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

This code signifies a complete displacement of the upper portion of the right shin bone (tibia) from its normal articulation with the thigh bone (femur), specifically occurring on the outer side of the knee joint. This injury typically involves significant ligamentous damage and results in knee instability and pain.

This code is appropriate for documenting the initial treatment of a patient presenting with a newly diagnosed lateral dislocation of the proximal right tibia. This often occurs following high-energy trauma, such as sports injuries or motor vehicle accidents, where a direct blow or twisting force is applied to the knee.

• Ensure documentation specifies "lateral" dislocation and "right knee" to support this specific code.
• Verify that this is the patient's initial encounter for this specific injury; subsequent encounters will require a different seventh character.
• Look for associated documentation of ligamentous tears (e.g., ACL, PCL, collateral ligaments) as these are common with knee dislocations and may require additional coding.
