Unsp physl fx upper end humer, r arm, subs for fx w nonunion

This code indicates a fracture of the growth plate at the top of the right humerus, where the specific type of physeal fracture is not documented. It signifies that the patient is receiving follow-up care for this fracture, and the bone has failed to heal properly, resulting in a nonunion.

Apply this code when a patient presents for ongoing treatment of an unhealed, unspecified physeal fracture of the right proximal humerus. This is appropriate for subsequent encounters where nonunion has been confirmed, such as during follow-up appointments for casting changes, physical therapy, or surgical planning for the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the right arm.
• Confirm this is a subsequent encounter, not the initial treatment.
• Do not use if the specific Salter-Harris type of physeal fracture is known.
