About 04104Z2
04104Z2 is the ICD-10-PCS code for a bypass procedure on the abdominal aorta using a percutaneous endoscopic approach (qualifier: mesenteric artery). In ICD-10-PCS, bypass means altering the route of passage of the contents of a tubular body part.
In plain terms, this corresponds to other intra-abdominal vascular shunt or bypass, the ICD-9-CM procedure title it maps to (39.26).
For a different body part, codes include 041C4Z2 (right common iliac artery) and 041D4Z2 (left common iliac artery).
The same procedure with a different approach is coded 04100Z2 (open).
With a different device, use 0410492 (autologous venous tissue), 04104A2 (autologous arterial tissue), 04104J2 (synthetic substitute) and 04104K2 (nonautologous tissue substitute).
It is an operating-room procedure in the MS-DRG logic for DRG 270 (Other Major Cardiovascular Procedures with MCC), DRG 271 (Other Major Cardiovascular Procedures with CC) and DRG 272 (Other Major Cardiovascular Procedures without CC/MCC), under the surgical category “Other Major Cardiovascular Procedures”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
