Traumatic arthropathy, right knee

This code signifies degenerative joint disease in the right knee that has developed as a direct consequence of a prior injury or trauma to the joint. It represents a form of osteoarthritis specifically attributed to a traumatic event, rather than primary or idiopathic causes.

Apply this code when documentation clearly states a diagnosis of traumatic arthropathy affecting the right knee. This diagnosis should be supported by a history of significant knee trauma (e.g., fracture, ligamentous injury) preceding the onset of arthritic changes.

• Ensure documentation specifies "traumatic" arthropathy; do not use for primary osteoarthritis.
• Verify the laterality is explicitly stated as "right knee."
• Consider sequencing this code after an acute injury code if the trauma is recent and directly led to the arthropathy.
