical signs
Clinical features vary; refer to documentation. Epileptic spasms are brief, sudden flexion or extension movements, often occurring in clusters and sometimes associated with altered awareness or developmental concerns.
When to use this code
Use this code when the provider specifically documents epileptic spasms and states they are not intractable. It also applies when the note confirms there is no status epilepticus. If the chart uses only “seizures” or “spasm” without epilepsy detail, check documentation.
Do not use for
Do not use this code for intractable epileptic spasms or for episodes documented as status epilepticus. Avoid it when the seizure type is different or the record does not clearly support epileptic spasms.
Coding tip
Confirm both qualifiers, “not intractable” and “without status epilepticus,” before assigning G40.822.
