Osteopathy after poliomyelitis, left ankle and foot

This code describes a bone disorder, specifically osteopathy, that has developed in the left ankle and foot as a sequela of poliomyelitis. It indicates a chronic or late complication affecting the skeletal structure of the lower extremity due to a prior polio infection.

Use this code when documentation clearly states osteopathy in the left ankle and foot is a direct result of a previous poliomyelitis infection. This typically applies to patients presenting with skeletal deformities, pain, or functional limitations in the specified area attributed to polio. Supporting documentation should include a history of poliomyelitis and a diagnosis linking the osteopathy to this past infection.

• Always sequence this code after the appropriate code for the sequelae of poliomyelitis (e.g., B91).
• Ensure documentation specifies "osteopathy" and not just general musculoskeletal pain or weakness.
• Verify the laterality (left) and specific anatomical site (ankle and foot) are clearly documented.
