Sequelae of poliomyelitis

This code represents the long-term neurological and musculoskeletal complications that arise as a direct result of a prior poliomyelitis infection. These sequelae are permanent and can include muscle weakness, paralysis, joint deformities, and chronic pain, occurring years after the initial acute illness. It signifies the residual effects of the poliovirus on the central nervous system.

Use this code when documentation clearly indicates a patient is experiencing chronic, stable impairments directly attributable to a past poliomyelitis infection. This typically applies to individuals who contracted polio in childhood and are now presenting with persistent physical limitations. Supporting documentation should specify a history of poliomyelitis and current related neurological or musculoskeletal deficits.

• Do not code this with G14 (Postpolio syndrome); these are distinct conditions.
• Always sequence this code after the acute condition or primary reason for the encounter, if applicable, as it describes a chronic sequela.
• Ensure documentation differentiates between general muscle weakness and weakness specifically attributed to a prior polio infection.
