Displ pilon fx l tibia, subs for opn fx type I/2 w nonunion

This code describes a specific type of fracture affecting the distal end of the left tibia, known as a pilon fracture, which is displaced. It indicates that the fracture is an open fracture of either Type I or Type II severity, and the patient is in a subsequent phase of care where the fracture has failed to heal properly (nonunion).

Use this code for a patient presenting for follow-up care of a previously treated displaced pilon fracture of the left tibia. This is appropriate when the initial injury was an open fracture (Type I or II) and there is documented evidence of nonunion, meaning the bone fragments have not fused together as expected.

• Ensure documentation clearly specifies "left tibia" and "displaced pilon fracture."
• Verify the original injury was an "open fracture type I or II" and that the current encounter is for "nonunion."
• This code is for subsequent encounters; an initial encounter for this specific fracture would use a different code.
