Displ spiral fx shaft of ulna, l arm, 7thN

This code signifies a left ulna fracture, specifically a spiral break in the shaft, where the bone fragments are no longer in their normal alignment. It indicates that the patient is receiving follow-up care for a severe open fracture (Type IIIA, IIIB, or IIIC) that has failed to heal properly.

Use this code for patients presenting for ongoing treatment, such as cast changes, wound care, or surgical planning, for a previously diagnosed open spiral fracture of the left ulnar shaft that has developed nonunion. This applies when the initial injury was classified as a severe open fracture.

• Ensure documentation clearly specifies "left arm" and "ulna" to differentiate from other forearm bones or sides.
• Verify the fracture is explicitly described as "spiral" and "displaced" in the clinical notes.
• Confirm the encounter is for a "subsequent" visit and that the original open fracture was classified as Type IIIA, IIIB, or IIIC.
