About 05100KY

05100KY is the ICD-10-PCS code for a bypass procedure on the azygos vein using an open approach with nonautologous tissue substitute (qualifier: upper vein). 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 intrathoracic vascular shunt or bypass, the ICD-9-CM procedure title it maps to (39.23).

For a different body part, codes include 05110KY (hemiazygos vein), 05130KY (right innominate vein), 05140KY (left innominate vein), 05150KY (right subclavian vein), 05160KY (left subclavian vein), 05170KY (right axillary vein) and 18 more.

The same procedure with a different approach is coded 05104KY (percutaneous endoscopic).

With a different device, use 051007Y (autologous tissue substitute), 051009Y (autologous venous tissue), 05100AY (autologous arterial tissue), 05100JY (synthetic substitute) and 05100ZY (no device).

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 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Other Major Cardiovascular Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

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