Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to O00: its own notes plus those printed at block O00-O08 and Chapter 15. A note printed at a category, block or chapter applies to every code under it.
Includes
Further defines, or gives examples of, the content of the category.
- ruptured ectopic pregnancy
Excludes1
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
- supervision of normal pregnancy (Z34.-)
Excludes2
Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.
Use Additional Code
Add a second code, after this one, to fully describe the condition.
- code from category O08 to identify any associated complication
- code, if applicable, from category Z3A, Weeks of gestation, to identify the specific week of the pregnancy, if known.

Clinical InformationClinical
Pregnancy, Ectopic
a potentially life-threatening condition in which embryo implantation occurs outside the cavity of the uterus. most ectopic pregnancies (>96%) occur in the fallopian tubes, known as tubal pregnancy. they can be in other locations, such as uterine cervix; ovary; and abdominal cavity (pregnancy, abdominal).
Patient EducationClinical
Ectopic Pregnancy
The uterus, or womb, is the place where a fetus grows during pregnancy. In an ectopic pregnancy, the fertilized egg grows in the wrong place outside the uterus. It usually occurs in the fallopian tubes. These tubes carry eggs from the ovaries to the uterus.

Code HistoryHistory
Questions About O00Overview
What is the ICD-10 code for ectopic pregnancy?
O00 is the ICD-10-CM category for ectopic pregnancy, but it is a non-billable header: claims need a more specific code from this category, listed on this page.
Is O00 (Ectopic pregnancy) a billable code?
No. This is a category header that groups the codes for ectopic pregnancy, and headers cannot be submitted on claims. Claims for ectopic pregnancy need a more specific code from this category, such as O00.00, O00.01, and O00.101.
Can O00 be reported with a code from O31.1?
Not as a rule. The Excludes1 note at block O00-O08, which applies to O00, lists "continuing pregnancy in multiple gestation after abortion of one fetus or more (O31.1-, O31.3-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
Does O00 need an additional code?
When the condition applies, yes. The Use Additional Code note reads: code from category O08 to identify any associated complication. The additional code is reported after O00.
