CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

I08 is a non-billable ICD-10-CM category code for multiple valve diseases, so it cannot be submitted on claims. Use a more specific code from this category instead, such as I08.0, I08.1, I08.2, and I08.3.

Specific Coding for Multiple valve diseasesOverview

Non-specific codes like I08 require more characters. Use one of these billable codes instead:

  • Use I08.0 for Rheumatic disorders of both mitral and aortic valves

  • Use I08.1 for Rheumatic disorders of both mitral and tricuspid valves

  • Use I08.2 for Rheumatic disorders of both aortic and tricuspid valves

  • Use I08.3 for Combined rheumatic disorders of mitral, aortic and tricuspid valves

  • Use I08.8 for Other rheumatic multiple valve diseases

  • Use I08.9 for Rheumatic multiple valve disease, unspecified

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to I08: its own notes plus those printed at Chapter 9. A note printed at a category, block or chapter applies to every code under it.

Includes

Further defines, or gives examples of, the content of the category.

  • multiple valve diseases specified as rheumatic or unspecified

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

  • endocarditis, valve unspecified (I38)
  • rheumatic valve disease NOS (I09.1)

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

On I08 itself
From Chapter 9 (I00-I99) Diseases of the circulatory system applies to 1,433 codes
  • certain conditions originating in the perinatal period (P04-P96)
  • certain infectious and parasitic diseases (A00-B99)
  • complications of pregnancy, childbirth and the puerperium (O00-O9A)

Excludes2 3

These codes carry an Excludes2 note naming I08: its condition is not part of those codes, and both may be reported when the patient has both.

Questions About I08Overview

What is the ICD-10 code for multiple valve diseases?

I08 is the ICD-10-CM category for multiple valve diseases, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is I08 (Multiple valve diseases) a billable code?

No. This is a category header that groups the codes for multiple valve diseases, and headers cannot be submitted on claims. Claims for multiple valve diseases need a more specific code from this category, such as I08.0, I08.1, and I08.2.

Can I08 be reported with I38?

Not as a rule. The Excludes1 note on I08 lists "endocarditis, valve unspecified (I38)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
