Code Description

ICD-10 O23.511 is a billable code used to indicate a diagnosis of infections of cervix in pregnancy, first trimester.

Key Diagnostic Point:

Infections of the cervix during the first trimester of pregnancy can pose significant risks to both maternal and fetal health. These infections may include cervicitis caused by sexually transmitted infections (STIs) such as Chlamydia trachomatis and Neisseria gonorrhoeae, as well as other bacterial infections. The presence of cervical infections can lead to complications such as preterm labor, premature rupture of membranes, and increased risk of vertical transmission of pathogens to the fetus. Early diagnosis and appropriate management are crucial to mitigate these risks. Treatment typically involves the use of antibiotics that are safe for use during pregnancy, as certain medications can adversely affect fetal development. Regular prenatal care and screening for STIs are essential components of obstetric care to ensure the health of both the mother and the developing fetus.
