Code Description

ICD-10 O23.512 is a billable code used to indicate a diagnosis of infections of cervix in pregnancy, second trimester.

Key Diagnostic Point:

Infections of the cervix during pregnancy can pose significant risks to both the mother and the fetus. In the second trimester, these infections may be caused by various pathogens, including sexually transmitted infections (STIs) such as Chlamydia trachomatis and Neisseria gonorrhoeae, as well as bacterial vaginosis and other bacterial infections. Symptoms may include abnormal vaginal discharge, pelvic pain, and bleeding. If left untreated, cervical infections can lead to complications such as preterm labor, chorioamnionitis, and increased risk of cesarean delivery. Diagnosis typically involves a thorough clinical evaluation, including pelvic examination and laboratory testing. Treatment often includes the use of antibiotics that are safe for use during pregnancy, such as azithromycin or amoxicillin, depending on the specific pathogen identified. Close monitoring and follow-up care are essential to ensure maternal and fetal well-being.

Complexity Factors

  • Differentiating between types of cervical infections
  • Understanding antibiotic safety profiles in pregnancy
  • Documenting symptoms and clinical findings accurately
  • Navigating potential complications and their coding

Audit Risk Factors

  • Inadequate documentation of infection type
  • Failure to document antibiotic treatment and response
  • Misclassification of infection severity
  • Lack of follow-up notes on maternal and fetal outcomes

Specialty Focus

Medical Specialties

Obstetrics and Gynecology

Documentation Requirements

Detailed documentation of symptoms, diagnostic tests, and treatment plans is essential. Include any relevant history of STIs or previous cervical issues.

Common Clinical Scenarios

A pregnant patient presents with abnormal discharge and pelvic pain; a cervical culture is performed to identify the causative organism.

Billing Considerations

Consider the implications of untreated infections on pregnancy outcomes and ensure that all relevant clinical findings are documented.

Maternal-Fetal Medicine

Documentation Requirements

Comprehensive documentation of maternal-fetal assessments, including ultrasound findings and any interventions performed.

Common Clinical Scenarios

A high-risk pregnancy patient with a history of cervical incompetence presents with signs of infection; close monitoring and potential intervention are required.

Billing Considerations

High-risk patients may require additional testing and follow-up, which should be clearly documented to support coding.

Coding Guidelines
