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

This code describes a left ulnar shaft fracture that is broken in at least two places (segmental) and has not shifted out of alignment. This specific code is used when the fracture was initially an open fracture (skin broken) of type I or II, and the patient is now being seen for a complication where the bone has healed incorrectly (malunion).

Apply this code when documenting follow-up care for a patient with a previously sustained open segmental ulna shaft fracture on the left arm that has healed in an unsatisfactory position. This is appropriate for encounters addressing the malunion itself, or for ongoing management of the limb affected by the malunion.

• Ensure documentation clearly specifies "left arm" and "segmental" fracture of the ulna shaft.
• Verify the initial injury was an "open fracture type I or II" and that "malunion" is explicitly diagnosed.
• This "Q" seventh character indicates a subsequent encounter for a complication, not the initial treatment of the fracture.
