Path fracture, unsp ulna and radius, subs for fx w malunion

This code signifies a fracture of both the ulna and radius that occurred due to a pre-existing disease or condition, rather than trauma. The patient is in a subsequent phase of care for this pathological fracture, and the fracture has healed improperly, resulting in a malunion. This indicates ongoing management of the poorly aligned bone healing.

Use this code when documentation clearly states a pathological fracture of both the ulna and radius, and the patient is being seen for follow-up care specifically addressing a malunion. This code is appropriate for encounters where the primary focus is the management of the malunited fracture after initial treatment. Supporting documentation should include imaging reports confirming malunion and physician notes detailing the pathological nature of the original fracture.

• Ensure documentation specifies "pathological fracture" and not just a traumatic fracture.
• Verify that the encounter is for the subsequent care of the fracture with a malunion, not initial treatment or routine follow-up without complications.
• Always sequence this code after the underlying disease responsible for the pathological fracture, if applicable and still active.
