Nondisp pilon fx r tibia, 7thN

This code describes a pilon fracture of the right tibia that is not displaced, meaning the bone fragments are still in their normal anatomical alignment. It specifically indicates a subsequent encounter for an open fracture (where the bone broke through the skin) classified as type IIIA, IIIB, or IIIC, and is complicated by nonunion, meaning the fracture has failed to heal after a reasonable period.

Use this code when documenting follow-up care for a patient with a previously treated open pilon fracture of the right tibia, where the fracture was initially severe (Type IIIA, IIIB, or IIIC) and has now developed nonunion. This applies to ongoing management, such as repeat imaging, surgical planning for nonunion repair, or conservative management of the nonunion.

• Ensure documentation clearly specifies "nondisplaced" and "right tibia" for accurate laterality and displacement.
• Verify the original fracture was an open fracture type IIIA, IIIB, or IIIC, as this significantly impacts code selection.
• Confirm "nonunion" is explicitly documented by the provider, indicating a failure of the fracture to heal.
