Pathological fracture, left radius, subs for fx w malunion

This code signifies a fracture of the left radius that occurred due to an underlying disease process, rather than trauma. The patient is currently receiving care for this pathological fracture, and the fracture has healed improperly, resulting in a malunion. This indicates a complication of the healing process requiring ongoing management.

Use this code when documentation specifies a pathological fracture of the left radius, and the patient is being treated for a malunion of that fracture. This applies to follow-up visits, cast changes, or other ongoing care related to the improperly healed fracture. Physician notes should clearly state "pathological fracture," "left radius," and "malunion" in the context of a subsequent encounter.

• Ensure documentation explicitly states "pathological fracture" to differentiate from traumatic fractures.
• Verify the laterality (left radius) is clearly documented.
• Confirm the encounter is for ongoing care of the malunion, not the initial treatment or a sequela.
