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

This code describes a Smith's fracture, which is a reverse Colles' fracture involving the distal radius with volar displacement of the distal fragment. This specific code is for an open fracture (Type I or II) of an unspecified radius that is currently in a phase of delayed healing, meaning the fracture is not healing at the expected rate.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed open Smith's fracture of the radius (Type I or II) is presenting for ongoing management due to delayed union. It should be used when the physician documents that the fracture healing is not progressing as anticipated.

• Requires an additional code for any associated open wound infection if present.
• Confirm documentation specifies "delayed healing" for an open fracture type I or II.
• Do not use for initial fracture treatment or for routine follow-up of a healing fracture.
