Chronic postrheumatic arthropathy, other specified site

This code describes a chronic joint disorder characterized by deformities, particularly of the hands and feet, that develop after an episode of acute rheumatic fever. It is a non-erosive arthropathy, meaning it does not cause destruction of the joint cartilage or bone, but rather ligamentous laxity leading to characteristic deformities.

Assign this code when documentation clearly indicates a diagnosis of Jaccoud's arthropathy affecting a site other than those specifically classified (e.g., shoulder, hip, knee). The patient's history must include a prior diagnosis of acute rheumatic fever. Documentation should specify the affected joint(s) if not otherwise classified.

• Ensure documentation explicitly links the arthropathy to a history of rheumatic fever.
• Do not confuse Jaccoud's arthropathy with rheumatoid arthritis; it is a distinct post-rheumatic condition.
• Code the specific affected joint(s) if a more precise code is available within the M12.0 subcategory. This code is for "other specified site."
