Alternative wordings a physician may use in the chart for this same code.
- Biochemical pregnancy
- Chemical pregnancy
- Inappropriate level of quantitative human chorionic gonadotropin (hCG) for gestational age in early pregnancy
Risk adjustment
O02.81 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 O02.81 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 O02.81.
