ICD-10 Code I06.1 – Rheumatic aortic insufficiency (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I06.1 – Rheumatic aortic insufficiency
What it is
I06.1 identifies rheumatic damage to the aortic valve that causes leakage, also called aortic regurgitation or insufficiency. Use it when the record links the valve problem to rheumatic heart disease.
Clinical signs
Common findings include a diastolic murmur and evidence of aortic valve regurgitation on examination or imaging. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents rheumatic aortic insufficiency, rheumatic aortic regurgitation, or rheumatic involvement of the aortic valve with leakage. It is appropriate when the condition is clearly attributed to rheumatic heart disease. If the chart only says aortic insufficiency without a rheumatic cause, check documentation.
Do not use for
Do not use I06.1 for nonrheumatic aortic valve insufficiency or for isolated aortic stenosis. If the etiology is unclear, check documentation before assigning the code.
Coding tip
Code the rheumatic cause only when the provider documents that link explicitly.
