O00.21 Ovarian pregnancy with intrauterine pregnancy

Name of the Condition

• Ovarian pregnancy with intrauterine pregnancy

Summary

This condition involves the simultaneous occurrence of a pregnancy located in the ovaries and a regular intrauterine pregnancy. It is a rare form of heterotopic pregnancy, where two gestational sacs are present, one in the uterus and the other ectopically outside the uterine cavity.

Causes

Heterotopic pregnancies such as this may occur in natural conception or are more frequently associated with assisted reproductive technologies like in vitro fertilization.

Risk Factors

• Use of fertility treatments, particularly those involving ovulation induction.
• Previous history of ectopic pregnancies.
• Pelvic inflammatory disease.
• Previous pelvic surgery.

Symptoms

• Symptoms can be similar to those of an ectopic pregnancy, including pelvic pain, spotting, or bleeding.
• Abdominal pain or discomfort might also be experienced.

Diagnosis

Ultrasound imaging is essential for identifying the locations of both gestational sacs. Blood tests, particularly checking human chorionic gonadotropin (hCG) levels, may provide additional insight.

Treatment Options

• Treatment typically involves surgical intervention to remove the ectopic ovarian pregnancy, often through laparoscopy, while carefully preserving the intrauterine pregnancy.
• In certain cases, medication may be considered, though this is less common due to the need to protect the intrauterine pregnancy.

Prognosis and Follow-Up

The prognosis depends on early diagnosis and appropriate management. Close monitoring of the intrauterine pregnancy is necessary, and follow-up care should include regular ultrasounds and hCG level checks to ensure both pregnancies progress safely.

Complications

• Rupture of the ovarian pregnancy, leading to internal bleeding.
• Loss of the intrauterine pregnancy due to the ectopic condition.
• Pelvic infection or scarring.

Lifestyle & Prevention

• Avoiding unnecessary pelvic surgery when possible.
• Prompt treatment of pelvic inflammatory disease to reduce tubal damage.
• Discussing risks with a healthcare provider before starting fertility treatments.

When to Seek Professional Help

Seek immediate medical attention if experiencing severe pelvic pain, heavy vaginal bleeding, dizziness, or fainting, as these may indicate a ruptured ectopic pregnancy.

Tips for Medical Coders

Document the presence of both ovarian and intrauterine pregnancies clearly in the medical record. Ensure the code O00.21 is used only when both locations are confirmed, and specify any surgical or medical interventions performed.
