Oth physl fx upr end humer, l arm, subs for fx w delay heal

This code signifies a fracture of the growth plate at the top of the left humerus, excluding epiphyseal separations. It indicates that the patient is in a subsequent phase of care for this injury, and the fracture is not healing at the expected rate.

Apply this code when a patient presents for follow-up treatment of a left upper humeral physeal fracture that is demonstrating delayed union. This is appropriate for encounters after the initial treatment, where the fracture has not yet fully consolidated.

• Ensure documentation clearly states "left arm" and "delayed healing" for the physeal fracture.
• Confirm this is a subsequent encounter, not the initial treatment or a sequela.
• Distinguish from Salter-Harris types I-VI if more specific documentation is available, as this code is for "other" physeal fractures.
