Miscarriage ICD-10-CM Codes | 2025

A miscarriage, also called a spontaneous abortion, is the loss of a pregnancy before 20 weeks of gestation. Pregnancy losses after the 20th week are called stillbirths.

Common risk factors include advanced maternal age, previous miscarriages, certain chronic conditions (like diabetes or thyroid disease), infections, uterine abnormalities, smoking, alcohol use, and high stress levels.

After a miscarriage, the body typically experiences cramping and vaginal bleeding as it expels pregnancy tissue and begins to recover. Hormone levels gradually decrease, and physical symptoms such as breast tenderness and fatigue may occur, along with emotional responses that vary from person to person.
