Displ commnt fx shaft of unsp tibia, 7thM

This code describes a complex fracture of the main part of the shin bone (tibia) that has broken into multiple pieces and is no longer in its normal alignment. It specifically indicates that the skin was broken (an open fracture, type I or II) and that the bone is failing to heal properly (nonunion) during a follow-up visit.

This code is used for subsequent encounters when a patient is being treated for a previously diagnosed open comminuted fracture of the tibial shaft that has developed nonunion. This would apply during follow-up appointments for ongoing management, surgical planning for nonunion, or monitoring of conservative treatment for nonunion.

• Ensure documentation clearly specifies "nonunion" and "subsequent encounter" for this specific fracture type.
• Verify the open fracture type (I or II) is documented; if not specified, query the provider.
• Confirm the fracture is of the "shaft" of the tibia, as other anatomical locations have different codes.
