Official coding rules

Published by CDC for FY2027. A rule attached to a category binds every code beneath it, so the rules inherited from this code's ancestors are shown with the code they come from.

Inherited from O31 Complications specific to multiple gestation

Seventh character required

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.

Excludes2 - not included here

delayed delivery of second twin, triplet, etc. (O63.2)
malpresentation of one fetus or more (O32.9)
placental transfusion syndromes (O43.0-)
