S42.435P
ICD-10-CMNondisplaced fracture (avulsion) of lateral epicondyle of left humerus, subsequent encounter for fracture with malunion
This code signifies a previously treated avulsion fracture of the lateral epicondyle on the left humerus, where the bone fragments have healed in an unsatisfactory or deformed position. This malunion indicates a complication in the healing process, potentially leading to functional impairment or pain.
This code is appropriate for follow-up encounters where a patient is being managed for a left humeral lateral epicondyle avulsion fracture that has healed incorrectly. It should be used when the malunion is the primary reason for the current visit, such as for evaluation of ongoing symptoms, planning for corrective surgery, or physical therapy addressing the malunion.
