About 0HQU0ZZ

0HQU0ZZ is the ICD-10-PCS code for a repair procedure on the left breast using an open approach. In ICD-10-PCS, repair means restoring, to the extent possible, a body part to its normal anatomic structure and function.

In plain terms, this corresponds to other mammoplasty, the ICD-9-CM procedure title it maps to (85.89).

For a different body part, codes include 0HQT0ZZ (right breast), 0HQV0ZZ (bilateral breast), 0HQW0ZZ (right nipple), 0HQX0ZZ (left nipple) and 0HQY0ZZ (supernumerary breast).

The same procedure with a different approach is coded 0HQU3ZZ (percutaneous), 0HQU7ZZ (via natural or artificial opening) and 0HQU8ZZ (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 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC), DRG 909 (Other O.R. Procedures for Injuries without CC/MCC) and DRG 957 (Other O.R. Procedures for Multiple Significant Trauma with MCC), under the surgical categories “Breast Biopsy, Local Excision and Other Breast Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

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