Code Classification

  • Diseases of the nervous system
    (G00–G99)
    • Other disorders of the nervous system
      (G89-G99)
      • Other disorders of brain
        (G93)

G93 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of other disorders of brain. 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 Other disorders of brain

Non-specific codes like G93 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 other disorders of brain:

  • Use G93.0 for Cerebral cysts - BILLABLE CODE

  • Use G93.1 for Anoxic brain damage, not elsewhere classified - BILLABLE CODE

  • Use G93.2 for Benign intracranial hypertension - BILLABLE CODE

  • G93.3 for Postviral and related fatigue syndromes - NON-BILLABLE CODE

  • Use G93.31 for Postviral fatigue syndrome - BILLABLE CODE

  • Use G93.32 for Myalgic encephalomyelitis/chronic fatigue syndrome - BILLABLE CODE

  • Use G93.39 for Other post infection and related fatigue syndromes - BILLABLE CODE

  • G93.4 for Other and unspecified encephalopathy - NON-BILLABLE CODE

  • Use G93.40 for Encephalopathy, unspecified - BILLABLE CODE

  • Use G93.41 for Metabolic encephalopathy - BILLABLE CODE

  • Use G93.42 for Megaloencephalic leukoencephalopathy with subcortical cysts - BILLABLE CODE

  • Use G93.43 for Leukoencephalopathy with calcifications and cysts - BILLABLE CODE

  • Use G93.44 for Adult-onset leukodystrophy with axonal spheroids - BILLABLE CODE

  • Use G93.49 for Other encephalopathy - BILLABLE CODE

  • Use G93.5 for Compression of brain - BILLABLE CODE

  • Use G93.6 for Cerebral edema - BILLABLE CODE

  • Use G93.7 for Reye's syndrome - BILLABLE CODE

  • G93.8 for Other specified disorders of brain - NON-BILLABLE CODE

  • Use G93.81 for Temporal sclerosis - BILLABLE CODE

  • Use G93.82 for Brain death - BILLABLE CODE

  • Use G93.89 for Other specified disorders of brain - BILLABLE CODE

Brain Diseases

Your brain is the control center of your body. It controls your thoughts, memory, speech, and movement. It regulates the function of many organs. It's part of your nervous system, which also includes your spinal cord and peripheral nerves. The nervous system sends signals between your brain and the rest of the body. Your nerves take in information from your senses and send it to the brain to be processed. Your brain and nerves also communicate to help you move and to control your body's functions.

When the brain is healthy, it works quickly and automatically. But when you have a brain disease, it may affect how well you can function and do your daily activities. Some common brain diseases include:

  • Brain tumors, which can press on nerves and affect brain function.
  • Degenerative nerve diseases, which can affect many of your body's activities, such as balance, movement, talking, breathing, and heart function. Types include Alzheimer's disease and Parkinson's disease.
  • Encephalitis (inflammation in the brain), which can lead to problems such as vision loss, weakness, and paralysis.
  • Genetic brain disorders, which are caused by changes in genes (also called variants or mutations). These disorders can affect the development and function of the brain.
  • Strokes, which can cause a loss of brain cells and can affect your ability to think clearly.
  • Traumatic brain injuries (TBIs), which can affect brain function. They may range from mild to severe. The effects of a TBI may be temporary or permanent.

The symptoms of brain diseases vary widely, depending on the specific problem. In some cases, damage is permanent. In other cases, treatments such as surgery, medicines, or therapies such as physical, occupational, and speech therapies, may cure the disease or improve the symptoms.
