Unsp physl fx low end humer, l arm, subs for fx w malunion

This code signifies a fracture of the growth plate at the distal end of the left humerus, where the specific type of physeal fracture is not documented. It indicates that the fracture has healed in an imperfect alignment, and the patient is presenting for follow-up care related to this malunion.

Use this code when a patient with a previously treated, unspecified physeal fracture of the lower left humerus presents for evaluation or management of a documented malunion. This applies to subsequent visits after the initial treatment of the fracture, where the malunion is the focus of the encounter.

• Ensure documentation explicitly states "malunion" and specifies the left arm.
• Verify that the encounter is for follow-up care of the malunion, not initial treatment or routine healing.
• Confirm that the specific type of physeal fracture (e.g., Salter-Harris type) was not documented at the time of initial injury.
