2026 ICD-10-CM Diagnosis Code I74Arterial embolism and thrombosis
I74 is a non-billable ICD-10-CM category code for arterial embolism and thrombosis, so it cannot be submitted on claims. Use a more specific code from this category instead, such as I74.01, I74.09, I74.10, and I74.11.

This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
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.
