Lateral disloc of proximal end of tibia, left knee, init

This code signifies a complete displacement of the upper portion of the left shin bone (tibia) from its normal articulation with the thigh bone (femur), specifically in a lateral direction. This type of injury involves the knee joint and typically results from significant trauma.

Apply this code when documentation clearly indicates a left knee injury involving a lateral dislocation of the proximal tibia. This code is appropriate for the initial visit or encounter where the injury is first diagnosed and/or treated.

• Ensure the documentation specifies "lateral" displacement and "proximal end of tibia" for the left knee.
• Confirm this is the initial encounter for the injury; subsequent encounters will require a different seventh character.
• Always review imaging reports and physician notes to verify the exact nature and location of the dislocation.
