About 0WHK33Z

0WHK33Z is the ICD-10-PCS code for a insertion procedure on the upper back using a percutaneous approach with infusion device. In ICD-10-PCS, insertion means putting in a nonbiological appliance that monitors, assists, performs, or prevents a physiological function but does not physically take the place of a body part.

In plain terms, this corresponds to other incision of skin and subcutaneous tissue, the ICD-9-CM procedure title it maps to (86.09).

For a different body part, codes include 0WH033Z (head), 0WH133Z (cranial cavity), 0WH233Z (face), 0WH333Z (oral cavity and throat), 0WH433Z (upper jaw), 0WH533Z (lower jaw) and 16 more.

The same procedure with a different approach is coded 0WHK03Z (open) and 0WHK43Z (percutaneous endoscopic).

With a different device, use 0WHK31Z (radioactive element) and 0WHK3YZ (other device).

It is a non-O.R. procedure that is part of the MS-DRG logic for DRG 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC) and DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), under the surgical category “Other Skin, Subcutaneous Tissue and Breast Procedures”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
