About 0HCW7ZZ

0HCW7ZZ is the ICD-10-PCS code for a extirpation procedure on the right nipple using a via natural or artificial opening 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 0HCT7ZZ (right breast), 0HCU7ZZ (left breast), 0HCV7ZZ (bilateral breast) and 0HCX7ZZ (left nipple).

The same procedure with a different approach is coded 0HCW0ZZ (open), 0HCW3ZZ (percutaneous), 0HCW8ZZ (via natural or artificial opening endoscopic) and 0HCWXZZ (external).

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.
