Sltr-haris Type IV physl fx upr end unsp tibia, 7thK

This code signifies a complex growth plate fracture (Salter-Harris Type IV) affecting the upper part of the shin bone (tibia) in an unspecified location. The "subsequent encounter" indicates that the patient is receiving ongoing care for this fracture, and "nonunion" means the bone fragments have failed to heal together after a typical healing period.

Use this code for follow-up visits, cast changes, or surgical interventions related to a previously diagnosed Salter-Harris Type IV fracture of the proximal tibia that has not healed. This code is appropriate when the physician explicitly documents nonunion of the fracture.

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