Sltr-haris Type I physl fx low end l fibula, 7thK

This code signifies a growth plate fracture at the lower end of the left fibula, specifically a Salter-Harris Type I injury, which involves a separation of the epiphysis from the metaphysis without bone fracture. The "subsequent encounter" indicates ongoing treatment for this fracture, and the "nonunion" specifies that the bone fragments have failed to heal together after a reasonable period.

Use this code for follow-up visits or ongoing care for a patient who previously sustained a Salter-Harris Type I fracture of the distal left fibula and is now experiencing complications due to the fracture not healing properly. This would apply to situations where further interventions, such as surgical revision or extended immobilization, are being considered or performed due to the nonunion.

• Ensure documentation clearly specifies "nonunion" for the fracture.
• Verify the laterality (left fibula) and the specific Salter-Harris type (Type I).
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
