What This Code Means

A type of childhood arthritis affecting the hand with systemic symptoms when the specific side (left or right) is not documented or both sides are involved.

Coding Tips

•Use this code only when hand laterality is not specified in documentation
•Request clarification from provider regarding which hand(s) are affected for more precise coding

Clinical Significance

Juvenile rheumatoid arthritis with systemic onset represents a severe form of childhood arthritis with significant systemic inflammation requiring intensive management. This diagnosis indicates high healthcare resource utilization with potential for serious complications including growth retardation, joint destruction, and multi-organ involvement.

Documentation Requirements

✓Patient age at onset (must be under 16 years)
✓Evidence of systemic symptoms (fever, rash, lymphadenopathy, hepatosplenomegaly)
✓Documentation of hand joint involvement without laterality specification or bilateral involvement
✓Laboratory evidence of systemic inflammation (elevated ESR, CRP)
✓Exclusion of other causes of arthritis and systemic illness
✓Duration of symptoms (minimum 6 weeks for JRA diagnosis)
✓Physical examination findings of joint swelling, warmth, or limited range of motion
✓Assessment of functional impact on activities of daily living
