Ectopic Pregnancy ICD-10-CM Codes | 2023

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.
• O00.1 - Tubal pregnancy: The most common type of ectopic pregnancy, where implantation occurs in the fallopian tubes.
• O00.2 - Ovarian pregnancy: An ectopic pregnancy in which the fertilized egg implants on the ovary.
• O00.8 - Other ectopic pregnancy: This code is used for less common forms of ectopic pregnancies, such as cervical or intraligamentary pregnancies.
• O00.9 - Ectopic pregnancy, unspecified: When the location of the ectopic pregnancy is not specified or known.
• O00.91 - Ectopic pregnancy without intrauterine pregnancy: Used when there is only an ectopic pregnancy without any concurrent intrauterine pregnancy.
• O00.101 - Right tubal pregnancy without intrauterine pregnancy: A specific code for an ectopic pregnancy located in the right fallopian tube, with no intrauterine pregnancy present.
• O00.112 - Left tubal pregnancy without intrauterine pregnancy: A specific code for an ectopic pregnancy located in the left fallopian tube, with no intrauterine pregnancy present.

Clinical Information

• Ectopic pregnancies 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, 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.
