Questions About O00.4Overview
What is the ICD-10 code for cervical ectopic pregnancy?
O00.4 (sometimes written as O004) is the ICD-10-CM category for cervical ectopic pregnancy, but it is a non-billable header: claims need a more specific code from this category, listed on this page.
Is O00.4 (Ectopic pregnancy) a billable code?
No. This is a category header that groups the codes for cervical ectopic pregnancy, and headers cannot be submitted on claims. Claims for cervical ectopic pregnancy need a more specific code from this category, such as O00.41 and O00.42.
Can O00.4 be reported with a code from O31.1?
Not as a rule. The Excludes1 note at block O00-O08, which applies to O00.4, 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).
