I74.1 — Embolism and thrombosis of other and unspecified parts of aorta
I74.1 is a non-billable header ICD-10-CM code for embolism and thrombosis of other and unspecified parts of aorta. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes2 inherited from the categories above I74.1
Also inherited, and the opposite of Excludes1: these conditions are not part of I74.1, but a patient can have both, so you may code both.

Risk adjustment
I74.1 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
