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

This code signifies a left arm injury involving a specific type of ulna fracture: a comminuted fracture of the shaft, meaning the bone is broken into multiple pieces. The fracture is also displaced, indicating the bone fragments are not in their normal alignment. This particular code is for a subsequent encounter where the fracture is being treated non-surgically (closed treatment) but has not healed as expected (nonunion).

Use this code for follow-up visits or hospitalizations for a patient with a previously diagnosed left ulna shaft fracture that was comminuted and displaced, and is now being managed conservatively but is demonstrating nonunion. This applies when the physician documents the fracture as closed and specifically notes nonunion during a subsequent encounter.

• Ensure documentation clearly specifies "left arm" and "ulna shaft."
• Verify the fracture type is "comminuted" and "displaced."
• Confirm the encounter is "subsequent" for "closed fracture with nonunion."
