Unsp fx shaft of left radius, subs for clos fx w delay heal

This code signifies a fracture of the main part of the left radius bone, where the specific type of fracture is not documented. The patient is in a later phase of treatment for this injury, and the fracture is closed (skin intact) but is not healing as expected within the typical timeframe.

Apply this code when a patient presents for follow-up care of a left radial shaft fracture that was initially treated conservatively or surgically, and the physician notes delayed union or non-union of the fracture. This code is appropriate when the specific fracture pattern (e.g., transverse, oblique) was not documented at the initial encounter or is not relevant to the current delayed healing status.

• Ensure documentation clearly states "delayed healing" or similar terminology for a closed fracture.
• Verify the encounter is subsequent, not initial, for this specific injury.
• Only use this code if the specific fracture type of the radial shaft is truly unspecified in the medical record.
