Oth physl fx upr end humer, left arm, subs for fx w malunion

This code signifies a fracture of the growth plate (physis) at the upper end of the left humerus, which is not further specified as Salter-Harris types I-IV. The fracture is currently healing with malunion, meaning it has healed or is healing in an anatomically incorrect or misaligned position. This specific encounter is for ongoing treatment of this malunited fracture.

Use this code for follow-up encounters where a patient is receiving care for a previously diagnosed, unspecified physeal fracture of the left proximal humerus that has developed malunion. This applies when the patient is still under active treatment for the malunion, such as monitoring, physical therapy, or planning for corrective surgery. It indicates that the fracture is not yet fully healed without complication.

• Ensure documentation clearly specifies "malunion" and not "nonunion" or "delayed healing," as these have different codes.
• Verify the encounter is for a subsequent visit related to the fracture's healing, not the initial injury or a sequela.
• Confirm the fracture site is the upper end of the left humerus and the physeal involvement is not specified as a Salter-Harris type.
