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 2026, 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
The ICD-10 code for multiple valve diseases (I08) covers various rheumatic disorders affecting more than one heart valve, primarily the mitral, aortic, and tricuspid valves. These codes specify which valves are involved and classify the condition accordingly.
Codes such as I08.0 denote rheumatic disorders of both mitral and aortic valves, also known by terms like Rheumatic mitral valve obstruction or Mitral and aortic stenosis. Similarly, I08.1 and I08.2 correspond to rheumatic involvement of mitral and tricuspid valves or aortic and tricuspid valves, respectively. The code I08.3 describes combined rheumatic diseases affecting mitral, aortic, and tricuspid valves together. For cases that do not fit these specific classifications, I08.8 is used, while I08.9 captures unspecified multiple valve disease, sometimes referred to generally as multiple valve disease. This coding helps healthcare providers document and treat chronic rheumatic heart disease involving multiple heart valves efficiently.
