About 0HCU0ZZ

0HCU0ZZ is the ICD-10-PCS code for a extirpation procedure on the left breast using an open approach. In ICD-10-PCS, extirpation means taking or cutting out solid matter from a body part.

In plain terms, this corresponds to Mastotomy, the ICD-9-CM procedure title it maps to (85.0).

For a different body part, codes include 0HCT0ZZ (right breast), 0HCV0ZZ (bilateral breast), 0HCW0ZZ (right nipple) and 0HCX0ZZ (left nipple).

The same procedure with a different approach is coded 0HCU3ZZ (percutaneous), 0HCU7ZZ (via natural or artificial opening) and 0HCU8ZZ (via natural or artificial opening endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 584 (Breast Biopsy, Local Excision and Other Breast Procedures with CC/MCC), DRG 585 (Breast Biopsy, Local Excision and Other Breast 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), DRG 630 (Other Endocrine, Nutritional and Metabolic O.R. Procedures without CC/MCC) and DRG 907 (Other O.R. Procedures for Injuries with MCC), under the surgical categories “Breast Biopsy, Local Excision and Other Breast Procedures”, “Other Endocrine, Nutritional and Metabolic O.R. Procedures”, “Other O.R. Procedures for Injuries” and 1 more.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
