Oth fx shaft of rad, unsp arm, 7thR

This code signifies a complex fracture of the main part of the radius bone, where the specific location on the shaft is not detailed, and the affected arm is also unspecified. It indicates that the fracture was initially an open fracture of a severe type (IIIA, IIIB, or IIIC) and is now being treated for malunion, meaning the bone has healed incorrectly.

This code is appropriate for documenting follow-up care for a patient who previously sustained a severe open fracture of the radial shaft, and the current encounter addresses complications related to malunion. This would include scenarios where surgical correction of the malunion is being planned or performed, or during ongoing management of the improperly healed bone.

• Ensure documentation clearly specifies "malunion" as the reason for the subsequent encounter.
• Verify that the original fracture was indeed an open fracture classified as type IIIA, IIIB, or IIIC.
• Do not use this code for nonunion; a different code exists for that complication.
