S42.253P
ICD-10-CMDisplaced fracture of greater tuberosity of unspecified humerus, subsequent encounter for fracture with malunion
This code signifies a previously treated fracture of the greater tuberosity of the humerus, where the bone fragments have healed in an abnormal alignment. This malunion can lead to persistent pain, limited range of motion, and functional impairment of the shoulder. The specific humerus (left or right) is not documented.
This code is appropriate for follow-up encounters where a patient presents with complications from a prior greater tuberosity fracture that has healed incorrectly. It should be used when the malunion is confirmed and is the focus of the current treatment or evaluation. This includes scenarios where surgical correction of the malunion is being planned or evaluated.
