About 07WK4CZ

07WK4CZ is the ICD-10-PCS code for a revision procedure on the thoracic duct using a percutaneous endoscopic approach with extraluminal 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 operations on thoracic duct, the ICD-9-CM procedure title it maps to (40.69).

For a different body part, codes include 07WL4CZ (cisterna chyli) and 07WN4CZ (lymphatic).

The same procedure with a different approach is coded 07WK0CZ (open), 07WK3CZ (percutaneous) and 07WKXCZ (external).

With a different device, use 07WK40Z (drainage device), 07WK43Z (infusion device), 07WK47Z (autologous tissue substitute), 07WK4DZ (intraluminal device), 07WK4JZ (synthetic substitute), 07WK4KZ (nonautologous tissue substitute) and 1 more.

It is an operating-room procedure in the MS-DRG logic for DRG 163 (Major Chest Procedures with MCC), DRG 164 (Major Chest Procedures with CC) and DRG 165 (Major Chest Procedures without CC/MCC), under the surgical category “Major Chest Procedures”.

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