About 07YM0Z2
07YM0Z2 is the ICD-10-PCS code for a transplantation procedure on the thymus using an open approach (qualifier: zooplastic). In ICD-10-PCS, transplantation means putting in or on all or a portion of a living body part taken from another individual or animal to physically take the place and/or function of all or a portion of a similar body part.
In plain terms, this corresponds to transplantation of thymus, the ICD-9-CM procedure title it maps to (07.94).
For a different body part, codes include 07YP0Z2 (spleen).
It is an operating-room procedure in the MS-DRG logic for DRG 163 (Major Chest Procedures with MCC), DRG 164 (Major Chest Procedures with CC), DRG 165 (Major Chest Procedures without CC/MCC), DRG 628 (Other Endocrine, Nutritional and Metabolic O.R. Procedures with MCC or Insertion of Antibiotic-eluting Bone Void Filler), DRG 629 (Other Endocrine, Nutritional and Metabolic O.R. Procedures with CC) and DRG 630 (Other Endocrine, Nutritional and Metabolic O.R. Procedures without CC/MCC), under the surgical categories “Major Chest Procedures”, “Other Endocrine, Nutritional and Metabolic O.R. Procedures”, “Other O.R. Procedures of the Blood and Blood Forming Organs” and 2 more.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
