About 0HHT3NZ

0HHT3NZ is the ICD-10-PCS code for a insertion procedure on the right breast using a percutaneous 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 0HHU3NZ (left breast), 0HHV3NZ (bilateral breast), 0HHW3NZ (right nipple) and 0HHX3NZ (left nipple).

The same procedure with a different approach is coded 0HHT0NZ (open), 0HHT7NZ (via natural or artificial opening) and 0HHT8NZ (via natural or artificial opening endoscopic).

With a different device, use 0HHT31Z (radioactive element) and 0HHT3YZ (other device).

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.
