What This Code Means

A type of childhood arthritis that affects the right wrist and causes inflammation throughout the body, including fever and rash.

Coding Tips

•Verify laterality is documented as right wrist in the medical record before assigning this code
•Ensure systemic onset is confirmed; if only joint involvement without systemic features, use different M08 subcategory
