What This Code Means

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

Coding Tips

  • Confirm right knee is documented; do not assume from bilateral disease without explicit statement
  • Note that vasculitis in rheumatoid arthritis may indicate more severe systemic disease

Clinical Significance

This diagnosis represents severe rheumatoid disease with systemic vasculitic complications specifically affecting the right knee joint. The condition indicates advanced inflammatory arthropathy with significant functional impact requiring intensive immunosuppressive therapy and comprehensive monitoring for joint preservation and systemic complications.

Documentation Requirements

  • Confirmed rheumatoid arthritis with positive RF or anti-CCP antibodies
  • Clinical or pathological evidence of rheumatoid vasculitis
  • Right knee joint involvement specifically documented
  • Evidence of active systemic inflammation through lab values
  • Assessment of knee joint damage and functional limitations
  • Documentation of other extra-articular manifestations
  • Current treatment with disease-modifying medications
  • Regular monitoring for therapeutic response and adverse effects
