Felty's syndrome, right hip

This code identifies Felty's syndrome, a rare and severe manifestation of rheumatoid arthritis characterized by the triad of seropositive rheumatoid arthritis, splenomegaly, and neutropenia. This specific code indicates the involvement of the right hip joint. Patients typically present with chronic, erosive polyarthritis, recurrent infections due to neutropenia, and an enlarged spleen.

Use this code when documentation explicitly states a diagnosis of Felty's syndrome with involvement of the right hip. Supporting clinical findings should include evidence of rheumatoid arthritis, splenomegaly confirmed by imaging, and persistent neutropenia on laboratory reports. This code is appropriate when the right hip is identified as an affected joint in the context of Felty's syndrome.

• Ensure documentation clearly specifies "Felty's syndrome" and not just severe rheumatoid arthritis.
• Verify the laterality of hip involvement; separate codes exist for left hip, bilateral, and unspecified.
• Code any associated manifestations or complications of Felty's syndrome, such as recurrent infections (e.g., pneumonia, skin infections), as additional diagnoses.
