Chronic postrheumatic arthropathy, right ankle and foot

This code describes a chronic, non-erosive joint disease affecting the right ankle and foot, characterized by deformities such as ulnar deviation of the fingers and subluxation, typically following an episode of rheumatic fever. It represents a long-term sequela of rheumatic fever, distinct from acute inflammatory processes.

Use this code for patients presenting with chronic, non-inflammatory joint deformities of the right ankle and foot, specifically documented as Jaccoud's arthropathy or chronic postrheumatic arthropathy. Documentation should clearly link the arthropathy to a prior history of rheumatic fever and specify the affected laterality.

• Ensure documentation explicitly states "Jaccoud's arthropathy" or "chronic postrheumatic arthropathy" and specifies the right ankle and foot.
• Do not confuse with acute rheumatic fever with cardiac involvement (I00-I02) or other types of inflammatory arthropathies.
• Verify laterality; separate codes exist for the left ankle and foot (M12.072) and bilateral involvement (M12.073).
