G40.901 - Epilepsy, unspecified, not intractable, with status epilepticus
| ICD-10: | G40.901 |
| Short Description: | Epilepsy, unsp, not intractable, with status epilepticus |
| Long Description: | Epilepsy, unspecified, not intractable, with status epilepticus |
| Status: | Valid for Submission |
| Version: | ICD-10-CM 2023 |
| Code Classification: |
G40.901 is a billable ICD-10 code used to specify a medical diagnosis of epilepsy, unspecified, not intractable, with status epilepticus. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
Unspecified diagnosis codes like G40.901 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
Approximate Synonyms
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Idiopathic partial status epilepticus
- Postoperative status epilepticus
- Status epilepticus
- Status migrainosus
Clinical Information
- Alcohol Withdrawal Seizures-. a condition where seizures occur in association with ethanol abuse (alcoholism) without other identifiable causes. seizures usually occur within the first 6-48 hours after the cessation of alcohol intake, but may occur during periods of alcohol intoxication. single generalized tonic-clonic motor seizures are the most common subtype, however, status epilepticus may occur. (adams et al., principles of neurology, 6th ed, p1174)
- Status Epilepticus-. a prolonged seizure or seizures repeated frequently enough to prevent recovery between episodes occurring over a period of 20-30 minutes. the most common subtype is generalized tonic-clonic status epilepticus, a potentially fatal condition associated with neuronal injury and respiratory and metabolic dysfunction. nonconvulsive forms include petit mal status and complex partial status, which may manifest as behavioral disturbances. simple partial status epilepticus consists of persistent motor, sensory, or autonomic seizures that do not impair cognition (see also epilepsia partialis continua). subclinical status epilepticus generally refers to seizures occurring in an unresponsive or comatose individual in the absence of overt signs of seizure activity. (from n engl j med 1998 apr 2;338(14):970-6; neurologia 1997 dec;12 suppl 6:25-30)
- Epilepsia Partialis Continua-. a variant of epilepsy characterized by continuous focal jerking of a body part over a period of hours, days, or even years without spreading to other body regions. contractions may be aggravated by movement and are reduced, but not abolished during sleep. electroencephalography demonstrates epileptiform (spike and wave) discharges over the hemisphere opposite to the affected limb in most instances. the repetitive movements may originate from the cerebral cortex or from subcortical structures (e.g., brain stem; basal ganglia). this condition is associated with russian spring and summer encephalitis (see encephalitis, tick borne); rasmussen syndrome (see encephalitis); multiple sclerosis; diabetes mellitus; brain neoplasms; and cerebrovascular disorders. (from brain, 1996 april;119(pt2):393-407; epilepsia 1993;34;suppl 1:s29-s36; and adams et al., principles of neurology, 6th ed, p319)
- Juvenile Myoclonic Epilepsy, Intractable, without Status Epilepticus-. intractable juvenile myoclonic epilepsy which is not associated with an acute, prolonged epileptic crisis.
- Non-Convulsive Status Epilepticus-. status epilepticus without prominent motor symptoms, the duration of which is at least ten minutes.
- Status Epilepticus-. a life-threatening situation in which the brain is in a continuous state of seizure.

Patient Education
Epilepsy
Epilepsy is a brain disorder that causes people to have recurring seizures. The seizures happen when clusters of nerve cells, or neurons, in the brain send out the wrong signals. People may have strange sensations and emotions or behave strangely. They may have violent muscle spasms or lose consciousness.
Epilepsy has many possible causes, including illness, brain injury, and abnormal brain development. In many cases, the cause is unknown.
Doctors use brain scans and other tests to diagnose epilepsy. It is important to start treatment right away. There is no cure for epilepsy, but medicines can control seizures for most people. When medicines are not working well, surgery or implanted devices such as vagus nerve stimulators may help. Special diets can help some children with epilepsy.
