Rheumatoid heart disease w rheumatoid arthritis of left hip

This code signifies a systemic autoimmune disorder characterized by chronic inflammation affecting the left hip joint, specifically due to rheumatoid arthritis, and concurrently involving the heart. The heart involvement is a direct manifestation of the rheumatoid disease process, rather than a separate cardiac condition.

Apply this code when documentation explicitly states rheumatoid arthritis affecting the left hip, along with a diagnosis of rheumatoid heart disease. This typically occurs in patients with long-standing or severe rheumatoid arthritis where cardiac complications, such as pericarditis, myocarditis, or valvular disease, are attributed to the underlying autoimmune condition.

• Ensure documentation clearly links the heart disease to the rheumatoid arthritis.
• Do not use this code for non-rheumatoid cardiac conditions occurring in a patient with rheumatoid arthritis.
• Always sequence this code before any specific cardiac manifestations (e.g., I09.0 for rheumatoid pericarditis) to indicate the underlying etiology.
