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

This code signifies a severe fracture of the left ulna, specifically a comminuted break in the shaft where the bone is shattered into multiple fragments. The fracture is displaced, meaning the bone ends are not properly aligned, and it is an open fracture, indicating the bone has broken through the skin or there is a deep wound communicating with the fracture site, classified as type IIIA, IIIB, or IIIC.

This code is appropriate for the initial treatment of a patient presenting with a left ulnar shaft fracture that is both comminuted and displaced, and is identified as an open fracture of the specified types. It is used when the patient is receiving active treatment for the fracture, such as surgical repair or casting.

• Ensure documentation clearly specifies "left arm" and "shaft of ulna" to support this code.
• Verify the fracture is explicitly documented as "comminuted" and "displaced" in addition to being an open fracture type IIIA, IIIB, or IIIC.
• Confirm this is the initial encounter for active treatment of the fracture; subsequent encounters will require different seventh characters.
