ICD-10-CMDisplaced fracture of lateral condyle of unspecified humerus, subsequent encounter for fracture with nonunion
This code signifies a fracture of the outer bony prominence of the upper arm bone (humerus) that has shifted out of alignment. Importantly, the fracture has failed to heal properly and is currently being treated for this nonunion, and the specific arm (left or right) is not documented.
This code is appropriate for follow-up encounters where a patient is receiving ongoing treatment for a lateral condyle fracture of the humerus that has not united. This includes situations where surgical intervention, casting, or other therapies are being provided to address the nonunion. It is used when the laterality of the humerus is not specified in the medical record.
