Juvenile rheumatoid arthritis w systemic onset, right elbow

This code signifies a chronic inflammatory autoimmune disease affecting the right elbow joint in a pediatric patient, characterized by systemic features such as fever, rash, and lymphadenopathy, in addition to arthritis. It represents a specific subtype of juvenile idiopathic arthritis (JIA) with a distinct clinical presentation.

Apply this code when documentation clearly indicates a diagnosis of juvenile rheumatoid arthritis with systemic onset, specifically affecting the right elbow. Supporting documentation should detail the systemic manifestations alongside the arthritis in the specified joint.

• Ensure the documentation explicitly states "systemic onset" to differentiate from other JIA subtypes.
• Verify laterality (right elbow) is clearly documented; separate codes exist for left or bilateral involvement.
• Do not confuse with adult rheumatoid arthritis codes, as this is a pediatric condition.
