Oth spon disrupt of posterior cruciate ligament of left knee

This code signifies a non-traumatic, sudden tear or rupture of the posterior cruciate ligament (PCL) in the left knee. This disruption is not due to an external force or injury, but rather occurs spontaneously, often related to degenerative changes within the ligament.

Apply this code when documentation explicitly states a spontaneous, non-traumatic rupture or tear of the left PCL. Supporting documentation should rule out acute injury and may indicate underlying degenerative changes or pre-existing conditions contributing to the ligament's failure.

• Ensure documentation specifies "spontaneous" or "non-traumatic" to differentiate from acute traumatic tears.
• Verify laterality (left knee) is clearly documented.
• Consider additional codes for any underlying degenerative conditions of the knee if documented.
