Billable / specific codeICD-10-CM

O35.9XX0 is a billable, specific ICD-10-CM code for maternal care for (suspected) fetal abnormality and damage, unspecified, not applicable or unspecified. It is valid for submission on a claim.

7th character "0" — not applicable or unspecified

One of the following 7th characters is to be assigned to each code under category O35. 7th character 0 is for single gestations and multiple gestations where the fetus is unspecified. 7th characters 1 through 9 are for cases of multiple gestations to identify the fetus for which the code applies. The appropriate code from category O30, Multiple gestation, must also be assigned when assigning a code from category O35 that has a 7th character of 1 through 9.

0: not applicable or unspecified
1: fetus 1
2: fetus 2
3: fetus 3
4: fetus 4
5: fetus 5
9: other fetus

Risk adjustment

O35.9XX0 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.
