Pauciarticular juvenile rheumatoid arthritis, right wrist

This code signifies a chronic inflammatory joint disease affecting four or fewer joints in a child, specifically localized to the right wrist. It is a subtype of juvenile idiopathic arthritis (JIA) characterized by persistent synovitis.

Apply this code when documentation confirms a diagnosis of pauciarticular juvenile rheumatoid arthritis affecting only the right wrist. Supporting clinical notes should detail the onset before age 16, duration of at least six weeks, and involvement of four or fewer joints, with the right wrist being the affected site.

• Ensure the documentation explicitly states "pauciarticular" or "oligoarticular" and clearly identifies the right wrist as the affected joint.
• Do not use this code if more than four joints are involved; consider polyarticular JIA codes instead.
• Verify laterality (right vs. left) is precisely documented for the affected wrist.
