0.000What This Code Means
Felty's syndrome affecting the wrist, a condition combining rheumatoid arthritis with an enlarged spleen and low white blood cell count, when the specific wrist is not identified.
Coding Tips
- •Use this code only when documentation does not specify right or left wrist; query provider if laterality is documented elsewhere
- •Felty's syndrome is a rare extra-articular manifestation of rheumatoid arthritis; ensure RA diagnosis is also coded
Clinical Significance
Felty's syndrome with unspecified wrist involvement indicates the presence of the complete diagnostic triad affecting the wrist region without documented laterality. This severe rheumatoid variant requires comprehensive care coordination due to the combination of joint inflammation, splenomegaly, and neutropenia creating multiple clinical challenges.
Documentation Requirements
- ✓Documentation of rheumatoid arthritis affecting wrist without laterality specification
- ✓Clinical or radiologic evidence of splenomegaly
- ✓Laboratory documentation of neutropenia with quantitative values
- ✓Wrist joint involvement noted but side not specified
- ✓Assessment of inflammatory markers and joint function
- ✓Evaluation of immune status and infection history
- ✓Treatment protocol addressing all syndrome components
- ✓Multidisciplinary care coordination documentation
