Felty's syndrome, unspecified wrist

This code identifies Felty's syndrome, a severe and rare complication of rheumatoid arthritis characterized by the triad of seropositive rheumatoid arthritis, splenomegaly, and neutropenia. It specifically indicates that the wrist joint is affected, but the laterality (left or right) is not specified in the medical record.

Use this code when documentation confirms a diagnosis of Felty's syndrome and explicitly mentions wrist involvement without specifying which wrist. Supporting documentation would include physician notes detailing the diagnostic criteria for Felty's syndrome (RA, splenomegaly, neutropenia) and clinical findings or imaging reports indicating arthritis in the wrist.

• Always strive for greater specificity regarding laterality (left, right, bilateral) if documented.
• Code the underlying rheumatoid arthritis (e.g., M05.xx) as the primary diagnosis if Felty's syndrome is considered a manifestation or complication.
• Ensure documentation clearly distinguishes Felty's syndrome from other forms of rheumatoid arthritis or other causes of splenomegaly and neutropenia.
