About X2AL34B
X2AL34B is the ICD-10-PCS code for a assistance procedure on the left internal carotid artery using a percutaneous approach with cerebral embolic filtration, single integrated distal filter (qualifier: new technology group 11). In ICD-10-PCS, assistance means taking over a portion of a physiological function by extracorporeal means.
For a different body part, codes include X2AH34B (right common carotid artery), X2AJ34B (left common carotid artery) and X2AK34B (right internal carotid artery).
It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.
It was added in FY2026, effective October 1, 2025.
