Specific Coding for Absence epileptic syndrome

Non-specific codes like G40.A require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for absence epileptic syndrome:

  • NON-BILLABLE CODE - G40.A0 for Absence epileptic syndrome, not intractable
  • BILLABLE CODE - Use G40.A01 for Absence epileptic syndrome, not intractable, with status epilepticus
  • BILLABLE CODE - Use G40.A09 for Absence epileptic syndrome, not intractable, without status epilepticus
  • NON-BILLABLE CODE - G40.A1 for Absence epileptic syndrome, intractable
  • BILLABLE CODE - Use G40.A11 for Absence epileptic syndrome, intractable, with status epilepticus
  • BILLABLE CODE - Use G40.A19 for Absence epileptic syndrome, intractable, without status epilepticus

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.
