Nondisp transverse fx shaft of l ulna, 7thP

This code describes a situation where a patient has a transverse fracture in the shaft of their left ulna that was not displaced at the time of injury, but has subsequently healed incorrectly (malunion). This specific code is used during a follow-up visit where the malunion is being addressed or monitored.

This code is appropriate for subsequent encounters when a patient presents with a previously diagnosed nondisplaced transverse fracture of the left ulnar shaft that has healed with a malunion. This could include visits for assessment of the malunion, planning for corrective surgery, or ongoing management of symptoms related to the malunion.

• Ensure documentation clearly states "malunion" and specifies the left ulna and transverse fracture type.
• Verify that the encounter is "subsequent" and not the initial treatment for the fracture.
• Always sequence this code after the primary reason for the encounter, if applicable.
