About 03HY4YZ
03HY4YZ is the ICD-10-PCS code for a insertion procedure on the upper artery using a percutaneous endoscopic approach with other 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 other operations on vessels, the ICD-9-CM procedure title it maps to (39.99).
The same procedure with a different approach is coded 03HY0YZ (open) and 03HY3YZ (percutaneous).
With a different device, use 03HY42Z (monitoring device), 03HY43Z (infusion device) and 03HY4DZ (intraluminal device).
It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.
It was added in FY2018, effective October 1, 2017.
