Displ pilon fx r tibia, 7thN

This code describes a complex fracture involving the weight-bearing surface of the distal right tibia (pilon fracture) that is no longer in its anatomical alignment. This specific instance indicates a subsequent visit for an open fracture, classified as Type IIIA, IIIB, or IIIC, where the bone fragments have failed to heal together after a previous treatment attempt.

Use this code for follow-up encounters with a patient who has a previously treated, but now unhealed, displaced open pilon fracture of the right tibia. This applies when the open fracture was initially severe (Type IIIA, IIIB, or IIIC) and the current visit addresses the nonunion. This code would be appropriate for ongoing management, surgical planning for revision, or assessment of the nonunion.

• Ensure documentation clearly specifies "nonunion" and the "displaced" nature of the pilon fracture.
• Verify the encounter is "subsequent" and not the initial treatment for the fracture.
• Confirm the original open fracture was classified as Type IIIA, IIIB, or IIIC to accurately assign this specific code.
