Ectopic Pregnancy ICD-10-CM Codes | 2025

What ICD-10 codes are used for ectopic pregnancy?

Ectopic pregnancy is a potentially life-threatening condition where a fertilized egg implants outside the uterine cavity. Accurate ICD-10 coding is essential for proper diagnosis, treatment, and billing. Below are the ICD-10 codes related to ectopic pregnancy, along with their clinical descriptions:

O00.0: Abdominal pregnancy

A rare form of ectopic pregnancy where the embryo implants within the peritoneal cavity outside the reproductive organs.

Related, more specific codes are the following:

• O00.00: Abdominal pregnancy without intrauterine pregnancy
• O00.01: Abdominal pregnancy with intrauterine pregnancy

O00.1:  Tubal pregnancy

The most common type of ectopic pregnancy, where implantation occurs in the fallopian tubes.

Related, more specific codes for this code are the following:

• O00.101: Right tubal pregnancy with intrauterine pregnancy
• O00.102: Left tubal pregnancy with intrauterine pregnancy
• O00.109: Unspecified tubal pregnancy without intrauterine pregnancy
• O00.111: Right tubal pregnancy with intrauterine pregnancy
• O00.112: Left tubal pregnancy with intrauterine pregnancy
• O00.119: Unspecified tubal pregnancy with intrauterine pregnancy

O00.2: Ovarian pregnancy

An ectopic pregnancy in which the fertilized egg implants on the ovary.

Related, more specific codes for O00.2 are the following:

• O00.201: Right ovarian pregnancy without intrauterine pregnancy
• O00.202: Left ovarian pregnancy without intrauterine pregnancy
• O00.209: Unspecified ovarian pregnancy without intrauterine pregnancy
• O00.211: Right ovarian pregnancy with intrauterine pregnancy
• O00.212: Left ovarian pregnancy with intrauterine pregnancy
• O00.219: Unspecified ovarian pregnancy with intrauterine pregnancy

O00.8: Other ectopic pregnancy

This code is used for less common forms of ectopic pregnancies, such as cervical or intraligamentary pregnancies.

Related, more specific codes for "Other ectopic pregnancy" are the following:

• O00.80: Other ectopic pregnancy without intrauterine pregnancy
• O00.81: Other ectopic pregnancy with intrauterine pregnancy

O00.9: Ectopic pregnancy, unspecified

When the location of the ectopic pregnancy is not specified or known.

Related, more specific codes for this code are the following:

• O00.90: Unspecified ectopic pregnancy without intrauterine pregnancy
• O00.91: Unspecified ectopic pregnancy with intrauterine pregnancy

Which ectopic pregnancy ICD codes are billable?

All of the specific codes are valid and billable.

Clinical information

• Ectopic pregnancies, which are pregnancies in pelvic organs like the fallopian tube, cervix, etc., typically manifest with unilateral pelvic pain and spotting or active vaginal bleeding.
• Some patients may experience referred shoulder pain due to diaphragmatic irritation from a ruptured ectopic pregnancy causing intraperitoneal bleeding.
• A history of prior ectopic pregnancy significantly increases the risk of recurrence.
• Pelvic inflammatory disease (PID), often due to chlamydia or gonorrhea infections, can damage the fallopian tubes, predisposing to ectopic implantation.
• Surgical history, particularly tubal surgery or procedures affecting the pelvic anatomy, can contribute.
• Assisted reproductive technologies, such as IVF, are associated with a higher incidence of ectopic pregnancies.

• Transvaginal ultrasound is the preferred diagnostic modality to visualize the location of the pregnancy.
• Serial quantitative blood tests for human chorionic gonadotropin (hCG) are used to assess the viability of the pregnancy and can suggest an ectopic pregnancy if levels rise abnormally.
• The lack of an intrauterine gestational sac on ultrasound combined with a positive pregnancy test is highly suggestive of an ectopic pregnancy.

• Methotrexate therapy is an option for stable patients with unruptured ectopic pregnancies and specific criteria.
• Surgical intervention, typically via laparoscopy, is required for unstable patients who may experience associated complications, suspected tubal rupture, or when medical management is contraindicated or unsuccessful.
• Rhesus (Rh) immunoglobulin is administered to Rh-negative women to prevent Rh sensitization.

• Rupture of an ectopic pregnancy can lead to life-threatening hemorrhage and is a medical emergency.
• Infertility can result from damage to the fallopian tubes or their removal during treatment.

Synonyms include

• Tubal pregnancy
• Non-uterine pregnancy
• Extrauterine pregnancy
• Cervical pregnancy
• Abdominal pregnancy
