Juvenile rheumatoid arthritis w systemic onset, right wrist

This code signifies a diagnosis of juvenile idiopathic arthritis (JIA) of the systemic onset subtype, specifically affecting the right wrist. Systemic JIA is characterized by arthritis accompanied by fever, rash, lymphadenopathy, hepatosplenomegaly, and serositis.

Apply this code when documentation clearly indicates a diagnosis of systemic onset JIA with active inflammation or involvement of the right wrist joint. Supporting documentation should include a physician's diagnosis of systemic JIA and specific mention of right wrist involvement.

• Ensure the documentation specifies "systemic onset" JIA, as other JIA subtypes have different codes.
• Verify the laterality (right wrist) is explicitly stated; codes exist for left, bilateral, and unspecified wrist involvement.
• Do not confuse with other forms of juvenile arthritis, such as oligoarticular or polyarticular JIA, which are coded differently.
