Is O03.0 a billable ICD-10-CM code?

Yes. O03.0 is a billable, specific ICD-10-CM code and is valid for submission on a claim.

Where does O03.0 sit in the tabular list?

Pregnancy, childbirth and the puerperium (O00-O9A), in the block Pregnancy with abortive outcome (O00-O08).

What cannot be coded together with O03.0?

O03.0 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

O03.0

O03.0 — Genital tract and pelvic infection following incomplete spontaneous abortion

Billable / specific codeICD-10-CM

O03.0 is a billable, specific ICD-10-CM code for genital tract and pelvic infection following incomplete spontaneous abortion. It is valid for submission on a claim.

Excludes1 — never code together

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

sepsis following incomplete spontaneous abortion (O03.37)
urinary tract infection following incomplete spontaneous abortion (O03.38)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Endometritis following incomplete spontaneous abortion
Oophoritis following incomplete spontaneous abortion
Parametritis following incomplete spontaneous abortion
Pelvic peritonitis following incomplete spontaneous abortion
Salpingitis following incomplete spontaneous abortion
Salpingo-oophoritis following incomplete spontaneous abortion

Other codes that can never be billed with O03.0

These codes carry an Excludes1 note pointing at O03.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading O03.0 alone.

O07Failed attempted termination of pregnancy

Risk adjustment

O03.0 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.

How O03.0 is indexed

Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to O03.0.
