Tear of articular cartilage of left knee, current, init

This diagnosis code signifies a recent injury involving a tear of the cartilage that lines the joint surfaces within the left knee. This type of injury often results from acute trauma, twisting motions, or sudden impacts, leading to pain, swelling, and mechanical symptoms in the knee.

Apply this code when documentation clearly indicates a tear of the articular cartilage in the left knee, and the patient is receiving initial active treatment for this specific injury. This includes initial evaluations, diagnostic imaging, and planning for surgical or non-surgical interventions.

• Ensure the documentation specifies "articular cartilage" and not meniscal cartilage, as these are distinct codes.
• Verify the laterality is clearly documented as "left knee."
• The "A" seventh character indicates an initial encounter for active treatment of the injury.
