Acute flaccid myelitis
ICD-10 G04.82 is a billable code used to indicate a diagnosis of acute flaccid myelitis.
Acute flaccid myelitis (AFM) is a rare but serious neurological condition characterized by sudden onset of weakness in one or more limbs, often accompanied by neck stiffness, pain, and respiratory difficulties. AFM primarily affects children and is associated with viral infections, particularly enteroviruses, including enterovirus D68. The condition leads to inflammation of the spinal cord's gray matter, resulting in flaccid paralysis. Diagnosis is typically made through clinical evaluation, MRI imaging, and lumbar puncture to analyze cerebrospinal fluid (CSF). The clinical presentation may mimic other neurological disorders, making differential diagnosis crucial. AFM can lead to long-term disability, and while some patients may recover, others may experience persistent weakness or other complications. The exact etiology remains under investigation, with ongoing research into the role of viral infections and immune responses in the pathogenesis of AFM.
Detailed neurological examination findings, imaging results, and laboratory tests.
Diagnosis of AFM following a viral infection, evaluation of limb weakness, and management of respiratory complications.
Neurologists must document the onset of symptoms, progression, and any interventions undertaken.
History of recent viral infections, physical examination details, and developmental assessments.
Pediatric patients presenting with sudden limb weakness after a viral illness.
Pediatricians should emphasize the child's developmental history and any associated symptoms.
Used for follow-up visits after AFM diagnosis.
Detailed history, examination findings, and treatment plan.
Neurologists and pediatricians should document ongoing assessments and interventions.
Common symptoms include sudden weakness in limbs, neck stiffness, pain, and respiratory difficulties, often following a viral infection.
