Valid for Submission
G40.B19 is a billable diagnosis code used to specify a medical diagnosis of juvenile myoclonic epilepsy, intractable, without status epilepticus. The code G40.B19 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code G40.B19 might also be used to specify conditions or terms like juvenile myoclonic epilepsy, refractory idiopathic generalized epilepsy or refractory juvenile myoclonic epilepsy.
The code G40.B19 is linked to some Quality Measures as part of Medicare's Quality Payment Program (QPP). When this code is used as part of a patient's medical record the following Quality Measures might apply: Epilepsy: Counseling For Women Of Childbearing Potential With Epilepsy.
Index to Diseases and Injuries
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code G40.B19 are found in the index:
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Juvenile myoclonic epilepsy
- Refractory idiopathic generalized epilepsy
- Refractory juvenile myoclonic epilepsy
Convert G40.B19 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code G40.B19 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Quality Payment Program Measures
When code G40.B19 is part of the patient's diagnoses the following Quality Measures apply and affect reimbursement. The objective of Medicare's Quality Measures is to improve patient care by making it more: effective, safe, efficient, patient-centered and equitable.

Information for Patients
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.

Juvenile myoclonic epilepsy
Juvenile myoclonic epilepsy is a condition characterized by recurrent seizures (epilepsy). This condition begins in childhood or adolescence, usually between ages 12 and 18, and lasts into adulthood. The most common type of seizure in people with this condition is myoclonic seizures, which cause rapid, uncontrolled muscle jerks. People with this condition may also have generalized tonic-clonic seizures (also known as grand mal seizures), which cause muscle rigidity, convulsions, and loss of consciousness. Sometimes, affected individuals have absence seizures, which cause loss of consciousness for a short period that appears as a staring spell. Typically, people with juvenile myoclonic epilepsy develop the characteristic myoclonic seizures in adolescence, then develop generalized tonic-clonic seizures a few years later. Although seizures can happen at any time, they occur most commonly in the morning, shortly after awakening. Seizures can be triggered by a lack of sleep, extreme tiredness, stress, or alcohol consumption.
