About 0W8NXZZ

0W8NXZZ is the ICD-10-PCS code for a division procedure on the perineum, female using an external approach. In ICD-10-PCS, division means cutting into a body part, without draining fluids and/or gases from the body part, in order to separate or transect a body part.

In plain terms, this corresponds to episiotomy, the ICD-9-CM procedure title it maps to (73.6).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
