Other abnormal products of conception (O02) ICD-10-CM
The O02 code range covers other abnormal products of conception with 7 ICD-10-CM diagnosis codes. 5 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- papyraceous fetus O31.0

About the O02 Code Range
The ICD-10 code section O02 covers various types of abnormal products of conception, which are complications related to pregnancy loss or abnormal pregnancy tissue development. These codes help healthcare providers classify specific conditions such as blighted ovum, missed abortion, and abnormal hormone changes during early pregnancy.
This code range includes detailed diagnoses like O02.0 for blighted ovum (also known as carneous mole), a condition where a fertilized egg implants but does not develop into an embryo. The code O02.1 corresponds to missed abortion, often called a missed miscarriage, where the embryo or fetus has died but has not been physically expelled. Codes such as O02.81 describe abnormal levels of human chorionic gonadotropin (hCG) in early pregnancy, which is important in identifying biochemical pregnancies or molar pregnancies. Other codes, like O02.89 and O02.9, account for less specific or unspecified abnormal pregnancy tissues, including detached trophoblasts or retained products of conception. These detailed distinctions ensure precise coding for conditions affecting early pregnancy development and loss, aiding accurate diagnosis, treatment, and reporting.
