What This Code Means

A systemic form of childhood arthritis with fever and rash that specifically affects the left shoulder joint.

Coding Tips

•Use this code when systemic onset juvenile rheumatoid arthritis is documented with left shoulder involvement
•Confirm left-sided involvement is explicitly stated in clinical documentation

Clinical Significance

This diagnosis represents systemic onset juvenile rheumatoid arthritis with specific left shoulder involvement, combining severe systemic inflammatory disease with focal joint destruction. The systemic nature significantly increases morbidity risk and requires aggressive immunosuppressive treatment to prevent life-threatening complications.

Documentation Requirements

✓Physician diagnosis of systemic onset juvenile rheumatoid arthritis
✓Specific documentation of left shoulder joint involvement
✓Age of onset documented as under 16 years
✓Evidence of systemic manifestations (fever, rash, hepatosplenomegaly)
✓Left shoulder functional assessment and range of motion
✓Elevated inflammatory markers and systemic involvement
✓Treatment plan with biologic or targeted therapy
✓Regular monitoring for systemic complications

Commonly Confused Codes

M08211 — Right shoulder involvement instead of left M08219 — Unspecified shoulder when left side documented M08012 — Unspecified JRA left shoulder without systemic features M06.812 — Adult RA left shoulder for patients over 16 M25.512 — Left shoulder pain without inflammatory arthritis
