Toxic encephalopathy
Chapter 6:Diseases of the nervous system
ICD-10 G92 is a billable code used to indicate a diagnosis of toxic encephalopathy.
Toxic encephalopathy is a neurological condition resulting from exposure to toxic substances, which can lead to a range of cognitive, behavioral, and physical impairments. The condition is characterized by diffuse brain dysfunction, often manifesting as altered mental status, seizures, and motor disturbances. Common etiologies include exposure to heavy metals, solvents, and certain medications. Patients may present with symptoms such as confusion, memory loss, headaches, and autonomic dysfunction, which can include changes in heart rate and blood pressure. In severe cases, toxic encephalopathy can lead to hydrocephalus due to impaired cerebrospinal fluid absorption or production. Diagnosis typically involves a thorough clinical history, neurological examination, and may include imaging studies to assess for structural changes in the brain. Management focuses on removing the source of toxicity, supportive care, and rehabilitation to address cognitive and motor deficits. The prognosis varies depending on the duration and severity of exposure, as well as the promptness of treatment.
Detailed neurological examination findings, history of toxin exposure, and any imaging results.
Patients presenting with altered mental status following known exposure to neurotoxic substances.
Ensure that the documentation clearly links symptoms to the toxic exposure for accurate coding.
Comprehensive toxicological screening results and detailed patient history regarding exposure.
Patients with acute or chronic symptoms following exposure to chemicals or drugs.
Documentation must include specific toxins and their potential effects on the nervous system.
Used for follow-up visits for patients diagnosed with toxic encephalopathy.
Documentation must include history, examination findings, and treatment plan.
Neurologists may require additional neuropsychological assessments.
Common causes include exposure to heavy metals, solvents, pesticides, and certain medications that can have neurotoxic effects.
Diagnosis is based on clinical history of exposure to toxins, neurological examination, and exclusion of other causes of encephalopathy.
Prognosis varies widely depending on the duration and severity of exposure, as well as the timeliness of treatment. Some patients may recover fully, while others may have lasting cognitive deficits.
