Oth fx lower end of l tibia, subs for clos fx w delay heal

This code signifies a fracture affecting the lower portion of the left tibia, excluding the malleoli, that is currently in a healing phase but is progressing slower than expected. The fracture was initially treated without surgery (closed reduction or non-surgical management).

Apply this code when a patient presents for follow-up care of a left distal tibia fracture (not involving the ankle malleoli) that was previously managed non-surgically, and the physician documents delayed union or healing. This is appropriate for subsequent visits where the fracture is still present but not healing at the anticipated rate.

• Ensure documentation explicitly states "delayed healing" or "delayed union" for a closed fracture.
• Verify the fracture location is the lower end of the tibia, excluding specific malleolar fractures.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
