Felty's syndrome, left wrist

This code signifies Felty's syndrome affecting the left wrist. Felty's syndrome is a rare, severe form of rheumatoid arthritis characterized by the triad of rheumatoid arthritis, splenomegaly, and neutropenia. The "32" in the code specifies the left wrist as the anatomical site of involvement.

Use this code when documentation explicitly states a diagnosis of Felty's syndrome with involvement of the left wrist. This typically occurs in patients with long-standing, aggressive rheumatoid arthritis who develop systemic manifestations including an enlarged spleen and low neutrophil count, with specific mention of left wrist symptoms or findings.

• Ensure documentation clearly links Felty's syndrome to the left wrist.
• Do not use this code for general rheumatoid arthritis without the specific diagnosis of Felty's syndrome.
• Always code the underlying rheumatoid arthritis (e.g., M05.00) if not already included in the Felty's syndrome code, and any associated neutropenia (D70.0) or splenomegaly (R16.1) if separately documented and not inherent to the Felty's syndrome code.
