Nondisp seg fx shaft of ulna, r arm, 7thQ

This code describes a healed or healing fracture of the right ulnar shaft that was originally an open fracture (Type I or II) and has resulted in malunion. The fracture itself was segmental and nondisplaced. The malunion indicates the bone has healed in an abnormal position, potentially impacting function.

This code is used for follow-up encounters when a patient presents with a previously treated open segmental shaft fracture of the right ulna that has healed with malunion. It is appropriate for situations where the malunion is being monitored, evaluated for further intervention, or is a contributing factor to ongoing symptoms.

• Ensure documentation clearly specifies "malunion" and not "nonunion" for accurate code selection.
• Verify the laterality (right arm) and the specific bone (ulna shaft) are documented.
• Confirm the original fracture was an open fracture type I or II, as this impacts the seventh character.
