Stress fracture, right radius, subs for fx w malunion

This code signifies a stress fracture of the right radius that has previously been treated but has healed improperly, resulting in a malunion. The patient is currently receiving care for this established malunion of the stress fracture.

Use this code when a patient presents for ongoing management or treatment of a right radial stress fracture that has healed in a misaligned or deformed position. Documentation should clearly indicate a prior stress fracture, evidence of malunion (e.g., imaging reports, physician notes describing deformity or functional impairment), and that the current encounter is for the malunion itself, not the initial fracture treatment.

• Ensure documentation explicitly states "malunion" and specifies the right radius.
• This code is for subsequent encounters; avoid using it for initial treatment of the stress fracture or for nonunion.
• Always review imaging reports and physician notes for confirmation of malunion and laterality.
