7th characters

7th characters for O32 defined here

One of the following 7th characters is to be assigned to each code under category O32. 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 O32 that has a 7th character of 1 through 9.
