Anterior sublux of proximal end of tibia, left knee, init

This code signifies a partial dislocation of the shin bone (tibia) at the knee joint, specifically where the tibia has shifted forward relative to the thigh bone (femur). This injury affects the left knee and is considered an acute, new presentation.

Use this code for a patient presenting with a newly diagnosed anterior subluxation of the proximal tibia in the left knee, typically following a traumatic event such as a fall, sports injury, or motor vehicle accident. This code is appropriate for the initial evaluation and treatment of the injury.

• Ensure documentation clearly specifies "anterior" subluxation and the "left" knee.
• The "A" in the seventh character indicates an initial encounter for active treatment of the injury.
• Confirm the injury is a subluxation (partial dislocation) and not a complete dislocation.
