Nondisp pilon fx unsp tibia, 7thM

This code describes a pilon fracture of the tibia that is not displaced, meaning the bone fragments remain in their normal alignment. It specifically indicates a subsequent encounter for an open fracture (where the skin was broken) that was initially classified as Type I or II, and is now complicated by nonunion, meaning the bone is failing to heal.

Use this code for follow-up care of a patient with a previously treated open pilon fracture (Gustilo-Anderson Type I or II) of the tibia that has not healed. This applies when the fracture fragments are still in good alignment but bone healing has ceased or is significantly delayed. This code is appropriate for encounters addressing the ongoing management of the nonunion.

• Ensure documentation clearly states "nondisplaced" and "nonunion" for a pilon fracture of the tibia.
• Verify the initial open fracture was classified as Type I or II.
• This code is for subsequent encounters, not the initial treatment of the fracture.
