Juvenile rheumatoid arthritis with systemic onset, left hip

This code describes a specific type of chronic inflammatory arthritis affecting children, characterized by systemic symptoms like fever, rash, and lymphadenopathy, in addition to joint involvement. Specifically, it indicates that the left hip joint is affected by this systemic onset juvenile idiopathic arthritis.

Use this code when documentation clearly states a diagnosis of juvenile rheumatoid arthritis (JRA) or juvenile idiopathic arthritis (JIA) with systemic onset, and explicitly identifies the left hip as an affected joint. This diagnosis is typically made by a rheumatologist based on clinical criteria and exclusion of other conditions.

• Ensure documentation specifies "systemic onset" and laterality of the hip involvement.
• Do not confuse with other types of JIA (e.g., oligoarticular, polyarticular) which have different code assignments.
• Code any associated systemic manifestations (e.g., fever, rash) separately if they are significant and documented.
