About 04H503Z
04H503Z is the ICD-10-PCS code for a insertion procedure on the superior mesenteric artery using an open 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 04H003Z (abdominal aorta), 04H103Z (celiac artery), 04H203Z (gastric artery), 04H303Z (hepatic artery), 04H403Z (splenic artery), 04H603Z (right colic artery) and 24 more.
The same procedure with a different approach is coded 04H533Z (percutaneous) and 04H543Z (percutaneous endoscopic).
With a different device, use 04H50DZ (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.
