Displ seg fx shaft of humer, unsp arm, 7thK

This code signifies a specific type of humerus fracture where the bone is broken into three or more pieces (segmental) and the broken ends are not aligned (displaced). It applies to cases where the fracture is located in the shaft of the humerus, the arm involved is not specified, and the patient is receiving follow-up care for a fracture that has failed to heal properly (nonunion).

Use this code for a patient presenting for ongoing management of a previously diagnosed segmental, displaced humeral shaft fracture that has developed nonunion. This would include scenarios such as follow-up appointments for non-operative management of nonunion, or pre-operative evaluations for surgical intervention to address the nonunion.

• Ensure documentation clearly states "nonunion" as the reason for the subsequent encounter.
• Confirm the fracture is described as "segmental" and "displaced" in the humerus shaft.
• Only use this code when the laterality (left or right arm) is not specified in the medical record.
