S03.42XS
ICD-10-CMThis code signifies a chronic or late effect of a sprain affecting the temporomandibular joint (TMJ) on the left side. It indicates that the initial injury has resolved, but the patient continues to experience residual symptoms or complications directly attributable to that past sprain.
Apply this code when documentation clearly indicates a history of a left jaw sprain and the patient presents with ongoing issues such as chronic pain, limited range of motion, or recurrent instability directly linked to that prior injury. The medical record must specify the left side and confirm the sequela nature of the current condition.
