About ICD-10-CM O02
ICD-10-CM code O02 represents Other abnormal products of conception. This is a non-billable header code in the Pregnancy, Childbirth, and Puerperium chapter (block O02). The 2026 edition of ICD-10-CM O02 became effective on October 1, 2025. Non-billable codes cannot be used as a primary or secondary diagnosis on a claim, use a more specific child code instead.
Coding Tips for O02
Specialist guidance from the PayerReady Medical Coding Team. Specificity warnings, HCC capture rules, sequencing notes.
Most O codes require a 7th character indicating trimester (1 = first, 2 = second, 3 = third). Some require fetus identification character. Code O09 (supervision of high-risk pregnancy) is required as a secondary code when applicable.
Type 1 Excludes
Pure excludes, these codes can never be coded together with O02. The conditions are mutually exclusive (e.g., congenital vs acquired forms).
- papyraceous fetus (O31.0-)
Use Additional Code
When coding O02, also report these additional codes when applicable.
- code from category O08 to identify any associated complication.
