Pathological fracture, right humerus, sequela

This code signifies a pathological fracture of the right humerus where the acute phase of the fracture has passed, and the patient is now experiencing a residual effect or complication from the original fracture. This could include nonunion, malunion, chronic pain, or functional impairment directly attributable to the healed or healing pathological fracture.

Apply this code when documentation indicates a patient is being treated for a long-term complication or residual condition stemming from a pathological fracture of the right humerus that occurred in the past. This is appropriate for follow-up care, rehabilitation, or management of chronic issues related to the previous fracture. Documentation should clearly state the "sequela" or "late effect" of the pathological fracture.

• Always sequence this code after the code describing the specific sequela (e.g., M96.0 for pseudarthrosis after fusion).
• Do not use this code for an active, acute pathological fracture; instead, use the appropriate acute pathological fracture code (e.g., M84.421A-K).
• Ensure documentation specifies "right humerus" and clearly links the current condition to a past pathological fracture.
