0.000What This Code Means
A firm lump under the skin on the right elbow caused by rheumatoid arthritis.
Coding Tips
- •The elbow is a common site for rheumatoid nodule formation due to pressure and friction
- •Verify right-sided location is documented before coding this specific laterality
Clinical Significance
Rheumatoid nodule at the right elbow represents a common location for extraarticular RA manifestations, typically occurring at pressure points. This indicates more severe, often seropositive rheumatoid disease with potential functional limitations.
Documentation Requirements
- ✓Confirmed rheumatoid arthritis diagnosis
- ✓Physical examination documenting right elbow nodule
- ✓Specific laterality documentation (right side)
- ✓Nodule characteristics including size and consistency
- ✓Assessment of elbow function and range of motion
- ✓Laboratory evidence of RA (typically RF or anti-CCP positive)
- ✓Documentation of disease severity and activity
- ✓Treatment plan and response to therapy
