About 07WK43Z

07WK43Z is the ICD-10-PCS code for a revision procedure on the thoracic duct 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 operations on thoracic duct, the ICD-9-CM procedure title it maps to (40.69).

For a different body part, codes include 07WL43Z (cisterna chyli), 07WM43Z (thymus), 07WN43Z (lymphatic) and 07WP43Z (spleen).

The same procedure with a different approach is coded 07WK03Z (open), 07WK33Z (percutaneous) and 07WKX3Z (external).

With a different device, use 07WK40Z (drainage device), 07WK47Z (autologous tissue substitute), 07WK4CZ (extraluminal device), 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”.
