I74Arterial embolism and thrombosis

Non-billable headerICD-10-CM

I74 is a non-billable header ICD-10-CM code for arterial embolism and thrombosis. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

  • atheroembolism (I75.-)
  • basilar embolism and thrombosis (I63.0-I63.2, I65.1)
  • carotid embolism and thrombosis (I63.0-I63.2, I65.2)
  • cerebral embolism and thrombosis (I63.3-I63.5, I66.-)
  • coronary embolism and thrombosis (I21-I25)

The underlying condition must be sequenced before this code.

  • embolism and thrombosis complicating abortion or ectopic or molar pregnancy (O00-O07, O08.2)
  • embolism and thrombosis complicating pregnancy, childbirth and the puerperium (O88.-)

Conditions this code covers.

  • embolic infarction
  • embolic occlusion
  • thrombotic infarction
  • thrombotic occlusion

Risk adjustment

I74 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.

Code to one of these instead I74

8 child codes. Green means billable.
