Rheumatic tricuspid stenosis

This code signifies a narrowing of the tricuspid valve opening due to rheumatic fever. This narrowing impedes blood flow from the right atrium to the right ventricle, leading to increased pressure in the right atrium and systemic venous congestion. It is a chronic sequela of rheumatic heart disease.

Use this code when documentation explicitly states tricuspid stenosis and attributes its etiology to rheumatic fever. This diagnosis is typically supported by echocardiogram findings demonstrating valve thickening and restricted leaflet motion, along with a history of rheumatic fever.

• Ensure documentation clearly links the tricuspid stenosis to a rheumatic origin; otherwise, a non-rheumatic tricuspid stenosis code may be more appropriate.
• Always sequence this code after any active rheumatic fever codes (e.g., I00-I02) if the rheumatic process is still active.
• Look for associated conditions like rheumatic mitral or aortic valve disease, which often coexist and should be coded separately.
