S42.421B
ICD-10-CMDisplaced comminuted supracondylar fracture without intercondylar fracture of right humerus, initial encounter for open fracture
This code describes a severe fracture of the right humerus, specifically above the condyles, where the bone is broken into multiple fragments and the broken ends are not properly aligned. It also specifies that the fracture does not extend between the condyles.
This code is appropriate for initial treatment of a patient presenting with an open fracture of the right humerus, located just above the elbow joint, that is both comminuted and displaced. This typically involves trauma resulting in bone fragments protruding through the skin or a wound communicating with the fracture site.
