Displ trimalleol fx l low leg, 7thH

This code signifies a complex ankle fracture involving all three malleoli (medial, lateral, and posterior) of the left lower leg, where the bone fragments are not properly aligned. It specifically indicates that the fracture broke through the skin (open fracture type I or II) and is currently experiencing a slower-than-expected healing process.

Use this code for follow-up encounters when a patient with a previously diagnosed displaced trimalleolar open fracture of the left lower leg (Gustilo-Anderson Type I or II) is presenting with evidence of delayed union. This applies during ongoing treatment, such as cast changes, wound care, or physical therapy, when the fracture has not healed within the expected timeframe.

• Ensure documentation clearly specifies "left" lower leg and "trimalleolar" involvement.
• Verify the "subsequent encounter" status and the "delayed healing" complication.
• Confirm the original fracture was documented as an "open fracture type I or II."
