Nondisp commnt fx shaft of rad, l arm, 7thR

This code describes a left radius shaft fracture that was initially an open fracture (Type IIIA, IIIB, or IIIC) but is now healing incorrectly, resulting in a malunion. The fracture itself is comminuted (broken into multiple pieces) and nondisplaced, meaning the bone fragments are still in their anatomical alignment despite the malunion.

This code is used for follow-up encounters where a patient is being treated for a malunion of a previously open, comminuted, nondisplaced fracture of the shaft of the left radius. This would apply when the physician is assessing the malunion, planning corrective surgery, or managing complications related to the improper healing.

• Ensure documentation clearly specifies "malunion" and the original fracture was an "open fracture type IIIA, IIIB, or IIIC."
• Verify the fracture is of the shaft of the radius and on the left arm.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
