About 04PY42Z

04PY42Z is the ICD-10-PCS code for a removal procedure on the lower artery using a percutaneous endoscopic approach with monitoring device. In ICD-10-PCS, removal means taking out or off a device from a body part.

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 04PY02Z (open), 04PY32Z (percutaneous) and 04PYX2Z (external).

With a different device, use 04PY40Z (drainage device), 04PY43Z (infusion device), 04PY47Z (autologous tissue substitute), 04PY4CZ (extraluminal device), 04PY4DZ (intraluminal device), 04PY4JZ (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.
