S42.264P
ICD-10-CMNondisplaced fracture of lesser tuberosity of right humerus, subsequent encounter for fracture with malunion
This code signifies a fracture of the lesser tuberosity on the right humerus that is not displaced, meaning the bone fragments remain in their normal anatomical alignment. The "subsequent encounter" indicates the patient is receiving follow-up care for this fracture, and "malunion" specifies that the bone has healed, but in an unsatisfactory or deformed position.
This code is appropriate for documenting ongoing treatment for a previously diagnosed nondisplaced lesser tuberosity fracture of the right humerus where imaging or clinical assessment confirms malunion. It would be used for office visits, physical therapy, or other follow-up care related to the malunited fracture.
