About 0C933ZZ

0C933ZZ is the ICD-10-PCS code for a drainage procedure on the soft palate using a percutaneous 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 other miscellaneous procedures, the ICD-9-CM procedure title it maps to (99.99).

For a different body part, codes include 0C903ZZ (upper lip), 0C913ZZ (lower lip), 0C923ZZ (hard palate), 0C943ZZ (buccal mucosa), 0C953ZZ (upper gingiva), 0C963ZZ (lower gingiva) and 18 more.

The same procedure with a different approach is coded 0C930ZZ (open) and 0C93XZZ (external).

With a different device, use 0C9330Z (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.
