Obstetric embolism (O88) ICD-10-CM
The O88 code range covers obstetric embolism with 41 ICD-10-CM diagnosis codes. 30 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

About the O88 Code Range
The ICD-10 code section O88 covers various types of obstetric embolism, which are serious complications involving emboli such as air, amniotic fluid, thrombi, or infectious material that occur during pregnancy, childbirth, or the postpartum period.
This code group helps healthcare providers precisely classify and document different embolic events specific to obstetrics, including obstetric air embolism (O88.0), amniotic fluid embolism (O88.1), thromboembolism (O88.2), and pyemic and septic embolism (O88.3). Each subtype can be further specified by trimester, childbirth, or puerperium timing. For example, terms like “obstetrical air embolism,” “amniotic fluid pulmonary embolism,” and “pulmonary embolism in childbirth” directly map to these codes. This detailed breakdown guides coders in assigning the proper ICD-10 code for conditions such as arterial air embolus, complications from amniotic fluid entering maternal circulation, blood clots affecting pregnancy stages, and septic emboli linked to infections during pregnancy or postpartum. Using these codes accurately supports clinical clarity and appropriate care management for these rare but critical obstetric emergencies.
