About 03HM33Z
03HM33Z is the ICD-10-PCS code for a insertion procedure on the right external carotid 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), 03H433Z (left subclavian artery), 03H533Z (right axillary artery) and 23 more.
The same procedure with a different approach is coded 03HM03Z (open) and 03HM43Z (percutaneous endoscopic).
With a different device, use 03HM3DZ (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.
