- O30-O48 (Maternal care related to the fetus and amniotic cavity and possible delivery problems)
In simple words: This code describes a pregnancy with twins sharing one placenta but having separate sacs around each baby. The pregnancy is between 14 and 28 weeks along.
This code is used to classify a twin pregnancy where the twins share a single placenta (monochorionic) and have separate amniotic sacs (diamniotic).The pregnancy is in the second trimester, defined as gestational weeks 14+0 to 27+6.This code is for maternal records only and should not be used for newborn records.Additional codes may be necessary to capture any associated complications.
Example 1: A 30-year-old woman presents for her routine second-trimester ultrasound. The ultrasound reveals a monochorionic-diamniotic twin pregnancy.The patient is otherwise healthy and has had an uncomplicated pregnancy to date.Code O30.032 is assigned., A 25-year-old woman at 20 weeks gestation with a monochorionic-diamniotic twin pregnancy is experiencing twin-to-twin transfusion syndrome (TTTS).Code O30.032 is used along with codes to specify TTTS and any related complications., A 35-year-old woman at 25 weeks gestation with a monochorionic-diamniotic twin pregnancy presents with preeclampsia. Code O30.032 is used, along with appropriate codes for preeclampsia.
Ultrasound report confirming monochorionic-diamniotic twins, gestational age (in weeks), maternal medical history, any complications, and any other relevant clinical findings.
** This code is solely for maternal records and should not be used to code the newborns.Always confirm the type of twinning (monochorionic/dichorionic) and the number of amniotic sacs (mono/di/polyamniotic) via ultrasound reporting.
