About 0HCT8ZZ

0HCT8ZZ is the ICD-10-PCS code for a extirpation procedure on the right breast using a via natural or artificial opening endoscopic approach. In ICD-10-PCS, extirpation means taking or cutting out solid matter from 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 0HCU8ZZ (left breast), 0HCV8ZZ (bilateral breast), 0HCW8ZZ (right nipple) and 0HCX8ZZ (left nipple).

The same procedure with a different approach is coded 0HCT0ZZ (open), 0HCT3ZZ (percutaneous) and 0HCT7ZZ (via natural or artificial opening).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

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