Oth fx low end l tibia, subs for opn fx type I/2 w malunion

This code signifies a fracture of the lower portion of the left shin bone, excluding the ankle, that has not healed correctly (malunion). It specifically applies to cases where the initial injury was an open fracture, meaning the bone broke through the skin, and the patient is now receiving follow-up care for this complication.

Utilize this code when documenting subsequent treatment for a patient with a malunited fracture of the distal left tibia, where the original fracture was an open type I or II. This includes scenarios such as surgical correction of the malunion, cast changes, or ongoing physical therapy related to the improperly healed bone.

• Ensure documentation clearly specifies "malunion" and the "subsequent encounter" for the fracture.
• Verify the original fracture was an "open type I or II" to accurately assign this specific code.
• Distinguish from nonunion (complete failure to heal) or routine follow-up for a properly healing fracture.
