Encephalitis, myelitis and encephalomyelitis in diseases classified elsewhere
Chapter 6:Diseases of the nervous system
ICD-10 G05 is a billable code used to indicate a diagnosis of encephalitis, myelitis and encephalomyelitis in diseases classified elsewhere.
G05 encompasses encephalitis, myelitis, and encephalomyelitis that arise as complications of other diseases. These conditions involve inflammation of the brain (encephalitis), spinal cord (myelitis), or both (encephalomyelitis), often due to infectious agents such as viruses, bacteria, or parasites. The clinical presentation can vary widely, including symptoms such as fever, headache, seizures, altered mental status, and neurological deficits. Infections leading to these conditions may stem from systemic illnesses like viral infections (e.g., herpes simplex virus, West Nile virus), autoimmune disorders, or post-infectious processes. Accurate coding requires a thorough understanding of the underlying disease causing the encephalitis or myelitis, as well as the specific manifestations observed in the patient. This code is crucial for capturing the complexity of these conditions, which may require multidisciplinary management and can lead to significant morbidity.
Detailed neurological examination findings, imaging results, and laboratory tests.
Patients presenting with altered mental status, seizures, or focal neurological deficits.
Ensure clarity in distinguishing between infectious and autoimmune causes.
Identification of infectious agents through cultures, serologies, and imaging studies.
Patients with systemic infections presenting with neurological symptoms.
Document the timeline of infection and neurological symptoms for accurate coding.
Used to evaluate for signs of encephalitis or myelitis.
Document indications for the CT scan and findings.
Neurology specialists should ensure imaging correlates with clinical findings.
G05 should be used when encephalitis, myelitis, or encephalomyelitis is a complication of another disease, and the underlying condition is well-documented.
