Multiple valve diseases (I08) ICD-10-CM
The I08 code range covers multiple valve diseases with 7 ICD-10-CM diagnosis codes. 6 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- multiple valve diseases specified as rheumatic or unspecified
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.
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 I08 Code Range
Rheumatic multiple valve disease involves more than one heart valve. It falls under chronic rheumatic heart diseases.
The subdivisions identify the valves involved. I08.0 names the mitral and aortic valves; I08.1 names the mitral and tricuspid valves; and I08.2 names the aortic and tricuspid valves. I08.3 names all three. I08.8 describes other rheumatic multiple valve diseases, while I08.9 leaves the multiple valve disease unspecified.
