Chronic postrheumatic arthropathy [Jaccoud], unspecified hip

This code describes a chronic, non-inflammatory joint condition affecting an unspecified hip, which develops as a sequela of rheumatic fever. It is characterized by joint deformities, particularly ulnar deviation of the fingers, but in this specific code, it refers to the hip joint. The arthropathy is typically non-erosive and can lead to significant functional impairment.

Use this code when documentation clearly indicates a chronic arthropathy of the hip that is a direct consequence of a previous episode of rheumatic fever, often referred to as Jaccoud's arthropathy. This diagnosis should be supported by a history of rheumatic fever and clinical findings consistent with chronic joint changes in the hip.

• Ensure documentation specifies "chronic" and a clear link to a "postrheumatic" etiology.
• Avoid using this code for acute rheumatic fever with cardiac involvement; instead, use codes from category I00-I02.
• If the specific hip (right or left) is documented, use the more specific codes M12.051 or M12.052.
