Displ pilon fx unsp tibia, 7thM

This code signifies a pilon fracture of the tibia, which is a break at the weight-bearing surface of the distal tibia, that is displaced. It specifically indicates that the fracture was initially an open fracture of type I or II and is now experiencing nonunion, meaning the bone fragments are failing to heal together, during a subsequent phase of care.

Apply this code when documenting ongoing treatment for a patient with a previously sustained open pilon fracture (Gustilo-Anderson Type I or II) of an unspecified tibia, where the fracture remains displaced and has not achieved bony union. This is appropriate for follow-up visits, cast changes, or surgical interventions addressing the nonunion.

• Ensure documentation clearly specifies "nonunion" and the initial open fracture type (I or II).
• Confirm the fracture is still displaced, as this is a key component of the code.
• This code is for subsequent encounters; use an initial encounter code for the acute injury.
