About 03HY32Z

03HY32Z is the ICD-10-PCS code for a insertion procedure on the upper artery using a percutaneous 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 arterial catheterization, the ICD-9-CM procedure title it maps to (38.91).

The same procedure with a different approach is coded 03HY02Z (open) and 03HY42Z (percutaneous endoscopic).

With a different device, use 03HY33Z (infusion device), 03HY3DZ (intraluminal device) and 03HY3YZ (other device).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

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