Displ transverse fx shaft of unsp ulna, 7thQ

This code describes a situation where a patient has a transverse fracture of the shaft of an unspecified ulna that was initially an open fracture (Type I or II) and has subsequently healed in an imperfect or misaligned position (malunion). This specific code is used for follow-up care related to this malunited open fracture.

Use this code for subsequent encounters when a patient is being treated for complications arising from a malunited transverse fracture of the ulnar shaft, which was originally an open fracture. This includes scenarios where the malunion is causing functional impairment or pain, and the patient is undergoing evaluation or treatment for this specific issue.

• Ensure the documentation clearly specifies a transverse fracture of the ulnar shaft and a malunion as the current issue.
• Verify the original fracture was documented as an open fracture Type I or II.
• This "Q" seventh character indicates a subsequent encounter for a malunion, not initial treatment or routine follow-up without complications.
