About 03H433Z
03H433Z is the ICD-10-PCS code for a insertion procedure on the left subclavian artery using a percutaneous approach with infusion 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).
For a different body part, codes include 03H033Z (right internal mammary artery), 03H133Z (left internal mammary artery), 03H233Z (innominate artery), 03H333Z (right subclavian artery), 03H533Z (right axillary artery), 03H633Z (left axillary artery) and 23 more.
The same procedure with a different approach is coded 03H403Z (open) and 03H443Z (percutaneous endoscopic).
With a different device, use 03H43DZ (intraluminal 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.
