Bent bone of left radius, subs for clos fx w malunion

This code signifies a bent bone deformity of the left radius that occurred as a complication of a previously sustained closed fracture. The "bent bone" indicates a malunion, meaning the fracture healed in an anatomically incorrect or misaligned position, leading to a visible or palpable deformity. This specific code is used when the patient is receiving follow-up care for this established malunion.

Apply this code when a patient presents for ongoing management, evaluation, or treatment of a malunited closed fracture of the left radius, where the malunion manifests as a bent bone deformity. This would include visits for assessing functional limitations, planning corrective surgery, or monitoring the progression of the deformity after initial healing. It is appropriate for any encounter following the initial treatment of the fracture and the diagnosis of the malunion.

• Ensure documentation clearly specifies "bent bone" as the type of malunion and confirms the left radius as the affected bone.
• Verify that the encounter is for subsequent care of the malunion, not the initial fracture treatment.
• Pair with external cause codes (e.g., V-codes) if the original injury's cause is relevant to the current encounter.
