Displ seg fx shaft of ulna, l arm, 7thP

This code signifies a left ulnar shaft fracture that has broken into multiple segments and is no longer in proper alignment. It specifically indicates that the patient is returning for follow-up care of this closed fracture, and the bone has healed in an unsatisfactory position (malunion).

Apply this code for patients presenting for ongoing management of a previously sustained, non-surgically treated left ulnar shaft fracture where imaging confirms a segmental break and the fracture has healed with a noticeable deformity or angulation. This is appropriate for subsequent visits after the initial treatment, focusing on the complications of malunion.

• Ensure documentation clearly specifies "left arm" and "ulna" to differentiate from radial or other arm fractures.
• Verify that the encounter is for "subsequent care" and not the initial treatment or a sequela.
• Confirm the presence of "malunion" as opposed to nonunion or routine healing.
