ICD-10 Code I06.2 – Rheumatic aortic stenosis with insufficiency (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I06.2 – Rheumatic aortic stenosis with insufficiency
What it is
I06.2 identifies rheumatic disease of the aortic valve with both narrowing (stenosis) and leakage (insufficiency). It reflects chronic valvular damage from rheumatic fever, not a congenital or degenerative valve disorder.
Clinical signs
Patients may have a murmur, dyspnea, fatigue, chest discomfort, or signs of heart failure. Clinical features vary; refer to documentation and confirm the rheumatic etiology and combined aortic valve involvement.
When to use this code
Use I06.2 when the record clearly documents rheumatic aortic stenosis with aortic insufficiency, or equivalent wording such as rheumatic aortic valve disease with both stenosis and regurgitation. Apply it when the provider links the valve findings to rheumatic heart disease. If the note only says aortic stenosis or aortic insufficiency without rheumatic cause, check documentation.
Do not use for
Do not use this code for nonrheumatic aortic stenosis, isolated aortic regurgitation, or unspecified valvular disease. Check documentation if the rheumatic origin or combined lesion is not stated.
Coding tip
Verify that both stenosis and insufficiency are documented and that the cause is rheumatic before assigning I06.2.
