Felty's syndrome, right wrist

This code signifies Felty's syndrome affecting the right wrist. Felty's syndrome is a rare, severe complication of rheumatoid arthritis characterized by the triad of rheumatoid arthritis, splenomegaly, and neutropenia. The code specifies the anatomical location of the manifestation.

Use this code when documentation clearly indicates a diagnosis of Felty's syndrome with specific involvement of the right wrist. This typically occurs in patients with long-standing, severe rheumatoid arthritis who present with symptoms related to the wrist joint, such as pain, swelling, or deformity, in addition to systemic signs of Felty's syndrome. Documentation should confirm both the syndrome and the specific joint involvement.

• Always sequence a code for the underlying rheumatoid arthritis (e.g., from category M05 or M06) before this code.
• Ensure documentation explicitly states "Felty's syndrome" and specifies "right wrist" involvement; do not assume laterality.
• Differentiate from other forms of rheumatoid arthritis without the full Felty's syndrome triad.
