ICD-10 Code I08.2 – Rheumatic disorders of both aortic and tricuspid valves (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I08.2 – Rheumatic disorders of both aortic and tricuspid valves
What it is
This code identifies rheumatic heart disease affecting both the aortic and tricuspid valves. Use it when documentation states rheumatic involvement of these two valves together.
Clinical signs
Findings may include murmurs, valve regurgitation or stenosis, and signs of chronic rheumatic valvular disease. Clinical features vary; refer to documentation.
When to use this code
Use I08.2 when the record clearly documents rheumatic disease of both the aortic and tricuspid valves. It may also apply when the clinician specifies combined rheumatic valvular involvement and no more specific code is documented. Check documentation if the valve pathology is not clearly rheumatic.
Do not use for
Do not use this code for nonrheumatic valvular disease or when only one of the two valves is involved. If the chart does not confirm rheumatic etiology, check documentation.
Coding tip
Code the rheumatic valve combination only when both valves are explicitly documented as affected.
