Missed abortion

This code signifies a fetal death that has occurred in utero, but the products of conception have not yet been expelled from the uterus. The patient may or may not experience symptoms such as vaginal bleeding or cramping, and the diagnosis is typically confirmed by ultrasound showing absence of fetal cardiac activity.

Use this code when documentation clearly indicates a confirmed intrauterine fetal demise where the uterus still contains the non-viable pregnancy. This often occurs after an initial ultrasound shows a gestational sac or embryo, but subsequent imaging reveals no fetal heart activity or growth arrest.

• Ensure documentation specifies "missed abortion" or "retained products of conception after fetal demise" to differentiate from other types of abortions.
• Do not use this code if the products of conception have been completely expelled; consider codes for spontaneous abortion.
• Always review the patient's medical record for the gestational age at the time of diagnosis and any associated complications.
