Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to O02: 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.
Excludes1
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
- papyraceous fetus (O31.0-)
- 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.

Health Problems in Pregnancy
A health problem in pregnancy is any disease or condition that could affect your health or the health of your fetus. Some health problems may make it more likely that you will have a high-risk pregnancy. A high-risk pregnancy is one in which you, your fetus, or both are at higher risk for health problems than in a typical pregnancy.

Code HistoryHistory
Questions About O02Overview
What is the ICD-10 code for other abnormal products of conception?
O02 is the ICD-10-CM category for other abnormal products of conception, but it is a non-billable header: claims need a more specific code from this category, listed on this page.
Is O02 (Other abnormal products of conception) a billable code?
No. This is a category header that groups the codes for other abnormal products of conception, and headers cannot be submitted on claims. Claims for other abnormal products of conception need a more specific code from this category, such as O02.0, O02.1, and O02.81.
Can O02 be reported with a code from O31.0?
Not as a rule. The Excludes1 note on O02 lists "papyraceous fetus (O31.0-)". 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 O02 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 O02.
