About 0HHX8NZ

0HHX8NZ is the ICD-10-PCS code for a insertion procedure on the left nipple using a via natural or artificial opening endoscopic approach with tissue expander. 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 insertion of breast tissue expander, the ICD-9-CM procedure title it maps to (85.95).

For a different body part, codes include 0HHT8NZ (right breast), 0HHU8NZ (left breast), 0HHV8NZ (bilateral breast) and 0HHW8NZ (right nipple).

The same procedure with a different approach is coded 0HHX0NZ (open), 0HHX3NZ (percutaneous) and 0HHX7NZ (via natural or artificial opening).

With a different device, use 0HHX81Z (radioactive element).

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.
