O31.02 Papyraceous fetus, second trimester

Name of the Condition

• Papyraceous fetus, second trimester (ICD Code: O31.02)

Summary

Papyraceous fetus, second trimester, refers to a non-viable fetus that dies during the second trimester of pregnancy and undergoes mummification, resulting in a flattened, parchment-like appearance. This occurs when the fetal tissue dehydrates and compresses after death, often in the context of multiple gestation or other intrauterine factors.

Causes

The condition arises from fetal death in the second trimester, typically due to placental insufficiency, chromosomal abnormalities, or other mid-pregnancy complications. The fetal remains then undergo dehydration and compression, leading to the characteristic papyraceous appearance.

Risk Factors

• Multiple gestation (e.g., twins or higher-order pregnancies)
• Placental abnormalities affecting mid-pregnancy viability
• Maternal health conditions impacting second-trimester pregnancy
• Prior mid-pregnancy loss

Symptoms

• Often asymptomatic; detected incidentally during second-trimester imaging
• Possible vaginal spotting or mild cramping if associated with pregnancy loss
• Absence of fetal cardiac activity on ultrasound

Diagnosis

Prenatal ultrasound is the primary diagnostic tool, showing a flattened, calcified fetal remnant consistent with papyraceous change. Maternal serum hCG levels may be monitored to assess pregnancy viability. Clinical evaluation to rule out other complications or infections.

Treatment Options

• Expectant Management: Monitoring for spontaneous expulsion of fetal tissue.
• Medication: Misoprostol to induce uterine contractions if needed.
• Dilation and Curettage (D&C): Surgical removal of fetal tissue in some cases.

Prognosis and Follow-Up

Prognosis depends on underlying causes and maternal health. Most cases resolve without long-term maternal complications. Follow-up includes monitoring for infection, bleeding, or retained tissue. Future pregnancy planning may involve genetic counseling if chromosomal abnormalities are suspected.

Complications

• Infection (e.g., endometritis)
• Retained fetal tissue
• Emotional distress related to pregnancy loss
• Potential impact on future fertility (rare)

Lifestyle & Prevention

• Prenatal care to monitor fetal health and address risk factors.
• Avoidance of teratogens (e.g., alcohol, certain medications).
• Management of chronic conditions (e.g., hypertension, diabetes) before and during pregnancy.

When to Seek Professional Help

Seek care if experiencing vaginal bleeding, severe cramping, fever, or signs of infection after diagnosis. Prompt evaluation is important to address complications and emotional support.

Tips for Medical Coders

Document the trimester (second trimester) and confirm the papyraceous change via imaging or clinical findings. Ensure the code aligns with the timing of fetal demise and associated clinical details.
