What ICD-10 Codes are Used for Encephalopathy?
Encephalopathy is a term that means brain disease, damage, or malfunction. In modern usage, encephalopathy does not refer to a single disease but a syndrome of overall brain dysfunction. This syndrome can have many different organic and inorganic causes. Here are some of the commonly used ICD-10 codes for Encephalopathy:
- G93.40 - Encephalopathy, unspecified: This code is used when the type of Encephalopathy is not specified in the medical records. This falls under the "Other disorders of the nervous system."
- G93.49 - Other Encephalopathy: This code is used when the patient's condition doesn't match any specific types of Encephalopathy. It's used when the documentation supports the patient has Encephalopathy, but it differs from the types described in other categories.
- K76.82 - Hepatic Encephalopathy: Hepatic encephalopathy is a worsening of brain function that occurs when the liver can no longer remove toxic substances in the blood. This code took effect on October 1, 2022.
- G92 - Toxic Encephalopathy: This code is for Encephalopathy caused by exposure to harmful substances. It often results from exposure to drugs or toxins.
- G31.83 - Metabolic Encephalopathy: This code is used to classify Encephalopathy resulting from metabolic issues, such as electrolyte imbalances, organ failure, or endocrine dysfunctions.
- G31.2 - Degenerative Dementia, Not Elsewhere Classified: This code is used when the patient's dementia is due to brain damage or disease, not Alzheimer's or other specific degenerative diseases.
- F05 - Delirium Due to Known Physiological Condition: This code is used when delirium results from a known physiological condition, which could be any medical condition other than a mental disorder.
