ICD-10 Code I06.8 – Other rheumatic aortic valve diseases (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I06.8 – Other rheumatic aortic valve diseases
What it is
I06.8 identifies rheumatic disease of the aortic valve that does not fit a more specific rheumatic aortic valve category. Use it when the record clearly links the valve problem to rheumatic heart disease.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include a history of rheumatic fever, aortic valve involvement, and signs of valvular dysfunction on exam or imaging.
When to use this code
Use this code when the provider documents other rheumatic aortic valve disease and no more specific I06 code applies. It is appropriate for rheumatic aortic valve pathology described as residual, unspecified, or otherwise not classifiable under a different rheumatic aortic valve code.
Do not use for
Do not use this code for nonrheumatic aortic valve disorders or for rheumatic mitral valve disease alone. If the documentation names a more specific rheumatic aortic valve condition, code that instead.
Coding tip
Confirm the record explicitly states rheumatic etiology and aortic valve involvement before assigning I06.8.
