Felty's syndrome, right hand

This code signifies Felty's syndrome affecting the right hand. Felty's syndrome is a rare, severe form of rheumatoid arthritis characterized by the triad of seropositive rheumatoid arthritis, splenomegaly, and neutropenia. The condition often leads to joint destruction, particularly in the small joints of the hands and feet.

Use this code when documentation explicitly states a diagnosis of Felty's syndrome with involvement of the right hand. This typically applies to patients presenting with chronic rheumatoid arthritis, palpable splenomegaly, and laboratory confirmed neutropenia, with specific symptoms or findings localized to the right hand.

• Ensure documentation specifies "Felty's syndrome" and not just general rheumatoid arthritis, as Felty's is a distinct, more severe variant.
• Verify the laterality (right hand) is clearly documented. If bilateral or unspecified, a different code would be appropriate.
• Code any associated manifestations of Felty's syndrome, such as neutropenia (D70.0) or splenomegaly (R16.1), as secondary diagnoses.
