Chronic postrheumatic arthropathy [Jaccoud], left shoulder

This diagnosis code signifies a chronic joint disorder affecting the left shoulder, specifically one that develops as a sequela of rheumatic fever, often characterized by non-erosive, deforming arthropathy. It represents the long-term joint damage and functional impairment resulting from a previous rheumatic fever episode, distinct from acute rheumatic arthritis.

Assign this code when documentation clearly indicates chronic arthropathy of the left shoulder attributed to a history of rheumatic fever, often referred to as Jaccoud's arthropathy. This code is appropriate for patients presenting with persistent joint deformity, pain, or limited range of motion in the left shoulder, where a causal link to prior rheumatic fever has been established.

• Ensure documentation specifies "chronic" and explicitly links the arthropathy to a history of rheumatic fever.
• Laterality is crucial; verify the affected side is the left shoulder.
• Do not confuse with acute rheumatic arthritis (M06.0-M06.9) or other forms of chronic arthropathy not related to rheumatic fever.
