O46.92 Antepartum hemorrhage, unspecified, second trimester

Name of the Condition

• Antepartum Hemorrhage, Unspecified, Second Trimester

Summary

Antepartum hemorrhage refers to bleeding from the genital tract that occurs during pregnancy after the 20th week of gestation and before childbirth, specifically in the second trimester (13–27 weeks). The term "unspecified" indicates that the exact cause of the bleeding has not been determined.

Causes

The exact cause of antepartum hemorrhage in this category is not specified. It may result from various underlying conditions that are not individually classified, including uterine abnormalities, cervical lesions, or other unidentified sources of bleeding during pregnancy.

Risk Factors

• Previous incidents of antepartum hemorrhage
• History of cesarean delivery
• Multiple pregnancies (twins, triplets)
• Hypertension or preeclampsia
• Smoking
• Maternal age over 35

Symptoms

• Vaginal bleeding
• Uterine contractions or abdominal pain (in some cases)
• Decreased fetal movement (in cases involving placental problems)

Diagnosis

Diagnosis involves a physical examination to assess bleeding and uterine status, ultrasound to evaluate placental position and fetal well-being, and blood tests to check for anemia or coagulation issues. Fetal heart rate monitoring may also be performed.

Treatment Options

• Bed rest and monitoring in mild cases
• Hospitalization in severe cases for intensive monitoring
• Blood transfusions if significant blood loss occurs
• Early delivery, if necessary, depending on gestation and fetal distress

Prognosis and Follow-Up

Prognosis depends on the severity of bleeding, gestational age, and maternal/fetal status. Close follow-up is required to monitor for recurrence or complications. Regular prenatal visits and adherence to medical advice are essential.

Complications

• Maternal anemia or shock from blood loss
• Fetal distress or preterm birth
• Increased risk of placental abnormalities in future pregnancies

Lifestyle & Prevention

• Avoid strenuous activity or heavy lifting
• Attend all prenatal appointments for monitoring
• Report any bleeding or unusual symptoms promptly
• Follow provider recommendations for managing risk factors (e.g., blood pressure control)

When to Seek Professional Help

Seek immediate medical attention for heavy bleeding, severe abdominal pain, dizziness, or reduced fetal movement. Prompt evaluation is critical to assess maternal and fetal well-being.

Tips for Medical Coders

Document the trimester (second) and specify "unspecified" for the cause when no definitive etiology is identified. Ensure clinical documentation supports the diagnosis and aligns with the code’s specificity.
