Code Classification

  • Diseases of the nervous system
    (G00–G99)
    • Episodic and paroxysmal disorders
      (G40-G47)
      • Epilepsy and recurrent seizures
        (G40)

G40.20 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of localization-related (focal) (partial) symptomatic epilepsy and epileptic syndromes with complex partial seizures, not intractable. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Local-rel symptc epi w complex partial seiz, not ntrct

Non-specific codes like G40.20 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for local-rel symptc epi w complex partial seiz, not ntrct:

  • Use G40.201 for Localization-related (focal) (partial) symptomatic epilepsy and epileptic syndromes with complex partial seizures, not intractable, with status epilepticus - BILLABLE CODE

  • Use G40.209 for Localization-related (focal) (partial) symptomatic epilepsy and epileptic syndromes with complex partial seizures, not intractable, without status epilepticus - BILLABLE CODE

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Localization-related (focal) (partial) symptomatic epilepsy and epileptic syndromes with complex partial seizures without intractability

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.
