Osteopathy after poliomyelitis, left upper arm

This code describes a bone disorder, specifically osteopathy, that has developed in the left upper arm as a sequela of a previous poliomyelitis infection. It indicates a chronic or late-onset musculoskeletal complication directly attributable to the polio.

Use this code when documentation clearly states a diagnosis of osteopathy in the left upper arm and explicitly links it to a history of poliomyelitis. This typically applies to patients presenting with bone pain, deformity, or functional impairment in the left upper arm, where the etiology is determined to be post-polio.

• Ensure documentation specifies "osteopathy" and not another bone condition.
• Verify the laterality is precisely "left upper arm" to avoid miscoding.
• Always sequence this code after the code for the underlying poliomyelitis sequelae (e.g., B91) if applicable and still active.
