Displ oblique fx shaft of unsp tibia, 7thQ

This code describes a tibia shaft fracture that is both displaced and oblique in nature, meaning the bone fragments are out of alignment and the break runs diagonally across the bone. This specific code is used during a subsequent encounter for an open fracture (Type I or II) that has healed incorrectly, resulting in malunion.

This code is appropriate when a patient presents for follow-up care of a previously treated open tibia shaft fracture (Gustilo-Anderson Type I or II) where imaging or clinical assessment confirms malunion. This indicates the bone has healed in an unsatisfactory position, potentially requiring further intervention.

• Ensure documentation clearly specifies "malunion" and the open fracture type (I or II) from the initial injury.
• Verify the fracture is of the "shaft" of the tibia, not the proximal or distal ends.
• Confirm the fracture is "displaced" and "oblique" based on radiographic reports.
