O34.519 Maternal care for incarceration of gravid uterus, unspecified trimester

Name of the Condition

• Maternal care for incarceration of gravid uterus, unspecified trimester

Summary

This condition involves prenatal care for a pregnant woman where the gravid (pregnant) uterus becomes incarcerated, meaning it is trapped in an abnormal position, typically retroverted (tilted backward) and fixed against the sacrum or pelvic sidewall. This can impede normal pregnancy progression and requires specialized monitoring and management. The trimester is not specified in the code.

Causes

The primary cause is the abnormal positioning of the uterus, often due to a retroverted uterus that fails to return to its normal anteverted (forward) position as pregnancy advances. This can be exacerbated by factors like pelvic adhesions, uterine fibroids, or pelvic organ prolapse, which restrict uterine mobility.

Risk Factors

• History of retroverted uterus before pregnancy
• Pelvic adhesions from prior surgery or infection
• Uterine fibroids or other pelvic masses
• Multiparity (having had multiple pregnancies)
• Conditions that reduce pelvic space or mobility

Symptoms

• Abdominal pain or discomfort, often localized to the pelvis
• Difficulty urinating or urinary retention
• Constipation or bowel movement difficulties
• A palpable pelvic mass or fullness
• In severe cases, signs of urinary tract obstruction or bowel obstruction

Diagnosis

Diagnosis is typically made through a combination of physical examination, which may reveal a fixed retroverted uterus, and imaging studies such as ultrasound to confirm the uterine position and assess for complications. Clinical evaluation of symptoms like urinary or bowel obstruction is also key.

Treatment Options

Management focuses on relieving the incarceration, which may include manual repositioning of the uterus, pelvic rest, and monitoring for maternal and fetal well-being. Severe cases may require surgical intervention or close observation to prevent complications.

Prognosis and Follow-Up

With appropriate management, most cases resolve without long-term issues. Follow-up care involves regular monitoring of uterine position, fetal development, and maternal symptoms to ensure the pregnancy progresses normally.

Complications

Potential complications include urinary retention, bowel obstruction, preterm labor, or miscarriage if the incarceration is not addressed promptly. Severe cases may require emergency intervention.

Lifestyle & Prevention

While uterine position is often anatomical, maintaining pelvic health through regular check-ups and addressing pelvic adhesions or masses early may reduce risk. Pelvic exercises or physical therapy are not typically preventive but may aid in mobility if recommended.

When to Seek Professional Help

Seek immediate medical attention if experiencing severe abdominal pain, inability to urinate, or signs of bowel obstruction. Regular prenatal care is essential to monitor for this condition, especially in those with risk factors.

Tips for Medical Coders

Document the trimester if known, as specific trimester codes exist (e.g., first, second, third). For unspecified trimester, use this code. Ensure documentation supports the diagnosis of uterine incarceration and any related management or complications.
