S42.415P
ICD-10-CMNondisplaced simple supracondylar fracture without intercondylar fracture of left humerus, subsequent encounter for fracture with malunion
This code describes a left humerus fracture located above the condyles, which are the rounded prominences at the end of the bone forming part of the elbow joint. The fracture is simple, meaning it has a single fracture line, and is nondisplaced, indicating the bone fragments are still in their normal anatomical alignment. This specific code is used when the fracture has healed incorrectly, resulting in a malunion, and the patient is receiving follow-up care for this complication.
Use this code for a patient presenting for follow-up treatment or evaluation of a previously sustained nondisplaced simple supracondylar fracture of the left humerus that has healed in an unsatisfactory position (malunion). This applies when the malunion itself is the focus of the current encounter, such as for assessment of range of motion limitations, pain, or planning for corrective surgery.
