Osteopathy after poliomyelitis, unspecified thigh

This code signifies a bone disorder, specifically osteopathy, that develops as a long-term complication following a poliomyelitis infection, affecting an unspecified area of the thigh. It indicates a pathological change in bone structure or density attributable to the sequelae of polio.

Use this code when documentation clearly links a patient's osteopathy in the thigh to a history of poliomyelitis. This diagnosis is appropriate for conditions such as osteoporosis, osteomalacia, or other bone deformities in the thigh that are a direct result of the polio infection.

• Ensure documentation specifies "osteopathy" and a causal link to poliomyelitis.
• If the specific thigh (right or left) is documented, use the more specific codes M89.651 or M89.652.
• Always code the underlying poliomyelitis sequelae (e.g., G14) first, if still active or relevant to the current encounter.
