Displ commnt fx shaft of ulna, unsp arm, 7thQ

This code describes a situation where a patient has a comminuted fracture of the ulna shaft that is no longer in proper alignment (displaced) and has healed incorrectly (malunion). This specific encounter is for an open fracture, meaning the skin was broken at the time of injury, classified as Type I or II.

Use this code when documenting follow-up care for a patient with a previously treated open comminuted ulna shaft fracture that has now healed in a misaligned position. This applies to subsequent encounters where the malunion is being addressed or monitored, following the initial treatment of the open fracture.

• Confirm the fracture was initially an open fracture, Type I or II.
• Ensure the documentation clearly states "malunion" and "displaced" for the ulna shaft fracture.
• This code is for subsequent encounters, not the initial treatment of the fracture or the initial diagnosis of malunion.
