Other maternal disorders predominantly related to pregnancy (O20-O29)

ICD-10 codes O20-O29 cover a variety of maternal disorders primarily related to pregnancy, including bleeding complications, excessive vomiting, venous issues, infections, diabetes, malnutrition, and anesthesia-related complications during pregnancy, childbirth, and the postpartum period.

This range includes codes like O20 for early pregnancy hemorrhage and O21 for excessive vomiting, also known as hyperemesis gravidarum. Venous complications and hemorrhoids during pregnancy are classified under O22, with detailed codes for varicose veins, thrombophlebitis, and cerebral venous thrombosis. Infections of the genitourinary tract in pregnancy, including kidney, bladder, and genital tract infections, fall under O23. Diabetes mellitus in pregnancy, with distinctions for type 1, type 2, gestational, and other forms, is captured by codes in O24. Malnutrition related to pregnancy is found under O25. The O26 codes address maternal care issues such as excessive or low weight gain, fatigue, renal disease, and other pregnancy-related complications like cervical shortening and pruritic urticarial papules (PUPPP). Abnormal antenatal screening results are coded in O28. Finally, anesthesia complications during pregnancy, including pulmonary, cardiac, CNS issues, and reactions to local anesthesia, are detailed in the O29 series. These codes help capture specific maternal conditions that can impact pregnancy management and outcomes.
