Felty's syndrome, left hip

This code indicates Felty's syndrome affecting the left hip. Felty's syndrome is a severe, rare complication of rheumatoid arthritis characterized by the triad of rheumatoid arthritis, splenomegaly, and neutropenia. The specific joint involvement in this case is the left hip.

Use this code when documentation clearly states a diagnosis of Felty's syndrome with specific involvement of the left hip joint. This code is appropriate when the patient presents with symptoms related to Felty's syndrome and the left hip is identified as an affected site. Supporting documentation should include physician notes detailing the diagnosis and the specific joint involvement.

• Always ensure the laterality (left) is clearly documented for the hip involvement.
• Do not confuse this with other forms of rheumatoid arthritis without the specific features of Felty's syndrome.
• Code any associated manifestations of Felty's syndrome (e.g., neutropenia, splenomegaly) with additional codes as appropriate.
