Osteopathy after poliomyelitis, left forearm

This code signifies a bone disorder or disease (osteopathy) that develops as a sequela of poliomyelitis, specifically affecting the patient's left forearm. It indicates a pathological change in the bone structure attributed to the long-term effects of polio.

Apply this code when documentation clearly states a diagnosis of osteopathy in the left forearm, and explicitly links it as a complication or residual effect of a previous poliomyelitis infection. Supporting documentation should detail the bone pathology and its connection to the patient's polio history.

• Ensure the documentation specifies "left forearm" and not another anatomical site.
• Verify the causal link between the osteopathy and prior poliomyelitis; avoid using for unrelated bone conditions.
• Consider sequencing with a code for the history of poliomyelitis (e.g., B91) if relevant for the encounter.
