About 0CX5XZZ

0CX5XZZ is the ICD-10-PCS code for a transfer procedure on the upper gingiva using an external approach. In ICD-10-PCS, transfer means moving, without taking out, all or a portion of a body part to another location to take over the function of all or a portion of a body part.

In plain terms, this corresponds to attachment of pedicle or flap graft to lip and mouth, the ICD-9-CM procedure title it maps to (27.57).

For a different body part, codes include 0CX0XZZ (upper lip), 0CX1XZZ (lower lip), 0CX3XZZ (soft palate), 0CX4XZZ (buccal mucosa), 0CX6XZZ (lower gingiva) and 0CX7XZZ (tongue).

The same procedure with a different approach is coded 0CX50ZZ (open).

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 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC), DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC) and DRG 907 (Other O.R. Procedures for Injuries with MCC), under the surgical categories “Mouth Procedures”, “Other Skin, Subcutaneous Tissue and Breast Procedures”, “Other O.R. Procedures for Injuries” and 1 more.

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