Smith's fracture of unsp radius, subs for clos fx w malunion

This code signifies a Smith's fracture, which is a reverse Colles' fracture involving the distal radius with volar displacement of the distal fragment. In this specific instance, the fracture has previously been treated and is now being managed for a malunion, meaning the bone has healed in an anatomically incorrect or deformed position, and the fracture was initially closed (skin intact). The specific side of the radius is not documented.

Use this code when a patient presents for follow-up care, evaluation, or treatment of a Smith's fracture of the radius that has healed in a misaligned position. This applies to situations where the initial fracture was closed and the current encounter addresses the complications or ongoing management of the malunion. It is appropriate when the medical record does not specify whether the left or right radius was affected.

• Ensure documentation clearly states "malunion" and that the initial fracture was closed.
• Verify that the fracture type is specifically a Smith's fracture, not another distal radius fracture.
• Only use this code when the laterality (left/right) of the affected radius is not specified in the medical record.
