Displ commnt fx shaft of ulna, l arm, 7thP

This code signifies a specific type of left ulna shaft fracture that is both displaced and comminuted, meaning the bone is broken into multiple fragments and out of alignment. The "subsequent encounter" indicates the patient is receiving follow-up care for a fracture that has already been treated, and "malunion" specifies that the bone has healed in an incorrect or deformed position.

Use this code for patients presenting for ongoing management of a previously treated left ulna shaft fracture that has healed improperly. This includes scenarios where the malunion is being assessed, monitored, or is the focus of further intervention (e.g., corrective osteotomy planning). It is appropriate for follow-up visits after initial treatment.

• Ensure documentation clearly specifies "left arm" and "shaft of ulna" to differentiate from other forearm bones or locations.
• Verify the "subsequent encounter" and "malunion" are explicitly documented, as these are key components of this specific code.
• Do not use for initial treatment of the fracture or for nonunion (failure to heal), as those have different code assignments.
