About 04H002Z

04H002Z is the ICD-10-PCS code for a insertion procedure on the abdominal aorta using an open approach with monitoring 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 insertion of intra-aneurysm sac pressure monitoring device (intraoperative), the ICD-9-CM procedure title it maps to (00.58).

For a different body part, codes include 04HY02Z (lower artery).

The same procedure with a different approach is coded 04H032Z (percutaneous) and 04H042Z (percutaneous endoscopic).

With a different device, use 04H003Z (infusion device) and 04H00DZ (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.
