About 0CTX0Z1
0CTX0Z1 is the ICD-10-PCS code for a resection procedure on the lower tooth using an open approach (qualifier: multiple). In ICD-10-PCS, resection means cutting out or off, without replacement, all of a body part.
In plain terms, this corresponds to other surgical extraction of tooth, the ICD-9-CM procedure title it maps to (23.19).
For a different body part, codes include 0CTW0Z1 (upper tooth).
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.
