Juvenile rheumatoid arthritis w systemic onset, unsp wrist

This code signifies a diagnosis of juvenile idiopathic arthritis (JIA) that presents with systemic features, such as fever, rash, and lymphadenopathy, and affects an unspecified wrist joint. This is a chronic inflammatory condition primarily affecting children under 16 years of age.

Use this code when the medical record clearly documents a diagnosis of systemic onset JIA with involvement of a wrist, but the specific laterality (left or right) is not specified. Documentation should include evidence of systemic symptoms alongside arthritic manifestations in the wrist.

• Ensure documentation specifies "systemic onset" to differentiate from other JIA subtypes.
• Avoid using this code if the laterality of the affected wrist is documented; instead, use the more specific codes for left or right wrist involvement.
• Consider sequencing this code as the primary diagnosis if it is the main reason for the encounter.
