About 07WK4YZ

07WK4YZ is the ICD-10-PCS code for a revision procedure on the thoracic duct using a percutaneous endoscopic 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 07WL4YZ (cisterna chyli), 07WM4YZ (thymus), 07WN4YZ (lymphatic) and 07WP4YZ (spleen).

The same procedure with a different approach is coded 07WK0YZ (open) and 07WK3YZ (percutaneous).

With a different device, use 07WK40Z (drainage device), 07WK43Z (infusion device), 07WK47Z (autologous tissue substitute), 07WK4CZ (extraluminal device), 07WK4DZ (intraluminal device), 07WK4JZ (synthetic substitute) and 1 more.

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It was added in FY2018, effective October 1, 2017.
