Billable / specific codeICD-10-CM

O33.7XX4 is a billable, specific ICD-10-CM code for maternal care for disproportion due to other fetal deformities, fetus 4. It is valid for submission on a claim.

7th character "4" — fetus 4

One of the following 7th characters is to be assigned to code O33.7. 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 code O33.7 with 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

Other codes that can never be billed with O33.7XX4

Risk adjustment

O33.7XX4 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.
