Displ transverse fx shaft of unsp rad, 7thR

This code describes a situation where a patient has a transverse fracture of the shaft of an unspecified radius that was initially an open fracture (Type IIIA, IIIB, or IIIC) and is now being treated for malunion. Malunion indicates that the fracture has healed, but in an unsatisfactory position, leading to functional impairment or cosmetic deformity.

Use this code when documenting follow-up care for a patient with a previously diagnosed open transverse radial shaft fracture (of an unspecified side) that has healed incorrectly. This applies to encounters where the malunion itself is the focus of treatment or evaluation, such as for corrective osteotomy planning or assessment of ongoing functional limitations due to the malunion.

• Ensure documentation clearly specifies "malunion" and the "subsequent encounter" for this condition.
• Verify the original fracture was an open fracture classified as Type IIIA, IIIB, or IIIC.
• Do not use for nonunion; a different code would be appropriate for a fracture that has failed to heal.
