S42.321P
ICD-10-CMDisplaced transverse fracture of shaft of humerus, right arm, subsequent encounter for fracture with malunion
This code signifies a right humerus shaft fracture that has healed improperly, resulting in a malunion. The fracture was displaced, meaning the bone fragments were not in their normal alignment, and it specifically affects the transverse plane of the humeral shaft.
This code is appropriate for encounters where a patient is being treated for complications arising from a previously sustained, displaced transverse fracture of the right humeral shaft that has healed in an unsatisfactory position. This includes follow-up visits, evaluations for corrective surgery, or management of ongoing symptoms related to the malunion.
