Displ transverse fx shaft of l tibia, 7thK

This code signifies a fracture of the shaft of the left tibia, specifically a transverse break that has resulted in displacement of the bone fragments. The "subsequent encounter" indicates that the patient is receiving follow-up care for this fracture, and "nonunion" means the bone fragments have failed to heal together after a reasonable period.

This code is appropriate for documenting ongoing treatment of a patient whose displaced transverse left tibial shaft fracture has not healed. This includes scenarios where surgical intervention for nonunion is being planned or has been performed, or when conservative management for nonunion is continuing.

• Ensure documentation clearly specifies "left" tibia and "transverse" fracture type.
• Verify that the encounter is for follow-up care and that nonunion is explicitly stated.
• Do not use for initial treatment or for fractures that are healing normally.
