Sprain of posterior cruciate ligament of left knee, init

This code signifies an injury to the posterior cruciate ligament (PCL) in the left knee, specifically a sprain, indicating a stretch or tear of the ligament fibers. The PCL is a critical stabilizer of the knee, preventing the tibia from shifting too far backward relative to the femur.

Apply this code when documentation confirms a PCL sprain of the left knee, such as from a direct blow to the front of the tibia while the knee is flexed (e.g., dashboard injury). This code is appropriate for the initial evaluation and treatment of the injury.

• Ensure the documentation specifies "sprain" and not a complete "tear" or "rupture," which would require a different code.
• Verify the laterality is clearly documented as "left knee."
• The "A" suffix indicates an initial encounter for this condition, meaning the patient is receiving active treatment for the injury.
