Chronic postrheumatic arthropathy, left ankle and foot

This code signifies a chronic joint disease affecting the left ankle and foot, specifically characterized by the deformities and functional limitations associated with Jaccoud's arthropathy, which typically follows an episode of rheumatic fever. It describes a non-erosive, often reversible, but persistent joint involvement.

Use this code when documentation clearly indicates a diagnosis of chronic postrheumatic arthropathy (Jaccoud's) affecting the left ankle and/or foot. This diagnosis is typically made based on a history of rheumatic fever followed by characteristic joint deformities, such as ulnar deviation of the fingers or similar involvement in the foot.

• Ensure documentation specifies "chronic" and links the arthropathy to a prior rheumatic fever episode.
• Verify laterality (left ankle and foot) is clearly stated in the medical record.
• Differentiate from other forms of inflammatory or degenerative arthropathy; Jaccoud's is distinct due to its postrheumatic etiology and non-erosive nature.
