About 04HB03Z
04HB03Z is the ICD-10-PCS code for a insertion procedure on the inferior 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), 04H503Z (superior mesenteric artery) and 24 more.
The same procedure with a different approach is coded 04HB33Z (percutaneous) and 04HB43Z (percutaneous endoscopic).
With a different device, use 04HB0DZ (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.
