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

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, the fracture has healed incorrectly, resulting in a malunion. This indicates a prior injury that is now being addressed due to the unsatisfactory healing outcome.

This code is appropriate for follow-up encounters where a patient is being treated for a previously diagnosed comminuted shaft fracture of the left humerus that has healed in an anatomically incorrect position. This could include evaluations for corrective surgery, physical therapy to address functional limitations from the malunion, or ongoing management of pain and disability related to the improperly healed fracture. It is used when the malunion itself is the focus of the current encounter.

• Ensure documentation clearly states "malunion" and specifies the left humerus shaft.
• Verify the fracture was comminuted and displaced at the time of initial injury.
• This "P" seventh character indicates a subsequent encounter for a fracture with malunion, not an initial treatment or routine follow-up for a healing fracture.
