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

This code signifies a Smith's fracture, which is a reverse Colles' fracture involving the distal radius with volar displacement, specifically affecting the right arm. The fracture is an open type I or II, meaning there is a wound communicating with the fracture site, and the bone fragments have failed to heal properly after an initial treatment. This code is used during subsequent encounters for ongoing management of this nonunion.

This code is appropriate for follow-up visits where a patient with a previously diagnosed and treated open Smith's fracture of the right radius is being managed for a confirmed nonunion. It should be used when the patient is receiving continued care, such as cast changes, wound care, or surgical planning for the nonunion. Do not use this code for the initial treatment of the fracture or for routine follow-up of a healing fracture.

• Ensure documentation clearly specifies "Smith's fracture" and "right radius" to differentiate from other distal radius fractures.
• Verify the fracture is explicitly documented as "open type I or II" and that "nonunion" is confirmed and being addressed.
• This code requires an additional code for any associated external cause of injury.
