S42.422B
ICD-10-CMDisplaced comminuted supracondylar fracture without intercondylar fracture of left humerus, initial encounter for open fracture
This code describes a severe fracture of the lower part of the left upper arm bone (humerus) that is broken into multiple pieces (comminuted) and has shifted out of alignment (displaced). The fracture is located above the elbow joint (supracondylar) but does not extend into the joint itself (without intercondylar fracture). This specific code indicates an open fracture, meaning the bone has broken through the skin or there is a wound communicating with the fracture site, and it is the initial treatment for this injury.
Use this code for a patient presenting with a newly diagnosed, open, comminuted, and displaced supracondylar fracture of the left humerus that does not involve the intercondylar region. This applies to the initial surgical or non-surgical management of the fracture. It would be appropriate for emergency department visits, initial orthopedic consultations, or the first hospitalization for this specific injury.
