O34.0Maternal care for congenital malformation of uterus

O34.0 is the ICD-10-CM diagnosis code for maternal care for congenital malformation of uterus. It belongs to category O34 (maternal care for abnormality of pelvic organs), block O30-O48 (maternal care related to the fetus and amniotic cavity and possible delivery problems) and chapter 15 (pregnancy, childbirth and the puerperium).

Related codes cover for benign tumor of corpus uteri (O34.1), due to uterine scar from previous surgery (O34.2), for cervical incompetence (O34.3), for other abnormalities of cervix (O34.4), for other abnormalities of gravid uterus (O34.5), for abnormality of vagina (O34.6), for abnormality of vulva and perineum (O34.7), for other abnormalities of pelvic organs (O34.8) and 1 more.
