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

This code describes a Smith's fracture, which is a reverse Colles' fracture involving the distal radius with volar (palmar) displacement of the distal fragment. Specifically, it indicates that the fracture is on the right side, was an open fracture (Type I or II), and is now being treated for a malunion, meaning the bone has healed in an incorrect anatomical position.

Use this code when a patient presents for follow-up care, surgical correction, or management of complications related to a malunited Smith's fracture of the right radius. This applies when the original injury was an open fracture of either Type I or Type II severity.

• Confirm the laterality (right) and the specific type of fracture (Smith's) from the documentation.
• Ensure the encounter is for a "subsequent encounter" and that malunion is explicitly documented as the reason for the visit.
• Verify that the original fracture was an open Type I or Type II; if it was Type III or unspecified open, a different code would be appropriate.
