Sltr-haris Type IV physl fx low end humer, unsp arm, 7thK

This code signifies a specific type of growth plate fracture (Salter-Harris Type IV) affecting the lower part of the humerus in an unspecified arm. The "subsequent encounter" indicates the patient is receiving follow-up care for this fracture, and the "nonunion" specifies that the bone fragments have failed to heal together.

Apply this code when documenting ongoing treatment for a Salter-Harris Type IV fracture of the distal humerus that has not healed properly. This would include visits for assessment of nonunion, planning for revision surgery, or continued conservative management of the unhealed fracture.

• Ensure documentation clearly states "nonunion" and "subsequent encounter" for this specific fracture type.
• Verify the fracture location is the lower end of the humerus.
• Do not use for initial fracture treatment or for fractures that have healed.
