Unspecified juvenile rheumatoid arthritis, multiple sites

This code signifies a chronic inflammatory autoimmune disease affecting multiple joints in individuals under 16 years of age, where the specific subtype of juvenile idiopathic arthritis (JIA) has not been determined. It involves persistent joint pain, swelling, and stiffness, often leading to functional impairment.

Use this code when documentation clearly indicates juvenile rheumatoid arthritis affecting multiple joints, but the specific JIA category (e.g., oligoarticular, polyarticular, systemic) is not specified by the provider. This code is appropriate for initial diagnoses or when further diagnostic workup is pending.

• Avoid using this code if a more specific type of juvenile idiopathic arthritis is documented; always code to the highest level of specificity.
• Ensure the patient's age at onset is clearly documented as under 16 years to support the "juvenile" aspect.
• Consider sequencing this code as the primary diagnosis when it is the reason for the encounter, followed by any associated manifestations or complications.
