What This Code Means

A condition where blood vessel inflammation occurs alongside rheumatoid arthritis affecting the left knee joint.

Coding Tips

•Verify left knee is specifically documented in the medical record
•Consider whether patient has bilateral knee involvement requiring separate coding

Clinical Significance

Indicates severe systemic rheumatoid disease with vasculitic complications involving the left knee joint. This represents advanced inflammatory arthropathy with high morbidity risk requiring aggressive immunosuppressive treatment and comprehensive care management for both articular and extra-articular manifestations.

Documentation Requirements

✓Laboratory-confirmed rheumatoid arthritis diagnosis
✓Evidence of rheumatoid vasculitis through clinical or histological findings
✓Left knee joint involvement clearly specified
✓Active inflammatory process with supporting laboratory evidence
✓Assessment of knee joint function and structural damage
✓Documentation of systemic disease manifestations
✓Current immunosuppressive medication regimen
✓Regular monitoring for disease progression and treatment efficacy
