Smith's fx left rad, subs for opn fx type 3A/B/C w malunion

This code signifies a Smith's fracture of the left radius that is currently undergoing treatment for a malunion. The original fracture was an open fracture, specifically a Type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and bone exposure. The malunion means the bone has healed in an anatomically incorrect position.

Use this code when a patient presents for follow-up care, such as clinic visits, cast changes, or physical therapy, for a left radial Smith's fracture that has healed with malunion. This applies when the initial injury was an open fracture of the specified types. It is appropriate for ongoing management of the malunion, including assessment for corrective osteotomy or other interventions.

• Ensure documentation clearly specifies a Smith's fracture of the left radius and confirms malunion.
• Verify the original fracture was an open fracture classified as Type IIIA, IIIB, or IIIC.
• This code is for subsequent encounters, not the initial treatment of the fracture or malunion.
