Felty's syndrome affecting the hand when the specific hand (right or left) is not identified.
Coding Tips
Clinical Significance
Felty's syndrome with unspecified hand involvement represents the complete triad of rheumatoid arthritis, splenomegaly, and neutropenia affecting hand function without documented laterality. This condition creates severe functional limitations combined with dangerous immunosuppression requiring comprehensive interdisciplinary management approaches.
Documentation Requirements
- ✓Documentation of rheumatoid arthritis affecting hand without laterality specification
- ✓Evidence of splenomegaly through physical examination or imaging
- ✓Laboratory confirmation of neutropenia with specific values
- ✓Hand involvement documented but laterality not specified
- ✓Assessment of hand function and activities of daily living impact
- ✓History of infections or immune dysfunction
- ✓Current treatment plan addressing all syndrome components
- ✓Functional assessment and rehabilitation needs documentation
