S42.423A
ICD-10-CMDisplaced comminuted supracondylar fracture without intercondylar fracture of unspecified humerus, initial encounter for closed fracture
This code signifies a complex fracture of the humerus, specifically above the elbow joint, where the bone is broken into multiple fragments and the pieces are no longer in their normal alignment. Importantly, the fracture does not extend into the joint surface between the humerus and the forearm bones.
This code is appropriate for the initial treatment of a newly diagnosed comminuted supracondylar fracture of the humerus that is displaced and does not involve the intercondylar region. It is used when the laterality (left or right arm) is not documented or is unknown at the time of coding.
