Code Description

ICD-10 O25 is a billable code used to indicate a diagnosis of malnutrition in pregnancy, childbirth and the puerperium.

Key Diagnostic Point:

Malnutrition during pregnancy, childbirth, and the puerperium can significantly impact maternal and fetal health. It encompasses a range of nutritional deficiencies, including undernutrition and overnutrition, which can lead to adverse outcomes such as low birth weight, preterm birth, and developmental issues in the infant. Malnutrition may arise from various factors, including socioeconomic status, eating disorders (such as anorexia nervosa or bulimia), and inadequate access to nutritious food. Pregnant women with eating disorders may experience severe malnutrition, which can complicate their pregnancy and increase the risk of complications during childbirth. Nutritional counseling is essential for these patients to ensure they receive adequate nutrients to support both their health and the health of their developing fetus. Healthcare providers must assess dietary intake, provide education on healthy eating habits, and monitor weight gain throughout pregnancy to mitigate risks associated with malnutrition.
