S42.409A
ICD-10-CMUnspecified fracture of lower end of unspecified humerus, initial encounter for closed fracture
This code signifies a fracture affecting the distal portion of the humerus, the long bone of the upper arm, where the specific type of fracture (e.g., supracondylar, intercondylar) is not documented. It indicates that the skin over the fracture site is intact (closed fracture) and this is the initial treatment encounter for the injury.
Use this code when documentation confirms a fracture of the lower end of the humerus but lacks specificity regarding the exact anatomical location or type of fracture. This is appropriate for the initial visit where the fracture is being diagnosed and treated, and there is no open wound associated with the injury.
