Non-billable headerICD-10-CM

O02 is a non-billable header ICD-10-CM code for other abnormal products of conception. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

papyraceous fetus (O31.0-)

Use additional code

Add a secondary code to capture the detail described below.

code from category O08 to identify any associated complication.

Other codes that can never be billed with O02

These codes carry an Excludes1 note pointing at O02. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading O02 alone.

O02.1Missed abortion
O02.8Other specified abnormal products of conception
O36.4Maternal care for intrauterine death
O36.4XX0Maternal care for intrauterine death, not applicable or unspecified
O36.4XX1Maternal care for intrauterine death, fetus 1
O36.4XX2Maternal care for intrauterine death, fetus 2
O36.4XX3Maternal care for intrauterine death, fetus 3
O36.4XX4Maternal care for intrauterine death, fetus 4

Risk adjustment

O02 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead O02

4 child codes. Green means billable.
