Traumatic arthropathy, left knee

This code signifies a degenerative joint disease of the left knee that has developed as a direct consequence of a previous injury or trauma. It represents a chronic condition where the joint cartilage has been damaged, leading to pain, stiffness, and reduced function, specifically in the left knee.

Use this code when documentation clearly states a diagnosis of traumatic arthropathy affecting the left knee. This typically applies to patients with a history of significant knee injury (e.g., fracture, ligament tear) followed by the gradual onset of arthritic symptoms in that same joint.

• Ensure the documentation explicitly links the arthropathy to a prior trauma; otherwise, a primary osteoarthritis code may be more appropriate.
• Verify laterality; this code is specific to the left knee.
• Look for supporting documentation of the initial trauma and subsequent development of degenerative changes.
