04100ZKBypass Abdominal Aorta to Bilateral Femoral Arteries, Open Approach

04100ZK is the ICD-10-PCS code for a bypass procedure on the abdominal aorta using an open approach (qualifier: bilateral femoral arteries). 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-iliac-femoral bypass, the ICD-9-CM procedure title it maps to (39.25).

For a different body part, codes include 041C0ZK (right common iliac artery), 041D0ZK (left common iliac artery), 041E0ZK (right internal iliac artery), 041F0ZK (left internal iliac artery), 041H0ZK (right external iliac artery), 041J0ZK (left external iliac artery) and 2 more.

The same procedure with a different approach is coded 04104ZK (percutaneous endoscopic).

With a different device, use 041009K (autologous venous tissue), 04100AK (autologous arterial tissue), 04100JK (synthetic substitute) and 04100KK (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), DRG 272 (Other Major Cardiovascular Procedures without CC/MCC), DRG 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC) and DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), under the surgical categories “Other Major Cardiovascular Procedures”, “Other Skin, Subcutaneous Tissue and Breast Procedures” and “Other O.R. Procedures for Injuries”.

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