About 03HK0MZ

03HK0MZ is the ICD-10-PCS code for a insertion procedure on the right internal carotid artery using an open approach with stimulator lead. 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 implantation or replacement of carotid sinus stimulation lead(s) only, the ICD-9-CM procedure title it maps to (39.82).

For a different body part, codes include 03HL0MZ (left internal carotid artery).

The same procedure with a different approach is coded 03HK3MZ (percutaneous) and 03HK4MZ (percutaneous endoscopic).

With a different device, use 03HK03Z (infusion device) and 03HK0DZ (intraluminal device).

It is an operating-room procedure in the MS-DRG logic for 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 category “Other Vascular Procedures”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
