About 0CQX0Z2

0CQX0Z2 is the ICD-10-PCS code for a repair procedure on the lower tooth using an open approach (qualifier: all). In ICD-10-PCS, repair means restoring, to the extent possible, a body part to its normal anatomic structure and function.

In plain terms, this corresponds to other dental restoration, the ICD-9-CM procedure title it maps to (23.49).

For a different body part, codes include 0CQW0Z2 (upper tooth).

The same procedure with a different approach is coded 0CQXXZ2 (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.
