What This Code Means

A condition where rheumatoid arthritis affects multiple joints throughout the body and also causes inflammation in the lungs.

Coding Tips

•This code is used when rheumatoid lung disease occurs with arthritis in three or more joint sites
•Document all affected joint sites to support the multiple sites designation

Clinical Significance

This diagnosis represents the most severe form of rheumatoid arthritis with multiple joint involvement and pulmonary complications, indicating extensive systemic disease with significant functional impairment. This condition requires aggressive immunosuppressive therapy and multidisciplinary management due to widespread joint destruction and extra-articular manifestations.

Documentation Requirements

✓Confirmed rheumatoid arthritis with positive serological testing
✓Documentation of multiple joint involvement with inflammatory findings
✓Evidence of rheumatoid lung disease through appropriate diagnostic studies
✓Clear notation of involvement in multiple anatomical sites
✓Clinical assessment linking lung pathology to rheumatoid etiology
✓Comprehensive functional assessment of multiple affected joints
✓Treatment plan addressing both polyarticular disease and pulmonary management
