Smith's fx left rad, subs for opn fx type I/2 w delay heal

This code signifies a Smith's fracture, which is a reverse Colles' fracture involving the distal end of the radius with volar (palmar) displacement, specifically affecting the left arm. The fracture is an open type I or II, meaning there is a break in the skin communicating with the fracture, and the patient is in a phase of treatment where the healing process is slower than expected.

This code is appropriate for follow-up encounters for a patient with a previously diagnosed and treated open Smith's fracture of the left radius (Type I or II) who is experiencing delayed union or healing. It would be used when the patient presents for ongoing management, such as cast changes, wound care, or assessment of healing progress, and the fracture is not healing at the anticipated rate.

• Ensure documentation clearly specifies "Smith's fracture" and "left radius," as well as "open fracture type I or II."
• The "H" seventh character indicates a subsequent encounter for delayed healing; confirm this status is documented.
• Distinguish from nonunion (K) or malunion (M) which have separate seventh characters.
