About 07WN4KZ

07WN4KZ is the ICD-10-PCS code for a revision procedure on the lymphatic using a percutaneous endoscopic approach with nonautologous tissue substitute. 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 lymphatic structures, the ICD-9-CM procedure title it maps to (40.9).

For a different body part, codes include 07WK4KZ (thoracic duct) and 07WL4KZ (cisterna chyli).

The same procedure with a different approach is coded 07WN0KZ (open), 07WN3KZ (percutaneous) and 07WNXKZ (external).

With a different device, use 07WN40Z (drainage device), 07WN43Z (infusion device), 07WN47Z (autologous tissue substitute), 07WN4CZ (extraluminal device), 07WN4DZ (intraluminal device), 07WN4JZ (synthetic substitute) and 1 more.

It is an operating-room procedure in the MS-DRG logic for 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), DRG 804 (Other O.R. Procedures of the Blood and Blood Forming Organs without CC/MCC), DRG 820 (Lymphoma and Leukemia with Major O.R. Procedures with MCC), DRG 821 (Lymphoma and Leukemia with Major O.R. Procedures with CC) and DRG 822 (Lymphoma and Leukemia with Major O.R. Procedures without CC/MCC), under the surgical categories “Other O.R. Procedures of the Blood and Blood Forming Organs”, “Lymphoma and Leukemia with Major O.R. Procedures”, “Myeloproliferative Disorders or Poorly Differentiated Neoplasms with Major O.R. Procedures” and 1 more.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
