Oth fx shaft of rad, l arm, 7thR

This code signifies a malunion of an open fracture of the shaft of the left radius, specifically an open fracture classified as Type IIIA, IIIB, or IIIC. Malunion indicates that the bone has healed, but in an unsatisfactory or deformed position.

This code is used for follow-up encounters where a patient is being treated for a previously diagnosed open fracture of the left radial shaft that has healed incorrectly. It applies when the original open fracture was severe (Type IIIA, IIIB, or IIIC) and the current encounter addresses the resulting malunion.

• Ensure documentation specifies "malunion" and not "nonunion" or "delayed healing."
• Verify the original open fracture was of the shaft of the radius and involved the left arm.
• Confirm the original open fracture type (IIIA, IIIB, or IIIC) is documented to support the specificity of this code.
