About 07WN43Z
07WN43Z is the ICD-10-PCS code for a revision procedure on the lymphatic 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 incision of lymphatic structures, the ICD-9-CM procedure title it maps to (40.0).
For a different body part, codes include 07WK43Z (thoracic duct), 07WL43Z (cisterna chyli), 07WM43Z (thymus) and 07WP43Z (spleen).
The same procedure with a different approach is coded 07WN03Z (open), 07WN33Z (percutaneous) and 07WNX3Z (external).
With a different device, use 07WN40Z (drainage device), 07WN47Z (autologous tissue substitute), 07WN4CZ (extraluminal device), 07WN4DZ (intraluminal device), 07WN4JZ (synthetic substitute), 07WN4KZ (nonautologous tissue 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”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
