Displ pilon fx l tibia, 7thN

This code signifies a complex fracture of the distal end of the left tibia, specifically involving the joint surface (pilon fracture), which is out of alignment. It indicates that the fracture is open, meaning the skin and soft tissues are severely compromised, and the bone fragments have failed to heal together after an initial treatment. This particular code is used during follow-up care for this non-healing open fracture.

Apply this code when documenting subsequent encounters for a patient with a previously diagnosed displaced pilon fracture of the left tibia. The key criteria are the open nature of the fracture (Type IIIA, IIIB, or IIIC) and the confirmed diagnosis of nonunion, indicating a failure of the bone to mend. This code would be used during ongoing management, such as for surgical planning for revision, infection control, or continued wound care related to the nonunion.

• Ensure documentation clearly specifies "left" tibia and "displaced" pilon fracture.
• Confirm the fracture is explicitly documented as an "open fracture type IIIA, IIIB, or IIIC" and that "nonunion" is present.
• This code is for subsequent encounters; use an initial encounter code for the first presentation of the fracture.
