About 07WN0YZ

07WN0YZ is the ICD-10-PCS code for a revision procedure on the lymphatic 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 incision of lymphatic structures, the ICD-9-CM procedure title it maps to (40.0).

For a different body part, codes include 07WK0YZ (thoracic duct), 07WL0YZ (cisterna chyli), 07WM0YZ (thymus) and 07WP0YZ (spleen).

The same procedure with a different approach is coded 07WN3YZ (percutaneous) and 07WN4YZ (percutaneous endoscopic).

With a different device, use 07WN00Z (drainage device), 07WN03Z (infusion device), 07WN07Z (autologous tissue substitute), 07WN0CZ (extraluminal device), 07WN0DZ (intraluminal device), 07WN0JZ (synthetic substitute) and 1 more.

It is an operating-room procedure in the MS-DRG logic for DRG 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC), DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), DRG 802 (Other O.R. Procedures of the Blood and Blood Forming Organs with MCC), DRG 803 (Other O.R. Procedures of the Blood and Blood Forming Organs with CC) and DRG 804 (Other O.R. Procedures of the Blood and Blood Forming Organs without CC/MCC), under the surgical categories “Other Skin, Subcutaneous Tissue and Breast Procedures” and “Other O.R. Procedures of the Blood and Blood Forming Organs”.
