About 0YM00ZZ
0YM00ZZ is the ICD-10-PCS code for a reattachment procedure on the right buttock using an open approach. In ICD-10-PCS, reattachment means putting back in or on all or a portion of a separated body part to its normal location or other suitable location.
In plain terms, this corresponds to other repair and reconstruction of skin and subcutaneous tissue, the ICD-9-CM procedure title it maps to (86.89).
For a different body part, codes include 0YM10ZZ (left buttock), 0YM20ZZ (right hindquarter), 0YM30ZZ (left hindquarter), 0YM40ZZ (bilateral hindquarter), 0YM50ZZ (right inguinal region), 0YM60ZZ (left inguinal region) and 24 more.
It is an operating-room procedure in the MS-DRG logic for 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), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Other Skin, Subcutaneous Tissue and Breast Procedures” and “Other O.R. Procedures for Injuries”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
