About O02

O02 is the ICD-10-CM diagnosis code for other abnormal products of conception. It belongs to block O00-O08 (pregnancy with abortive outcome) and chapter 15 (pregnancy, childbirth and the puerperium). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: O02.0 (mole), O02.1 (abortion), O02.8 (conception) and O02.9 (unspecified).

Don't report O02 together with the conditions in its Excludes1 note: papyraceous fetus (O31.0-).

Use an additional code from category O08 to identify any associated complication.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
