About 0H9X8ZZ

0H9X8ZZ is the ICD-10-PCS code for a drainage procedure on the left nipple using a via natural or artificial opening endoscopic approach. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to aspiration of breast, the ICD-9-CM procedure title it maps to (85.91).

For a different body part, codes include 0H9T8ZZ (right breast), 0H9U8ZZ (left breast), 0H9V8ZZ (bilateral breast) and 0H9W8ZZ (right nipple).

The same procedure with a different approach is coded 0H9X0ZZ (open), 0H9X3ZZ (percutaneous), 0H9X7ZZ (via natural or artificial opening) and 0H9XXZZ (external).

With a different device, use 0H9X80Z (drainage 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.
