About the condition
Plain-language background from MedlinePlus (National Library of Medicine), not coding guidance.
Ectopic Pregnancy
The uterus, or womb, is the place where a fetus grows during pregnancy. In an ectopic pregnancy, the fertilized egg grows in the wrong place outside the uterus. It usually occurs in the fallopian tubes. These tubes carry eggs from the ovaries to the uterus. Sometimes, an ectopic pregnancy can occur in the ovaries, abdominal cavity, or the lower part of the uterus (cervix).
