About 0CR50KZ

0CR50KZ is the ICD-10-PCS code for a replacement procedure on the upper gingiva using an open approach with nonautologous tissue substitute. In ICD-10-PCS, replacement means putting in or on biological or synthetic material that physically takes the place and/or function of all or 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 0CR00KZ (upper lip), 0CR10KZ (lower lip), 0CR20KZ (hard palate), 0CR30KZ (soft palate), 0CR40KZ (buccal mucosa), 0CR60KZ (lower gingiva) and 9 more.

The same procedure with a different approach is coded 0CR53KZ (percutaneous) and 0CR5XKZ (external).

With a different device, use 0CR507Z (autologous tissue substitute) and 0CR50JZ (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.
