O00-O08: Pregnancy with abortive outcome

O06: Unspecified abortion

Unspecified abortion, a group of conditions related to pregnancy loss, includes instances where a woman's pregnancy ends unexpectedly before the 20th week without a solidly determined cause. Conditions under this category often come with similar symptoms including vaginal bleeding, abdominal cramping, and a halt in pregnancy symptoms. These conditions can be spontaneous but are sometimes caused due to complications such as chromosomal abnormalities in the fetus, maternal diseases, advanced maternal age, or lifestyle factors such as smoking and substance abuse. Progression of these conditions varies, as some may resolve naturally while others may lead to further complications. Irrespective of the cause, these conditions tend to affect the reproductive system, causing significant physiological changes. They can also have profound emotional impacts, contributing to psychological distress.
