Chronic postrheumatic arthropathy [Jaccoud], right hand

This code signifies a chronic joint disease affecting the right hand, specifically characterized by deformities and functional limitations that develop following an episode of rheumatic fever. It describes a non-erosive arthropathy, often presenting with ulnar deviation of the fingers and metacarpophalangeal joint subluxation, without significant bone or cartilage destruction.

Apply this code when documentation clearly indicates a diagnosis of Jaccoud's arthropathy in the right hand, confirmed to be a sequela of rheumatic fever. This diagnosis is typically supported by a history of rheumatic fever, characteristic hand deformities, and imaging studies ruling out other causes of arthropathy.

• Ensure the documentation explicitly links the arthropathy to a prior rheumatic fever episode.
• Verify the laterality is specified as "right hand"; otherwise, an unspecified laterality code may be more appropriate.
• Differentiate from other forms of inflammatory or degenerative arthritis affecting the hand, as Jaccoud's arthropathy has a distinct etiology and presentation.
