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

This code describes a left humerus shaft fracture, specifically a transverse break that is no longer in its proper alignment. The patient is in a subsequent phase of care, and the fracture has healed incorrectly, resulting in a malunion.

Apply this code when documenting follow-up care for a patient whose left humeral shaft fracture, initially transverse and displaced, has healed in an anatomically incorrect position. This is appropriate for encounters where the malunion is being assessed, monitored, or treated.

• Ensure documentation clearly specifies "left" arm and "transverse" fracture type.
• Verify the encounter is for a "subsequent" phase of care and that "malunion" is explicitly documented.
• Do not use for initial treatment or for nonunion; a malunion implies some degree of healing has occurred, albeit incorrectly.
