Code Description

ICD-10 O25.12 is a billable code used to indicate a diagnosis of malnutrition in pregnancy, second trimester.

Key Diagnostic Point:

Malnutrition during pregnancy can significantly impact both maternal and fetal health. In the second trimester, the nutritional needs of the mother increase as the fetus undergoes rapid growth and development. Malnutrition may arise from inadequate dietary intake, eating disorders such as anorexia or bulimia, or underlying medical conditions that affect nutrient absorption. This condition can lead to complications such as low birth weight, preterm birth, and developmental delays. Nutritional counseling is essential for pregnant women diagnosed with malnutrition, focusing on balanced diets rich in essential vitamins and minerals. Healthcare providers should assess dietary habits, provide education on healthy eating, and monitor weight gain to ensure both maternal and fetal well-being. Regular follow-ups and interdisciplinary collaboration with dietitians may be necessary to address the complexities of malnutrition in pregnancy.
