Rheumatoid heart disease w rheumatoid arthritis of left hand

This code signifies a systemic autoimmune disorder characterized by chronic inflammatory arthritis affecting the left hand, specifically complicated by cardiac involvement. The heart disease is a direct manifestation of the rheumatoid arthritis, indicating a more severe and widespread disease process.

Apply this code when documentation explicitly states rheumatoid arthritis affecting the left hand, along with a diagnosis of rheumatoid heart disease. This typically occurs in patients with long-standing or aggressive rheumatoid arthritis where cardiac complications such as pericarditis, myocarditis, or valvular disease have developed.

• Ensure documentation clearly links the heart disease to the rheumatoid arthritis, rather than other cardiac etiologies.
• Always code the specific type of rheumatoid heart disease (e.g., pericarditis, myocarditis) as a secondary diagnosis if documented.
• Verify laterality for the affected hand; this code is specific to the left hand.
