About 04WY4CZ

04WY4CZ is the ICD-10-PCS code for a revision procedure on the lower artery using a percutaneous endoscopic approach with extraluminal 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 vessel, lower limb arteries, the ICD-9-CM procedure title it maps to (38.08).

The same procedure with a different approach is coded 04WY0CZ (open), 04WY3CZ (percutaneous) and 04WYXCZ (external).

With a different device, use 04WY40Z (drainage device), 04WY42Z (monitoring device), 04WY43Z (infusion device), 04WY47Z (autologous tissue substitute), 04WY4DZ (intraluminal device), 04WY4JZ (synthetic substitute) and 2 more.

It is an operating-room procedure in the MS-DRG logic for DRG 252 (Other Vascular Procedures with MCC), DRG 253 (Other Vascular Procedures with CC), DRG 254 (Other Vascular Procedures without CC/MCC), DRG 628 (Other Endocrine, Nutritional and Metabolic O.R. Procedures with MCC or Insertion of Antibiotic-eluting Bone Void Filler), DRG 629 (Other Endocrine, Nutritional and Metabolic O.R. Procedures with CC) and DRG 630 (Other Endocrine, Nutritional and Metabolic O.R. Procedures without CC/MCC), under the surgical categories “Other Vascular Procedures”, “Other Endocrine, Nutritional and Metabolic O.R. Procedures”, “Lymphoma and Leukemia with Major O.R. Procedures” and 3 more.

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