Rheumatic aortic valve diseases (I06) ICD-10-CM
The I06 code range covers rheumatic aortic valve diseases with 6 ICD-10-CM diagnosis codes. 5 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

About the I06 Code Range
Rheumatic disease can affect the heart’s aortic valve. This category sits within chronic rheumatic heart diseases and separates valve narrowing, called stenosis, from insufficiency, or leakage.
I06.0 describes stenosis, while I06.1 describes insufficiency. I06.2 describes both together. I06.8 covers other rheumatic aortic valve diseases, and I06.9 does not specify the valve disease.
