O88Obstetric embolism

Non-billable headerICD-10-CM

O88 is a non-billable header ICD-10-CM code for obstetric embolism. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • embolism complicating abortion NOS (O03.2)
  • embolism complicating ectopic or molar pregnancy (O08.2)
  • embolism complicating failed attempted abortion (O07.2)
  • embolism complicating induced abortion (O04.7)
  • embolism complicating spontaneous abortion (O03.2, O03.7)

Other codes that can never be billed with O88

These codes carry an Excludes1 note pointing at O88. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading O88 alone.

  • O85Puerperal sepsis
  • T79.1XXSFat embolism (traumatic), sequela
  • T79.0Air embolism (traumatic)
  • T79.0XXAAir embolism (traumatic), initial encounter
  • T79.0XXDAir embolism (traumatic), subsequent encounter
  • T79.0XXSAir embolism (traumatic), sequela
  • T79.1Fat embolism (traumatic)
  • T79.1XXAFat embolism (traumatic), initial encounter

Risk adjustment

O88 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 O88

5 child codes. Green means billable.
