O03.9 — Complete or unspecified spontaneous abortion without complication
O03.9 is a billable, specific ICD-10-CM code for complete or unspecified spontaneous abortion without complication. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Miscarriage NOS
- Spontaneous abortion NOS
Other codes that can never be billed with O03.9
These codes carry an Excludes1 note pointing at O03.9. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading O03.9 alone.
- O22Venous complications and hemorrhoids in pregnancy
Risk adjustment
O03.9 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 O03.9 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 O03.9.
- Abortion(complete) (spontaneous)
- Miscarriage
- Threatened›abortion›with subsequent abortion
