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

This code describes a right ulna shaft fracture that is broken into at least three pieces (segmental), with the bone fragments out of alignment (displaced). The fracture has previously been treated, but the bone has healed incorrectly, resulting in a malunion.

Use this code for follow-up encounters where a patient is being treated for complications arising from a malunited, previously closed, displaced segmental fracture of the right ulnar shaft. This would include situations where the malunion is being assessed, monitored, or undergoing further intervention.

• Ensure documentation specifies "right arm" and "ulna" to differentiate from radial or bilateral injuries.
• Confirm "segmental" and "displaced" are clearly documented for accurate code selection.
• Verify the encounter is for a "subsequent encounter for closed fracture with malunion" and not an initial treatment or routine follow-up for a healing fracture without malunion.
