About 03HT43Z
03HT43Z is the ICD-10-PCS code for a insertion procedure on the left temporal artery using a percutaneous endoscopic 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 03H043Z (right internal mammary artery), 03H143Z (left internal mammary artery), 03H243Z (innominate artery), 03H343Z (right subclavian artery), 03H443Z (left subclavian artery), 03H543Z (right axillary artery) and 23 more.
The same procedure with a different approach is coded 03HT03Z (open) and 03HT33Z (percutaneous).
With a different device, use 03HT4DZ (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.
