Questions About I74Overview

What is the ICD-10 code for arterial embolism and thrombosis?

I74 is the ICD-10-CM category for arterial embolism and thrombosis, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is I74 (Arterial embolism and thrombosis) a billable code?

No. This is a category header that groups the codes for arterial embolism and thrombosis, and headers cannot be submitted on claims. Claims for arterial embolism and thrombosis need a more specific code from this category, such as I74.01, I74.09, and I74.10.

What is coded first with I74?

The Code First note reads: embolism and thrombosis complicating abortion or ectopic or molar pregnancy (O00-O07, O08.2); embolism and thrombosis complicating pregnancy, childbirth and the puerperium (O88.-). When one of these applies, it is sequenced before I74.
