About 0HBU8ZZ

0HBU8ZZ is the ICD-10-PCS code for a excision procedure on the left breast using a via natural or artificial opening endoscopic approach. In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to local excision of lesion of breast, the ICD-9-CM procedure title it maps to (85.21).

For a different body part, codes include 0HBT8ZZ (right breast), 0HBV8ZZ (bilateral breast), 0HBW8ZZ (right nipple), 0HBX8ZZ (left nipple) and 0HBY8ZZ (supernumerary breast).

The same procedure with a different approach is coded 0HBU0ZZ (open), 0HBU3ZZ (percutaneous) and 0HBU7ZZ (via natural or artificial opening).

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.
