Pauciarticular juvenile rheumatoid arthritis, right hip

This code signifies a chronic inflammatory joint disease affecting four or fewer joints, specifically impacting the right hip in a pediatric patient. It is a subtype of juvenile idiopathic arthritis, characterized by persistent synovitis.

Apply this code when documentation explicitly states pauciarticular juvenile rheumatoid arthritis affecting the right hip. This diagnosis is typically made in patients under 16 years old with arthritis lasting at least six weeks.

• Ensure the documentation specifies "pauciarticular" and clearly identifies the "right hip" as the affected joint.
• Distinguish from polyarticular forms of juvenile rheumatoid arthritis, which involve five or more joints.
• Verify the patient's age to confirm eligibility for a juvenile arthritis diagnosis.
