ICD-10 Code I07.8 – Other rheumatic tricuspid valve diseases (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I07.8 – Other rheumatic tricuspid valve diseases
What it is
This code identifies rheumatic disease affecting the tricuspid valve that does not fit a more specific rheumatic tricuspid diagnosis. Use it when documentation clearly links the valve disorder to rheumatic heart disease.
Clinical signs
Findings may include tricuspid valve dysfunction, such as regurgitation or stenosis, with evidence of rheumatic origin. Clinical features vary; refer to documentation.
When to use this code
Use I07.8 when the provider documents rheumatic tricuspid valve disease and does not specify another exact rheumatic tricuspid code. It may appear in cardiology notes, echocardiogram interpretations, or discharge summaries. Make sure the record supports a rheumatic etiology.
Do not use for
Do not use this code for nonrheumatic tricuspid valve disease or for unspecified valvular findings without rheumatic linkage. Check documentation if the cause or valve type is unclear.
Coding tip
Confirm both the tricuspid valve involvement and the rheumatic cause before assigning I07.8.
