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

This code signifies a bent bone deformity of the radius, specifically when the initial fracture has healed in an imperfect alignment (malunion). It indicates that the patient is presenting for follow-up care or treatment related to this established malunion, and the original fracture was a closed type.

Use this code for patients presenting with complications or ongoing issues due to a previously sustained, closed radial fracture that has healed with a noticeable angulation or bowing. This would apply during subsequent visits for monitoring, physical therapy, or consideration of corrective procedures for the malunion.

• Ensure documentation clearly states "malunion" and specifies the radius as the affected bone.
• Verify that the original fracture was closed and that this is a subsequent encounter for the malunion.
• Do not use for nonunion or acute fractures; those have different coding pathways.
