S42.422P
ICD-10-CMDisplaced comminuted supracondylar fracture without intercondylar fracture of left humerus, subsequent encounter for fracture with malunion
This code signifies a complex break in the lower part of the left upper arm bone, specifically above the elbow joint, where the bone fragments are separated and shattered into multiple pieces. This particular fracture does not extend between the condyles, and the current encounter addresses a complication where the bone has healed in an incorrect or deformed position.
This code is appropriate for follow-up encounters when a patient presents with a previously treated displaced comminuted supracondylar fracture of the left humerus that has healed with a noticeable deformity or angulation. It would be used when the malunion is being evaluated, monitored, or is the focus of further treatment plans, such as corrective osteotomy.
