    ICD-10-CM Code For Malnutrition In Pregnancy Childbirth And The Puerperium: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group O25 includes maternal malnutrition diagnoses occurring during pregnancy, labor and delivery, or the puerperium, covering protein-energy malnutrition and other nutritional deficiencies that complicate pregnancy. These ICD-10-CM diagnosis codes are used to document maternal nutritional status and related complications, capturing severity, timing in the peripartum period, and clinical complexity relevant to prenatal and postpartum care. Accurate coding within the ICD-10-CM O25 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM O25: Malnutrition In Pregnancy, Childbirth And The Puerperium Overview

    This group includes diagnoses for malnutrition occurring in pregnancy, during childbirth, and the puerperium, affecting maternal nutritional status and fetal development. These conditions involve maternal metabolic and nutritional systems and can impact pregnancy outcomes and postpartum recovery. Accurate coding matters for clinical records and reimbursement because it documents severity and guides appropriate resource allocation.

    When to Use

    Use a code from this group when a pregnant or postpartum patient has documented malnutrition or a specific nutritional deficiency that complicates pregnancy, labor, delivery, or the puerperium. Select the code that reflects the documented type and severity of malnutrition and the timing in relation to pregnancy or the postpartum period.

    Typical Clinical Scenarios

    • A first-trimester woman with severe nausea and vomiting (hyperemesis gravidarum) presents to the obstetric clinic with persistent inability to tolerate oral intake for several days, rapid weight loss, and signs of dehydration and electrolyte disturbance. Nutritional assessment reveals significant caloric and protein deficiency related to pregnancy, and a nutrition-focused diagnosis from this group is assigned to document pregnancy-associated malnutrition requiring monitoring and possible intervention. Typical codes: O25.10, O25.11
    • A pregnant patient in the second trimester with chronic inadequate dietary intake and progressive maternal weight loss is followed in a high-risk prenatal clinic for poor fetal growth and maternal nutrient deficiency. Because the malnutrition is ongoing and affects pregnancy management, a pregnancy-related malnutrition diagnosis is used to capture the underlying maternal nutritional disorder contributing to fetal growth concerns and the need for nutritional support. Typical codes: O25.12, O25.13
    • A postpartum patient admitted for wound healing complications after cesarean delivery is found to have protein-energy malnutrition impairing recovery; documentation links the malnutrition to pregnancy and the puerperium period. The care team assigns a code from this group to reflect malnutrition as a comorbidity complicating the postpartum course and affecting management of the surgical site infection and recovery. Typical codes: O25.2, O25.3
