Secondary osteoarthritis, right shoulder

This code identifies degenerative joint disease of the right shoulder that develops as a consequence of another underlying condition, such as trauma, infection, or a congenital deformity. It signifies articular cartilage breakdown and associated bone changes in the glenohumeral joint, specifically affecting the right side, that is not primary (idiopathic) in origin.

Apply this code when documentation clearly indicates osteoarthritis of the right shoulder attributed to a secondary cause. This includes cases where a previous injury, inflammatory arthropathy, or metabolic disorder has led to the development of shoulder arthritis. Supporting documentation should specify the laterality and the secondary nature of the osteoarthritis.

• Always sequence the underlying cause of the secondary osteoarthritis first, if known and actively treated.
• Distinguish carefully between primary (idiopathic) and secondary osteoarthritis; documentation must explicitly state "secondary" or provide a clear causal link.
• Ensure laterality is accurately documented as "right shoulder" to avoid miscoding.
