Acute paralytic poliomyelitis, unspecified

This code signifies an acute onset of poliomyelitis characterized by flaccid paralysis, where the specific type of poliovirus causing the infection is not documented. It indicates a severe neurological manifestation of the disease, leading to muscle weakness and loss of motor function.

Apply this code when documentation confirms a diagnosis of acute paralytic poliomyelitis, but the medical record does not specify whether it's vaccine-associated, wild poliovirus, or other specified types. This code is appropriate when the paralysis is clearly attributed to a recent poliovirus infection.

• Do not use if the type of poliovirus is specified (e.g., wild poliovirus, vaccine-associated).
• Ensure documentation clearly states "acute" and "paralytic" poliomyelitis.
• Consider sequencing this code as the primary diagnosis if it is the reason for the encounter.
