About 03HY42Z

03HY42Z is the ICD-10-PCS code for a insertion procedure on the upper 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, upper limb vessels, the ICD-9-CM procedure title it maps to (38.03).

The same procedure with a different approach is coded 03HY02Z (open) and 03HY32Z (percutaneous).

With a different device, use 03HY43Z (infusion device), 03HY4DZ (intraluminal device) and 03HY4YZ (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) and DRG 254 (Other Vascular Procedures without CC/MCC), under the surgical category “Other Vascular Procedures”.

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