About 0CCW0Z2

0CCW0Z2 is the ICD-10-PCS code for a extirpation procedure on the upper tooth using an open approach (qualifier: all). In ICD-10-PCS, extirpation means taking or cutting out solid matter from a body part.

In plain terms, this corresponds to other dental operations, the ICD-9-CM procedure title it maps to (24.99).

For a different body part, codes include 0CCX0Z2 (lower tooth).

The same procedure with a different approach is coded 0CCWXZ2 (external).

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.
