Acute paralytic poliomyelitis, wild virus, indigenous

This code signifies an acute neurological disorder characterized by sudden onset of flaccid paralysis due to infection with indigenous wild poliovirus. The virus attacks motor neurons in the spinal cord and brainstem, leading to muscle weakness and paralysis. This condition is a severe manifestation of poliovirus infection.

Use this code for patients presenting with acute flaccid paralysis confirmed to be caused by an indigenous wild poliovirus infection. Documentation should clearly state the presence of acute paralysis and laboratory confirmation of wild poliovirus, distinguishing it from vaccine-derived or imported strains. This code is appropriate when the infection originated within the patient's geographic region.

• Ensure documentation specifies "wild virus" and "indigenous" to differentiate from vaccine-associated or imported poliovirus.
• Do not use this code for post-polio syndrome or sequelae of poliomyelitis; separate codes exist for those conditions.
• Consider sequencing this code as the primary diagnosis when it is the reason for the encounter, followed by any associated complications.
