In simple words: This code describes the medical care a mother receives during her third trimester of pregnancy because of a problem with the shape of her uterus that she was born with. This care might include regular checkups, tests, or even a C-section.

This code is used for maternal care related to an unspecified congenital malformation of the uterus that occurs during the third trimester of pregnancy.It encompasses the medical management and care provided to the mother due to this condition, including potential complications and necessary interventions.The code includes care related to hospitalization, obstetric care, and cesarean delivery if applicable.Any associated obstructed labor (O65.5) should be coded first.A further code should be used to specify the exact condition.

Example 1: A 30-year-old woman at 34 weeks gestation presents with severe abdominal pain and is found to have a uterine anomaly causing complications with the pregnancy.The obstetrician manages her condition, ultimately performing a Cesarean section. Code O34.03 is used to capture the maternal care related to the uterine anomaly., A pregnant patient with a known uterine septum presents for routine prenatal care in the third trimester. The care provided includes careful monitoring of fetal well-being and management of potential complications. O34.03 is utilized to bill for this care., A 25-year-old woman at 38 weeks gestation is admitted for preterm labor due to an undiagnosed uterine anomaly. She undergoes emergency C-section. The maternal care necessitated by the anomaly is captured with code O34.03. O65.5 (Obstructed labor) would be coded first.

Detailed documentation of the uterine anomaly, maternal symptoms, clinical findings (ultrasound results, etc.), treatment plan, and the delivery method (vaginal delivery, C-section) is necessary.

** This code is solely for maternal care related to the uterine anomaly.It should not be used on newborn records.Always ensure that the specific uterine malformation is also documented, even if unspecified in the code.Remember to sequence codes correctly if multiple conditions exist.
