Nondisp spiral fx shaft of ulna, l arm, 7thR

This code describes a specific type of fracture involving the shaft of the left ulna, characterized by a spiral break that has not shifted out of alignment. It indicates that the patient is in a subsequent phase of care for an open fracture (where the bone broke through the skin) classified as type IIIA, IIIB, or IIIC, and is now experiencing malunion, meaning the bone is healing in an incorrect anatomical position.

This code is appropriate for documenting follow-up care for a patient with a previously treated open spiral fracture of the left ulnar shaft, specifically when the fracture was severe (type IIIA, IIIB, or IIIC) and has healed or is healing with a noticeable deformity or misalignment. It should be used when the focus of the encounter is on managing the malunion during the recovery period.

• Ensure documentation clearly specifies "nondisplaced spiral fracture" of the ulnar shaft and identifies the left arm.
• Verify that the initial injury was an open fracture of type IIIA, IIIB, or IIIC, and that the current encounter addresses malunion.
• Do not use this code for initial treatment of the fracture or for encounters where the fracture is still acute and not yet showing signs of malunion.
