Obstetric embolism (O88) ICD-10-CM

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.

Embolism, Amniotic Fluid
Blocking of maternal circulation by AMNIOTIC FLUID that is forced into uterine VEINS by strong UTERINE CONTRACTION near the end of pregnancy. It is characterized by the sudden onset of severe respiratory distress and HYPOTENSION that can lead to maternal DEATH.
About the O88 Code Range
These embolisms occur during pregnancy, childbirth, or the puerperium, the period after childbirth.
The categories distinguish air embolism (O88.0), amniotic fluid embolism (O88.1), thromboembolism (O88.2), pyemic and septic embolism (O88.3), and other embolism (O88.8). Each type splits by whether it occurs during pregnancy, childbirth, or the puerperium. Pregnancy codes split further by trimester, including an unspecified trimester.
