Threatened abortion

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

Vaginal bleeding or spotting in the first 20 weeks of pregnancy with a risk that the pregnancy may be lost, but the pregnancy continues.

Coding Tips

  • Threatened abortion indicates the pregnancy is still viable; if the pregnancy is lost, use codes for spontaneous abortion instead
  • This code applies only to pregnancies before 20 weeks gestation
