ICD-10-CMAnterior displaced fracture of sternal end of right clavicle, subsequent encounter for fracture with nonunion
This code signifies a fracture of the anterior aspect of the sternal (medial) end of the right clavicle that has shifted out of its normal anatomical position. Importantly, this specific code indicates that the fracture has failed to heal properly and the patient is presenting for ongoing treatment of this nonunion.
Use this code for follow-up encounters where a patient is receiving care for a previously diagnosed anteriorly displaced fracture of the sternal end of the right clavicle that has not united. This includes situations such as surgical intervention for nonunion, cast changes, or evaluation of nonunion progression.
