About 07WL4DZ

07WL4DZ is the ICD-10-PCS code for a revision procedure on the cisterna chyli using a percutaneous endoscopic approach with intraluminal 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 07WK4DZ (thoracic duct) and 07WN4DZ (lymphatic).

The same procedure with a different approach is coded 07WL0DZ (open), 07WL3DZ (percutaneous) and 07WLXDZ (external).

With a different device, use 07WL40Z (drainage device), 07WL43Z (infusion device), 07WL47Z (autologous tissue substitute), 07WL4CZ (extraluminal device), 07WL4JZ (synthetic substitute), 07WL4KZ (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.
