About 04HY42Z

04HY42Z is the ICD-10-PCS code for a insertion procedure on the lower artery using a percutaneous endoscopic approach with monitoring device. In ICD-10-PCS, insertion means putting in a nonbiological appliance that monitors, assists, performs, or prevents a physiological function but does not physically take the place of 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).

For a different body part, codes include 04H042Z (abdominal aorta).

The same procedure with a different approach is coded 04HY02Z (open) and 04HY32Z (percutaneous).

With a different device, use 04HY43Z (infusion device), 04HY4DZ (intraluminal device) and 04HY4YZ (other device).

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.
