About 04104K4

04104K4 is the ICD-10-PCS code for a bypass procedure on the abdominal aorta using a percutaneous endoscopic approach with nonautologous tissue substitute (qualifier: left renal 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 Aorta-renal bypass, the ICD-9-CM procedure title it maps to (39.24).

For a different body part, codes include 04134K4 (hepatic artery), 04144K4 (splenic artery), 041C4K4 (right common iliac artery) and 041D4K4 (left common iliac artery).

The same procedure with a different approach is coded 04100K4 (open).

With a different device, use 0410494 (autologous venous tissue), 04104A4 (autologous arterial tissue), 04104J4 (synthetic substitute) and 04104Z4 (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 268 (Aortic and Heart Assist Procedures Except Pulsation Balloon with MCC), DRG 269 (Aortic and Heart Assist Procedures Except Pulsation Balloon without MCC), DRG 656 (Kidney and Ureter Procedures for Neoplasm with MCC), DRG 657 (Kidney and Ureter Procedures for Neoplasm with CC), DRG 658 (Kidney and Ureter Procedures for Neoplasm without CC/MCC) and DRG 659 (Kidney and Ureter Procedures for Non-Neoplasm with MCC), under the surgical categories “Aortic and Heart Assist Procedures Except Pulsation Balloon”, “”, “Kidney and Ureter Procedures for Non-Neoplasm” and 2 more.

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