About 0CR407Z

0CR407Z is the ICD-10-PCS code for a replacement procedure on the buccal mucosa using an open 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 other skin graft to lip and mouth, the ICD-9-CM procedure title it maps to (27.56).

For a different body part, codes include 0CR007Z (upper lip), 0CR107Z (lower lip), 0CR207Z (hard palate), 0CR307Z (soft palate), 0CR507Z (upper gingiva), 0CR607Z (lower gingiva) and 9 more.

The same procedure with a different approach is coded 0CR437Z (percutaneous) and 0CR4X7Z (external).

With a different device, use 0CR40JZ (synthetic substitute) and 0CR40KZ (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 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.
