Juvenile rheumatoid arthritis with systemic onset, left hand

This code identifies a specific type of juvenile idiopathic arthritis (JIA) characterized by systemic symptoms like fever, rash, and lymphadenopathy, affecting the left hand. It signifies the presence of chronic inflammatory arthritis in a pediatric patient with systemic onset features.

Use this code when documentation clearly indicates a diagnosis of juvenile rheumatoid arthritis (now termed systemic JIA) with systemic manifestations and involvement of the left hand. Supporting documentation should include physician notes detailing the systemic symptoms, joint involvement, and diagnostic criteria for systemic JIA.

• Ensure the documentation specifies "systemic onset" and not another JIA subtype.
• Laterality is crucial; confirm the left hand is explicitly documented as affected.
• Do not confuse with other forms of JIA that do not have systemic onset features.
