S42.022S
ICD-10-CMThis code signifies a malunion or nonunion of a previously fractured left clavicular shaft that has resulted in a displaced bone fragment. It indicates a chronic or long-term complication of the initial fracture, where the bone has not healed correctly and remains out of alignment. The displacement can lead to ongoing pain, functional impairment, and cosmetic deformity.
Apply this code for patients presenting with persistent symptoms related to a prior left clavicle shaft fracture where imaging confirms a displaced fragment and the fracture is no longer acute. This is appropriate for follow-up encounters addressing complications of the initial injury, such as pain, limited range of motion, or nerve impingement due to the uncorrected displacement. It should be used when the patient is beyond the initial healing phase.
