0.000What This Code Means
Felty's syndrome affecting the left wrist, characterized by rheumatoid arthritis, enlarged spleen, and low white blood cell count.
Coding Tips
- •Ensure documentation clearly specifies left wrist as the affected site
- •Verify this is not bilateral or right wrist involvement before assigning this code
Clinical Significance
Felty's syndrome involving the left wrist represents a severe rheumatoid condition that creates significant functional impairment combined with dangerous immunosuppression. This diagnosis requires urgent multidisciplinary intervention due to the combination of joint destruction, neutropenia-induced infection risk, and systemic inflammatory complications.
Documentation Requirements
- ✓Clear documentation of rheumatoid arthritis specifically affecting the left wrist
- ✓Evidence of splenomegaly through physical examination or imaging
- ✓Laboratory confirmation of neutropenia with specific white blood cell counts
- ✓Left wrist laterality explicitly documented
- ✓Assessment of wrist joint function and range of motion
- ✓History of infections or immune dysfunction
- ✓Current immunosuppressive therapy and monitoring schedule
- ✓Coordinated care plan addressing rheumatologic and hematologic aspects
