Code Description

ICD-10 O23.513 is a billable code used to indicate a diagnosis of infections of cervix in pregnancy, third trimester.

Key Diagnostic Point:

Infections of the cervix during the third trimester of pregnancy can pose significant risks to both the mother and the fetus. These infections may include cervicitis, which is often caused by sexually transmitted infections (STIs) such as chlamydia and gonorrhea, as well as bacterial vaginosis and other microbial infections. The presence of cervical infections can lead to complications such as preterm labor, premature rupture of membranes, and increased risk of postpartum infections. It is crucial for healthcare providers to monitor and manage these infections effectively, as they can have lasting effects on maternal and neonatal health. Treatment typically involves the use of antibiotics that are safe for use during pregnancy, ensuring that both the mother and fetus are protected. Regular screening and prompt treatment of cervical infections are essential components of prenatal care, particularly in the third trimester when the risks of complications are heightened.

Complexity Factors

  • Differentiating between types of cervical infections (e.g., bacterial vs. viral)
  • Understanding the implications of STIs on pregnancy outcomes
  • Navigating antibiotic safety and efficacy during pregnancy
  • Documenting the severity and treatment response of infections

Audit Risk Factors

  • Inadequate documentation of infection type and treatment
  • Failure to document patient history related to STIs
  • Lack of follow-up notes on treatment efficacy
  • Misclassification of infection severity

Obstetrics and Gynecology

Documentation Requirements

Detailed documentation of symptoms, diagnostic tests, and treatment plans is essential. Providers should include the patient's obstetric history and any relevant STI screenings.

Common Clinical Scenarios

A patient presents with abnormal vaginal discharge and pelvic pain in the third trimester, requiring evaluation for cervical infection.

Billing Considerations

Coders must ensure that the documentation supports the diagnosis and reflects the urgency of treatment in the third trimester.

Maternal-Fetal Medicine

Documentation Requirements

High-risk pregnancies require comprehensive documentation of maternal and fetal monitoring, including any interventions related to cervical infections.

Common Clinical Scenarios

A high-risk patient with a history of preterm labor presents with signs of cervicitis, necessitating immediate evaluation and treatment.

Billing Considerations

Consideration of the potential impact of infections on fetal health and the need for multidisciplinary care.
