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

This code signifies a fracture of the main part of the left lower leg bone, where the specific type of fracture is not documented. The injury is being treated, but the bone is not healing as quickly as expected, and the skin over the fracture remains intact.

Apply this code when a patient presents for follow-up care of a left tibial shaft fracture that was initially closed, and the physician documents delayed healing without specifying the fracture type (e.g., transverse, oblique, spiral). This is appropriate for subsequent visits after the initial treatment of the fracture.

• Ensure documentation explicitly states "delayed healing" for a closed left tibial shaft fracture.
• Verify that this is a subsequent encounter, not the initial treatment of the fracture.
• Only use this code if the specific fracture type of the shaft is not documented.
