About 0HHT7YZ

0HHT7YZ is the ICD-10-PCS code for a insertion procedure on the right breast using a via natural or artificial opening 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 0HHU7YZ (left breast).

The same procedure with a different approach is coded 0HHT0YZ (open), 0HHT3YZ (percutaneous) and 0HHT8YZ (via natural or artificial opening endoscopic).

With a different device, use 0HHT71Z (radioactive element) and 0HHT7NZ (tissue expander).

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

It was added in FY2018, effective October 1, 2017.
