S42.421P
ICD-10-CMDisplaced comminuted supracondylar fracture without intercondylar fracture of right humerus, subsequent encounter for fracture with malunion
This code describes a complex fracture of the right humerus, specifically above the elbow joint, where the bone has broken into multiple fragments and the pieces are not properly aligned. It also indicates that the fracture is in a healing stage where it has united in an undesirable position, leading to functional impairment.
Use this code when documenting follow-up care for a patient whose right supracondylar humerus fracture, initially comminuted and displaced, has healed with malunion. This would apply during clinic visits, physical therapy, or surgical evaluations addressing the consequences of the malunion.
