Sltr-haris Type III physl fx upper end humer, unsp arm, 7thK

This code describes a specific type of growth plate fracture (Salter-Harris Type III) affecting the top part of the humerus, which is the upper arm bone. This particular injury is in the process of healing poorly, meaning the bone fragments have not united after a previous treatment attempt. The fracture location is unspecified regarding left or right arm.

Apply this code when documenting follow-up care for a patient with a previously diagnosed Salter-Harris Type III fracture of the proximal humerus who is now presenting with evidence of nonunion. This would include scenarios where surgical intervention for nonunion is being planned or conservative management for nonunion is ongoing.

• Ensure documentation clearly specifies "nonunion" and a "subsequent encounter" for the fracture.
• Verify the fracture type is explicitly documented as Salter-Harris Type III and located at the upper end of the humerus.
• Do not use this code for initial treatment or for fractures that are healing normally.
