O23.522 Salpingo-oophoritis in pregnancy, second trimester

Name of the Condition

• Salpingo-oophoritis in pregnancy, second trimester
• ICD-10 Code: O23.522

Summary

Salpingo-oophoritis in pregnancy, second trimester, refers to inflammation of the fallopian tubes and ovaries during the second trimester of pregnancy. This condition may result from ascending infections or hematogenous spread and requires prompt evaluation to prevent complications for both the mother and fetus. Management focuses on identifying the underlying cause and initiating appropriate treatment to reduce risks of adverse outcomes.

Causes

Salpingo-oophoritis in pregnancy, second trimester, is often caused by bacterial pathogens, such as Chlamydia trachomatis, Neisseria gonorrhoeae, or other ascending infections from the lower genital tract. Hormonal changes and altered immune responses during pregnancy can increase susceptibility to infection. Pelvic inflammatory disease (PID) or untreated genital tract infections may also contribute to the development of this condition.

Risk Factors

• Previous history of pelvic inflammatory disease or salpingo-oophoritis.
• Untreated or recurrent genital tract infections.
• Multiple sexual partners or unprotected intercourse.
• Invasive procedures during pregnancy (e.g., cervical dilation).
• Underlying immunosuppression or diabetes.
• Prolonged rupture of membranes.

Symptoms

• Pelvic or lower abdominal pain (often unilateral).
• Abnormal vaginal discharge (color, odor, or consistency changes).
• Fever or chills.
• Nausea or vomiting.
• Dyspareunia (pain during intercourse).
• Urinary symptoms (e.g., frequency, urgency).

Diagnosis

Diagnosis involves a combination of clinical evaluation, pelvic examination, and laboratory testing. Cultures or nucleic acid amplification tests (NAATs) of vaginal or cervical specimens may identify causative pathogens. Imaging, such as ultrasound, can assess for tubal or ovarian involvement. Blood tests, including complete blood count (CBC) and inflammatory markers (e.g., C-reactive protein), may support the diagnosis. Clinical judgment is essential to differentiate from other causes of abdominal pain in pregnancy.

Treatment Options

Treatment typically includes antibiotics targeted at common pathogens, such as Chlamydia trachomatis or Neisseria gonorrhoeae. Hospitalization may be necessary for severe cases or if the mother or fetus is unstable. Supportive care, including hydration and pain management, is often provided. Close monitoring of maternal and fetal status is critical throughout treatment.

Prognosis and Follow-Up

With prompt and appropriate treatment, outcomes are generally favorable, but complications can occur. Follow-up includes monitoring for resolution of symptoms and repeat testing if needed. Regular prenatal care is essential to assess fetal well-being and maternal recovery. Long-term follow-up may be required for recurrent infections or fertility concerns.

Complications

• Preterm labor or delivery.
• Pelvic abscess formation.
• Sepsis or maternal septic shock.
• Fetal growth restriction.
• Increased risk of ectopic pregnancy in future pregnancies.
• Chronic pelvic pain.

Lifestyle & Prevention

• Practice safe sex to reduce sexually transmitted infection risk.
• Maintain good genital hygiene.
• Attend regular prenatal visits for early detection and treatment of infections.
• Avoid douching or irritants that may disrupt vaginal flora.
• Promptly treat any genital tract infections during pregnancy.

When to Seek Professional Help

Seek immediate medical attention if experiencing severe abdominal pain, fever, vaginal bleeding, or signs of infection (e.g., chills, nausea). Contact a healthcare provider for persistent pelvic pain, abnormal discharge, or concerns about fetal movement. Early evaluation is crucial to prevent complications.

Tips for Medical Coders

When coding O23.522, ensure documentation specifies the second trimester and confirms salpingo-oophoritis. Verify that the condition is linked to pregnancy and not a pre-existing or postpartum issue. Include details on causative organisms or treatment if available, as these may support code specificity. Follow guidelines for trimester assignment and exclude codes for unrelated infections.
