Displ commnt fx shaft of rad, unsp arm, 7thR

This code describes a situation where a patient has a comminuted fracture of the radius shaft, meaning the bone is broken into multiple fragments, and these fragments are not properly aligned. This particular encounter is for an open fracture (where the bone broke through the skin) that has developed malunion, indicating the fracture has healed in an incorrect or deformed position. The open fracture is further specified as Type IIIA, IIIB, or IIIC, denoting significant soft tissue damage.

Use this code for follow-up encounters when a patient is being treated for a previously sustained, displaced, comminuted open fracture of the radial shaft (unspecified arm) that has healed improperly. This applies when the original open fracture was classified as Type IIIA, IIIB, or IIIC and the current encounter addresses the resulting malunion. This code would be appropriate for surgical correction of the malunion or ongoing management of its complications.

• Ensure documentation clearly specifies "malunion" and the original open fracture type (IIIA, IIIB, or IIIC).
• Verify the fracture is of the shaft of the radius, not the distal or proximal end.
• Confirm this is a "subsequent encounter" for the malunion, not the initial treatment of the fracture.
