About O34.7
O34.7 is the ICD-10-CM diagnosis code for maternal care for abnormality of vulva and perineum. 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). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.
Within O34 (maternal care for abnormality of pelvic organs), O34.7 is specifically for maternal care for abnormality of vulva and perineum. Related codes cover for congenital malformation of uterus (O34.0), 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 other abnormalities of pelvic organs (O34.8) and 1 more.
To report this condition, pick the subcode that matches the documentation: O34.70 (unspecified trimester), O34.71 (first trimester), O34.72 (second trimester) and O34.73 (third trimester).
The conditions in its Excludes2 note aren't part of O34.7, but may be coded alongside it if the patient has both: maternal care for perineal and vulval varices in pregnancy (O22.1-).
Code first: any associated obstructed labor (O65.5).
Use an additional code for specific condition.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
