About 0H9V00Z

0H9V00Z is the ICD-10-PCS code for a drainage procedure on the bilateral breast using an open approach with drainage device. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases 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 0H9T00Z (right breast), 0H9U00Z (left breast), 0H9W00Z (right nipple) and 0H9X00Z (left nipple).

The same procedure with a different approach is coded 0H9V30Z (percutaneous), 0H9V70Z (via natural or artificial opening) and 0H9V80Z (via natural or artificial opening endoscopic).

With a different device, use 0H9V0ZZ (no device).

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.
