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 2026, and the category headers group them but cannot themselves be billed.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

About the I06 Code Range
The ICD-10 code I06 series covers rheumatic aortic valve diseases, which are heart valve conditions caused by rheumatic fever affecting the aortic valve. These codes are used to classify specific problems like narrowing or leaking of the aortic valve due to rheumatic heart disease.
The ICD-10 code for rheumatic aortic stenosis (I06.0) describes narrowing of the aortic valve, also known as rheumatic aortic valve obstruction. Rheumatic aortic insufficiency (I06.1) represents leaking of the valve, sometimes called rheumatic aortic regurgitation. When both narrowing and leaking occur together, I06.2 applies, capturing combined rheumatic aortic stenosis with insufficiency. Other less common or unspecified rheumatic aortic valve problems are coded as I06.8 and I06.9, respectively. The synonyms such as “rheumatic aortic valve sclerosis” or “valvular sclerosis” help medical coders link various descriptions of these rheumatic valve conditions to the correct ICD-10 code. These codes specifically identify chronic rheumatic heart disease affecting the aortic valve and guide accurate clinical diagnosis and billing for this group of valve disorders.
