AHA Coding Clinic® for ICD-10-CM and ICD-10-PCS - 2021 Issue 4; ICD-10-CM New/Revised Codes
Acute Flaccid Myelitis
A new code (G04.82) was created to identify acute flaccid myelitis (AFM). Although rare, AFM is a serious neurologic condition that affects the gray matter of the spinal cord and causes the muscles and reflexes of the body to weaken. Neurologic symptoms may be preceded by a febrile respiratory illness and sometimes pain in the extremities. The most common signs and symptoms may include facial drooping/weakness, trouble moving the eyes, drooping eyelids, trouble swallowing or slurred speech. More severe symptoms involve complete paralysis, the inability to breathe, and respiratory failure, which can result in the need for long-term...

Article Overview
This article covers acute flaccid myelitis from a medical coding perspective, with emphasis on its clinical features, typical presentation, and the addition of a diagnosis code for the condition. It is relevant for coders, billers, clinical documentation staff, and others who need to understand how this rare neurologic disorder is represented in diagnosis coding and why it may appear in pediatric and respiratory/neurologic contexts.
Why This Topic Matters
Acute flaccid myelitis is uncommon but clinically important, and accurate diagnosis coding helps support documentation, reporting, and data tracking for cases that may involve significant neurologic impairment and respiratory complications.
