2022 ICD-10-CM Code G40.0

Localization-related (focal) (partial) idiopathic epilepsy and epileptic syndromes with seizures of localized onset

Version 2021

Not Valid for Submission

ICD-10:G40.0
Short Description:Local-rel (focal) idio epilepsy w seizures of loc onset
Long Description:Localization-related (focal) (partial) idiopathic epilepsy and epileptic syndromes with seizures of localized onset

Code Classification

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

G40.0 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) idiopathic epilepsy and epileptic syndromes with seizures of localized onset. The code is not specific and is NOT valid for the year 2022 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 for Local-rel (focal) idio epilepsy w seizures of loc onset

Non-specific codes like G40.0 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 local-rel (focal) idio epilepsy w seizures of loc onset:

  • NON-BILLABLE CODE - G40.00 for Localization-related (focal) (partial) idiopathic epilepsy and epileptic syndromes with seizures of localized onset, not intractable
  • BILLABLE CODE - Use G40.001 for Localization-related (focal) (partial) idiopathic epilepsy and epileptic syndromes with seizures of localized onset, not intractable, with status epilepticus
  • BILLABLE CODE - Use G40.009 for Localization-related (focal) (partial) idiopathic epilepsy and epileptic syndromes with seizures of localized onset, not intractable, without status epilepticus
  • NON-BILLABLE CODE - G40.01 for Localization-related (focal) (partial) idiopathic epilepsy and epileptic syndromes with seizures of localized onset, intractable
  • BILLABLE CODE - Use G40.011 for Localization-related (focal) (partial) idiopathic epilepsy and epileptic syndromes with seizures of localized onset, intractable, with status epilepticus
  • BILLABLE CODE - Use G40.019 for Localization-related (focal) (partial) idiopathic epilepsy and epileptic syndromes with seizures of localized onset, intractable, without status epilepticus

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code G40.0:


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.

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Information for Patients


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.
