About 0WW643Z

0WW643Z is the ICD-10-PCS code for a revision procedure on the neck using a percutaneous endoscopic approach with infusion 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 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 0WW043Z (head), 0WW143Z (cranial cavity), 0WW243Z (face), 0WW443Z (upper jaw), 0WW543Z (lower jaw), 0WW843Z (chest wall) and 15 more.

The same procedure with a different approach is coded 0WW603Z (open), 0WW633Z (percutaneous) and 0WW6X3Z (external).

With a different device, use 0WW640Z (drainage device), 0WW641Z (radioactive element), 0WW647Z (autologous tissue substitute), 0WW64JZ (synthetic substitute), 0WW64KZ (nonautologous tissue substitute) and 0WW64YZ (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.
