O00-O08: Pregnancy with abortive outcome

O05: Other abortion

The group of conditions referred to as "other abortion" generally encompass situations where a pregnancy ends prematurely, but does not fit into typical categories of miscarriage (also called spontaneous abortion) or medical or surgical abortions. These conditions might include what's known as a missed or silent abortion, where the fetus has stopped developing but the body does not expel the pregnancy tissue. Another type is the incomplete abortion, in which only a part of the pregnancy tissue leaves the body. It's difficult to pinpoint a single cause because they can happen due to various reasons such as chromosomal abnormalities, infection, hormonal imbalance, or problems with the body's immune response. Symptoms might include cramping, bleeding, or no symptoms at all, as in the case of missed abortion. These can have an impact on both physical and psychological health, and warrant careful monitoring and management. They do not pass from person to person.
