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

This code signifies a complex break in the main part of the left upper arm bone, where the bone has shattered into multiple fragments and the pieces are no longer aligned. Furthermore, this specific encounter indicates that the fracture has failed to heal properly after an initial treatment attempt.

Apply this code for follow-up visits where a patient is being managed for a previously treated, but now non-united, comminuted fracture of the left humeral shaft. This includes scenarios such as evaluation for revision surgery, ongoing conservative management for nonunion, or assessment of complications related to the nonunion.

• Ensure documentation explicitly states "nonunion" and specifies the left humerus.
• Verify the fracture type is "comminuted" and "displaced" for accurate coding.
• This "K" seventh character indicates a subsequent encounter for a fracture with nonunion; do not use for initial treatment or routine follow-up of a healing fracture.
