2025 ICD-10-CM code O00.9

Unspecified ectopic pregnancy. This code is used when the specific location of the ectopic pregnancy is not documented.

Codes from chapter O00-O9A are for use only on maternal records, never on newborn records. Use additional code, if applicable, from category Z3A, Weeks of gestation, to identify the specific week of the pregnancy, if known.If a complication of pregnancy is present, an additional code from category O08 should also be assigned.

Medical necessity for the treatment of an ectopic pregnancy is established by the presence of an ectopic pregnancy confirmed by diagnostic testing.The potentially life-threatening nature of an ectopic pregnancy necessitates appropriate intervention, which may include medication or surgery.

The clinician is responsible for documenting the diagnosis of an ectopic pregnancy, including the location if known, and any associated complications. This includes a thorough physical exam, imaging studies (such as ultrasound), and laboratory tests (such as beta-hCG levels). The clinician is also responsible for determining the appropriate treatment, which may include medication or surgery.

IMPORTANT:Use more specific codes from category O00 if the location of the ectopic pregnancy is known (e.g., O00.0 for abdominal pregnancy, O00.1 for tubal pregnancy).Use additional code from category O08 to identify any associated complications.

In simple words: An ectopic pregnancy is a pregnancy that develops outside of the womb, usually in a fallopian tube. This particular code is used when the exact location isn't known.

An ectopic pregnancy is a pregnancy that occurs outside of the uterus.The most common location is the fallopian tube, but it can occur in other locations such as the ovary, abdomen, or cervix. This code is used when the specific location is not documented or is unknown.

Example 1: A 28-year-old female presents to the emergency room with lower abdominal pain and vaginal bleeding.Ultrasound reveals an ectopic pregnancy, but the exact location cannot be determined.The code O00.9 is used., A 35-year-old female with a history of pelvic inflammatory disease presents to her physician with abdominal pain.A pregnancy test is positive, and an ultrasound shows a gestational sac outside the uterus, but the location is unclear.The code O00.9 is used., A woman undergoes surgery for an ectopic pregnancy. The operative report states "ectopic pregnancy" but doesn't specify the location. The code O00.9 would be used in this case.

Documentation should include details of the patient's symptoms (such as abdominal pain, vaginal bleeding), results of diagnostic tests (such as ultrasound, beta-hCG levels), location of the ectopic pregnancy if known, and treatment provided (such as medication, surgery). Documentation of weeks of gestation is also recommended.
