Nondisp transverse fx shaft of unsp ulna, 7thP

This code describes a situation where a patient has a transverse fracture in the shaft of their ulna, which was not displaced at the time of injury. The fracture is now in a later stage of healing, but has healed incorrectly, resulting in a malunion. The specific ulna (left or right) is not documented.

This code is used when a patient presents for follow-up care of a previously diagnosed closed ulnar shaft fracture that has healed in an unsatisfactory alignment. It is appropriate for subsequent encounters where the malunion is being assessed or managed, and the initial injury was a nondisplaced transverse fracture.

• Ensure documentation clearly states "malunion" and specifies a "subsequent encounter."
• Verify the fracture was initially "nondisplaced" and "transverse" in the ulnar shaft.
• Do not use this code if the laterality (left or right ulna) is specified in the documentation; a more specific code would be available.
