Sprain of posterior cruciate ligament of right knee, init

This code signifies a tear or overstretching of the posterior cruciate ligament (PCL) in the right knee. The PCL is a major ligament that prevents the tibia from sliding backward under the femur. This injury typically results from a direct blow to the front of the knee or a hyperextension injury.

Apply this code when documenting an initial encounter for a sprain of the right knee's posterior cruciate ligament. This includes cases where the patient is first presenting for diagnosis and treatment of the injury. It is appropriate for both acute and subacute presentations of a newly diagnosed PCL sprain.

• Ensure laterality is correctly identified as "right" for the knee.
• Confirm this is the patient's initial encounter for this specific injury.
• Distinguish from other knee ligament sprains (e.g., ACL, MCL, LCL) to ensure accurate coding.
