Pathological fracture, right ulna, sequela

This code describes a pathological fracture of the right ulna that has resulted in a long-term complication or condition. This indicates a fracture that occurred due to an underlying disease weakening the bone, and the "sequela" denotes a residual effect or late complication of that original fracture.

Apply this code when documentation clearly indicates a pathological fracture of the right ulna and the patient is presenting for treatment or evaluation of a chronic condition or late effect directly resulting from that fracture. This is used after the initial healing phase of the fracture has passed. Supporting documentation would include notes detailing the original pathological fracture and the current sequela.

• Do not use for initial or subsequent encounters for the acute fracture; those would use codes from the M84.431- series without the "S" seventh character.
• Always sequence this code after the code for the underlying condition that caused the pathological fracture (e.g., osteoporosis, neoplasm).
• Ensure documentation specifies "right ulna" and clearly identifies the current condition as a sequela of the original pathological fracture.
