About 0H9W7ZX

0H9W7ZX is the ICD-10-PCS code for a drainage procedure on the right nipple using a via natural or artificial opening approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to closed [percutaneous] [needle] biopsy of breast, the ICD-9-CM procedure title it maps to (85.11).

For a different body part, codes include 0H9T7ZX (right breast), 0H9U7ZX (left breast), 0H9V7ZX (bilateral breast) and 0H9X7ZX (left nipple).

The same procedure with a different approach is coded 0H9W0ZX (open), 0H9W3ZX (percutaneous), 0H9W8ZX (via natural or artificial opening endoscopic) and 0H9WXZX (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.
