Osteopathy after poliomyelitis, unspecified ankle and foot

This code describes a bone disorder that develops as a sequela of poliomyelitis, affecting an unspecified ankle and/or foot. It indicates a chronic or late-onset musculoskeletal complication directly attributable to a prior polio infection, manifesting as osteopathic changes in the lower extremity.

Use this code when documentation clearly states a diagnosis of osteopathy in the ankle or foot that is a direct consequence of a previous poliomyelitis infection. This diagnosis should be supported by clinical findings and patient history linking the bone changes to the polio.

• Ensure documentation explicitly links the osteopathy to a history of poliomyelitis.
• Avoid using this code if the osteopathy is due to other causes; investigate for more specific codes.
• Sequence this code after the code for the underlying poliomyelitis sequelae, if applicable.
