About 07WL0YZ

07WL0YZ is the ICD-10-PCS code for a revision procedure on the cisterna chyli using an open approach with other 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 07WK0YZ (thoracic duct), 07WM0YZ (thymus), 07WN0YZ (lymphatic) and 07WP0YZ (spleen).

The same procedure with a different approach is coded 07WL3YZ (percutaneous) and 07WL4YZ (percutaneous endoscopic).

With a different device, use 07WL00Z (drainage device), 07WL03Z (infusion device), 07WL07Z (autologous tissue substitute), 07WL0CZ (extraluminal device), 07WL0DZ (intraluminal device), 07WL0JZ (synthetic 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”.
