Displ commnt fx shaft of ulna, r arm, 7thM

This code signifies a complex fracture of the right ulna, specifically involving the shaft, where the bone has broken into multiple pieces and the fragments are not properly aligned. Furthermore, the initial injury was an open fracture (meaning the skin was broken), and despite previous treatment, the bone has failed to heal, resulting in a nonunion.

This code is appropriate for documenting follow-up care for a patient with a previously treated open comminuted fracture of the right ulnar shaft that has not healed. It should be used when the patient is presenting for ongoing management of this nonunion, such as for surgical intervention, cast changes, or evaluation of healing progress.

• Ensure documentation clearly specifies "right arm" and "ulna shaft" to differentiate from other forearm fractures.
• Verify the original fracture was an "open fracture type I or II" and that "nonunion" is explicitly documented.
• Confirm this is a "subsequent encounter" for the nonunion, not the initial treatment of the fracture.
