Non-billable headerICD-10-CM

O31.8X is a non-billable header ICD-10-CM code for other complications specific to multiple gestation. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.

This code requires a 7th character

One of the following 7th characters is to be assigned to each code under category O31. 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 O31 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

O31.8X 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.

Code to one of these instead O31.8X

4 child codes. Green means billable.
