About 03HT4DZ
03HT4DZ is the ICD-10-PCS code for a insertion procedure on the left temporal artery using a percutaneous endoscopic approach with intraluminal 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).
For a different body part, codes include 03H04DZ (right internal mammary artery), 03H14DZ (left internal mammary artery), 03H24DZ (innominate artery), 03H34DZ (right subclavian artery), 03H44DZ (left subclavian artery), 03H54DZ (right axillary artery) and 23 more.
The same procedure with a different approach is coded 03HT0DZ (open) and 03HT3DZ (percutaneous).
With a different device, use 03HT43Z (infusion device).
It is an operating-room procedure in the MS-DRG logic for DRG 143 (Other Ear, Nose, Mouth and Throat O.R. Procedures with MCC), DRG 144 (Other Ear, Nose, Mouth and Throat O.R. Procedures with CC), DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), DRG 252 (Other Vascular Procedures with MCC), DRG 253 (Other Vascular Procedures with CC) and DRG 254 (Other Vascular Procedures without CC/MCC), under the surgical categories “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Other Vascular Procedures”, “Lymphoma and Leukemia with Major O.R. Procedures” and 3 more.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
