Other encephalitis, myelitis and encephalomyelitis
ICD-10 G04.8 is a billable code used to indicate a diagnosis of other encephalitis, myelitis and encephalomyelitis.
G04.8 encompasses various forms of encephalitis, myelitis, and encephalomyelitis that do not fall under more specific categories. These conditions involve inflammation of the central nervous system (CNS) and can result from infectious agents, autoimmune responses, or other etiologies. Encephalitis refers to inflammation of the brain, which can lead to neurological deficits, seizures, and altered mental status. Myelitis involves inflammation of the spinal cord, potentially causing motor and sensory deficits. Encephalomyelitis combines both brain and spinal cord inflammation, often presenting with a spectrum of neurological symptoms. The clinical presentation can vary widely depending on the underlying cause, ranging from viral infections (such as herpes simplex virus or arboviruses) to post-infectious autoimmune reactions. Diagnosis typically involves clinical evaluation, imaging studies, and sometimes lumbar puncture for cerebrospinal fluid analysis. Treatment may include antiviral medications, corticosteroids, and supportive care, depending on the specific diagnosis and severity of symptoms.
Detailed neurological examination findings, imaging results, and laboratory tests.
Patients presenting with seizures, altered mental status, or focal neurological deficits.
Ensure clear documentation of the clinical course and response to treatment.
Identification of infectious agents, treatment protocols, and response to therapy.
Patients with suspected viral or atypical infections leading to CNS symptoms.
Document any travel history or exposure to infectious agents.
Used to obtain CSF for analysis in suspected cases of encephalitis.
Document indication for lumbar puncture and results of CSF analysis.
Neurology and Infectious Disease specialists should ensure thorough documentation of clinical findings.
Use G04.8 when the encephalitis or myelitis does not fit into a more specific category, such as viral or postinfectious encephalitis, and when the underlying cause is not clearly defined.
