Late effects of acute poliomyelitis

This code represents the long-term or residual neurological and musculoskeletal sequelae resulting from a prior acute poliomyelitis infection. These late effects manifest after the acute phase of the disease has resolved, often years later, and can include muscle weakness, paralysis, atrophy, and skeletal deformities. It signifies the chronic impact of the poliovirus on the nervous system.

Use this code when documenting conditions directly attributable to a past poliomyelitis infection, such as post-polio syndrome, progressive muscle weakness, or joint deformities in a patient with a confirmed history of polio. Documentation should clearly state the link between the current condition and a previous polio diagnosis, often including a history of acute flaccid paralysis.

• Always sequence this code after the specific manifestation code (e.g., muscle weakness, paralysis) if applicable.
• Do not use this code for acute poliomyelitis; it is exclusively for late effects.
• Ensure the medical record explicitly states a history of poliomyelitis and links the current symptoms to this past infection.
