G36.1

Acute and subacute hemorrhagic leukoencephalitis [Hurst]

Clinical Classification Guidelines

Medical Intelligence & Overview

Acute and subacute hemorrhagic leukoencephalitis, also known as Hurst's disease, is a rare and severe form of brain inflammation. It involves rapid-onset inflammation and bleeding in the white matter of the brain, which can lead to serious neurological complications. Recognizing this condition early is crucial for managing symptoms and preventing long-term damage.

Causes & Symptoms

Clinical Causes: Infections, such as viral or bacterial illnesses Autoimmune reactions where the immune system attacks brain tissue Pre-existing conditions that trigger abnormal immune responses Occasionally, reactions to certain medications or vaccines Unknown factors in some cases

Key Symptoms: Sudden neurological problems including weakness or paralysis Altered mental status such as confusion or reduced consciousness Severe headache Fever and chills Visual disturbances or changes in vision Loss of coordination or balance Seizures in some instances Sensory disturbances like numbness or tingling

Diagnostic & Treatment

Diagnosis Path: Diagnosing hemorrhagic leukoencephalitis typically involves a combination of methods. Healthcare providers may perform neurological examinations and neuroimaging tests such as MRI or CT scans to visualize brain inflammation and bleeding. Lumbar puncture (spinal tap) may be conducted to analyze cerebrospinal fluid for signs of inflammation. Blood tests can also help identify underlying infections or immune responses. Due to the rapid progression of symptoms, early diagnosis is essential for effective management.

Treatment Protocols: Treatment strategies focus on reducing brain inflammation, managing symptoms, and preventing further neurological damage. These often include high-dose corticosteroids to suppress immune activity and inflammation. In some cases, immunosuppressive medications may be used. Supportive care in a hospital setting can involve medications to control seizures, manage swelling, and address neurological deficits. Because the condition progresses quickly, intensive monitoring and supportive interventions are usually necessary. Rehabilitation therapy might be needed if neurological impairments persist.

Reimbursement claims with a date of service on or after October 1, 2015 require the use of ICD-10-CM codes.
