Acquired absence of left knee

This code indicates a patient's left knee is missing due to a cause other than a congenital condition. It signifies an amputation or surgical removal of the knee joint and surrounding structures on the left side, or a traumatic loss of the left knee.

Use this code for patients who have undergone a left knee disarticulation or a transfemoral amputation where the knee joint is no longer present. It is appropriate for documenting the sequelae of trauma, disease, or surgical intervention resulting in the absence of the left knee.

• Always specify laterality; ensure "left" is accurate.
• Do not use for congenital absence; refer to Q-codes for those cases.
• Code any underlying cause of the amputation (e.g., diabetes, trauma) in addition to this code.
