S42.423S
ICD-10-CMDisplaced comminuted supracondylar fracture without intercondylar fracture of unspecified humerus, sequela
This code describes a past injury involving a complex fracture of the humerus, specifically above the elbow joint, that was displaced and broke into multiple pieces, but did not extend between the condyles. The "sequela" designation indicates that this code is used to report a current condition or complication resulting from this old fracture, rather than the acute injury itself.
Use this code when a patient presents with a long-term complication or residual effect directly attributable to a previously sustained displaced comminuted supracondylar fracture of the humerus (without intercondylar involvement). Examples include chronic pain, limited range of motion, nonunion, malunion, or nerve damage that developed as a consequence of the original fracture.
