About 0CU6XKZ

0CU6XKZ is the ICD-10-PCS code for a supplement procedure on the lower gingiva using an external approach with nonautologous tissue substitute. In ICD-10-PCS, supplement means putting in or on biological or synthetic material that physically reinforces and/or augments the function of a portion of a body part.

In plain terms, this corresponds to Gingivoplasty, the ICD-9-CM procedure title it maps to (24.2).

For a different body part, codes include 0CU0XKZ (upper lip), 0CU1XKZ (lower lip), 0CU2XKZ (hard palate), 0CU3XKZ (soft palate), 0CU4XKZ (buccal mucosa), 0CU5XKZ (upper gingiva) and 2 more.

The same procedure with a different approach is coded 0CU60KZ (open) and 0CU63KZ (percutaneous).

With a different device, use 0CU6X7Z (autologous tissue substitute) and 0CU6XJZ (synthetic substitute).

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.
