0.000What This Code Means
Juvenile myoclonic epilepsy that does not respond adequately to medication, but the patient is not currently experiencing prolonged or repeated seizure activity.
Coding Tips
- •Confirm intractability is documented (seizures not controlled despite medication trials)
- •Verify absence of status epilepticus at the time of encounter or documentation period
Clinical Significance
Intractable juvenile myoclonic epilepsy without status epilepticus indicates ongoing drug-resistant seizures in a patient with JME who is not in acute crisis. Since JME typically responds to appropriate medication, intractability should prompt review of the medication regimen for inappropriate agents and assessment for medication adherence, particularly in the adolescent population.
Documentation Requirements
- ✓Confirmed JME diagnosis
- ✓Documentation of intractability with list of failed medications
- ✓Absence of status epilepticus
- ✓Verification that appropriate JME medications were tried (valproate, levetiracetam)
- ✓Assessment of medication adherence
- ✓Current seizure frequency and impact on daily life
