About 0HWT30Z

0HWT30Z is the ICD-10-PCS code for a revision procedure on the right breast using a percutaneous approach with drainage device. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.

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 0HWU30Z (left breast).

The same procedure with a different approach is coded 0HWT00Z (open), 0HWT70Z (via natural or artificial opening) and 0HWT80Z (via natural or artificial opening endoscopic).

With a different device, use 0HWT37Z (autologous tissue substitute), 0HWT3JZ (synthetic substitute), 0HWT3KZ (nonautologous tissue substitute), 0HWT3NZ (tissue expander) and 0HWT3YZ (other 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.
