Unsp fx shaft of unsp radius, subs for clos fx w malunion

This code indicates a fracture of the shaft of the radius where the specific location (e.g., proximal, distal) is not documented, and the later healing process has resulted in an abnormal alignment of the bone fragments. This is a follow-up encounter for a fracture that was initially treated non-surgically and has now healed incorrectly.

Use this code for a patient presenting for follow-up care of a previously diagnosed closed radial shaft fracture that has healed with malunion, and the documentation does not specify which radius (left or right) or the exact part of the shaft. This applies when the patient is still receiving active treatment for the malunion, such as physical therapy, or is being evaluated for corrective surgery.

• Ensure documentation clearly states "malunion" and that it's a subsequent encounter for a closed fracture.
• If the laterality (left/right) or specific part of the radial shaft is documented, a more specific code should be used.
• Always review the entire medical record to confirm the encounter type and the status of the fracture healing.
