About 0CR637Z
0CR637Z is the ICD-10-PCS code for a replacement procedure on the lower gingiva using a percutaneous approach with autologous 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 0CR037Z (upper lip), 0CR137Z (lower lip), 0CR237Z (hard palate), 0CR337Z (soft palate), 0CR437Z (buccal mucosa), 0CR537Z (upper gingiva) and 4 more.
The same procedure with a different approach is coded 0CR607Z (open) and 0CR6X7Z (external).
With a different device, use 0CR63JZ (synthetic substitute) and 0CR63KZ (nonautologous tissue 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.
