About the O25 Code Range
Malnutrition can occur during pregnancy, childbirth, or the period after childbirth, called the puerperium.
O25 separates these periods. During pregnancy, O25.1 divides into an unspecified trimester (O25.10) and the first (O25.11), second (O25.12), and third (O25.13) trimesters. The other branches identify malnutrition in childbirth (O25.2) or the puerperium (O25.3).
