Questions About O88Overview

What is the ICD-10 code for obstetric embolism?

O88 is the ICD-10-CM category for obstetric embolism, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is O88 (Obstetric embolism) a billable code?

No. This is a category header that groups the codes for obstetric embolism, and headers cannot be submitted on claims. Claims for obstetric embolism need a more specific code from this category, such as O88.011, O88.012, and O88.013.

Can O88 be reported with O03.2?

Not as a rule. The Excludes1 note on O88 lists "embolism complicating abortion NOS (O03.2)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
