What This Code Means

A firm, non-cancerous nodule associated with rheumatoid arthritis that develops in the spine or vertebral column.

Coding Tips

•Vertebral rheumatoid nodules are less common than nodules in other locations; ensure documentation clearly indicates spinal involvement
•Consider whether the nodule is causing spinal cord compression or neurological symptoms, which may require additional coding

Clinical Significance

Rheumatoid nodules affecting the vertebrae represent a severe and uncommon manifestation of rheumatoid arthritis with potential for serious neurological complications. Spinal involvement indicates systemic disease progression and requires specialized monitoring for cord compression or instability.

Documentation Requirements

✓Confirmed rheumatoid arthritis diagnosis with established criteria
✓Imaging studies documenting vertebral nodule presence (CT, MRI)
✓Specific vertebral level identification when possible
✓Neurological examination findings and functional assessment
✓Assessment for spinal stability and cord compression risk
✓Laboratory markers supporting active inflammatory disease
✓Specialist consultation documentation (rheumatology, neurosurgery)
✓Treatment plan addressing both nodular disease and spinal complications
