About 0HHT0YZ

0HHT0YZ is the ICD-10-PCS code for a insertion procedure on the right breast using an open approach with other device. In ICD-10-PCS, insertion means putting in a nonbiological appliance that monitors, assists, performs, or prevents a physiological function but does not physically take the place of 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 0HHU0YZ (left breast).

The same procedure with a different approach is coded 0HHT3YZ (percutaneous), 0HHT7YZ (via natural or artificial opening) and 0HHT8YZ (via natural or artificial opening endoscopic).

With a different device, use 0HHT01Z (radioactive element) and 0HHT0NZ (tissue expander).

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 was added in FY2018, effective October 1, 2017.
