Smith's fx left radius, subs for opn fx type I/2 w malunion

This code signifies a Smith's fracture, an extra-articular fracture of the distal radius with volar displacement of the distal fragment, located in the left arm. Specifically, it indicates that the fracture was initially an open fracture of Type I or II, and the patient is now presenting for follow-up care due to malunion, meaning the bone has healed in an incorrect or deformed position.

Use this code for patients who have previously sustained an open Smith's fracture of the left radius (Type I or II) and are now being treated for complications arising from malunion. This would apply during subsequent visits for assessment, conservative management, or surgical correction of the malunion.

• Ensure documentation clearly specifies "Smith's fracture" and "left radius" to differentiate from other distal radius fractures.
• Verify the initial fracture was an "open fracture type I or II" and that the current encounter addresses "malunion."
• This code is for subsequent encounters; an initial encounter for a malunion would use a different seventh character.
