ICD-10 Code I07.0 – Rheumatic tricuspid stenosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I07.0 – Rheumatic tricuspid stenosis
What it is
This code identifies narrowing of the tricuspid valve caused by rheumatic heart disease. It means blood flow from the right atrium to the right ventricle is obstructed because of prior rheumatic damage.
Clinical signs
Findings may include signs of right-sided heart strain, such as fatigue, edema, or jugular venous distention. Clinical features vary; refer to documentation, and confirm the rheumatic origin when recorded.
When to use this code
Use I07.0 when the provider documents rheumatic tricuspid stenosis as the diagnosis. It also fits encounter records that clearly describe tricuspid stenosis due to rheumatic disease, even if the note uses equivalent wording.
Do not use for
Do not use this code for nonrheumatic tricuspid stenosis or for tricuspid regurgitation alone. If the record does not specify rheumatic cause, check documentation.
Coding tip
Code the rheumatic etiology only when the provider states it explicitly or links the valve lesion to rheumatic heart disease.
