Displ pilon fx l tibia, 7thR

This code signifies a pilon fracture of the left tibia that is displaced and has previously been treated, but has healed in an abnormal position (malunion). The original injury was an open fracture, classified as Type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and bone exposure.

Use this code when documenting follow-up care for a patient with a malunited displaced pilon fracture of the left tibia, where the initial injury was a severe open fracture. This would apply to scenarios such as surgical correction of the malunion or ongoing management of complications related to the malunion.

• Ensure documentation clearly specifies "malunion" and the "left tibia."
• Verify the original open fracture type (IIIA, IIIB, or IIIC) is documented or can be inferred from prior records.
• Confirm this is a "subsequent encounter" for the malunion, not the initial treatment of the fracture.
