Oth physl fx low end humer, unsp arm, subs for fx w nonunion

This code describes a fracture involving the growth plate (physis) at the lower end of the humerus, where the specific type of physeal fracture is not further specified. It indicates that the fracture is located in an unspecified arm and that the bone fragments have failed to heal together properly (nonunion) during a subsequent encounter for treatment.

Use this code for follow-up encounters when a patient presents with a previously diagnosed, unspecified physeal fracture of the distal humerus, and imaging or clinical assessment confirms that the fracture has not united. This applies when the laterality (left or right arm) was not documented or is unknown.

• Ensure documentation clearly states "nonunion" for a subsequent encounter.
• Verify that the fracture is indeed physeal and at the lower end of the humerus.
• Only use the "unspecified arm" designation when laterality is genuinely unstated in the medical record.
