About 0CB3XZZ

0CB3XZZ is the ICD-10-PCS code for a excision procedure on the soft palate using an external approach. In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to other excision of mouth, the ICD-9-CM procedure title it maps to (27.49).

For a different body part, codes include 0CB0XZZ (upper lip), 0CB1XZZ (lower lip), 0CB2XZZ (hard palate), 0CB4XZZ (buccal mucosa), 0CB5XZZ (upper gingiva), 0CB6XZZ (lower gingiva) and 4 more.

The same procedure with a different approach is coded 0CB30ZZ (open) and 0CB33ZZ (percutaneous).

It is an operating-room procedure in the MS-DRG logic for DRG 137 (Mouth Procedures with CC/MCC), DRG 138 (Mouth Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC), DRG 909 (Other O.R. Procedures for Injuries without CC/MCC) and DRG 957 (Other O.R. Procedures for Multiple Significant Trauma with MCC), under the surgical categories “Mouth Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

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