About 051T0AY

051T0AY is the ICD-10-PCS code for a bypass procedure on the right face vein using an open approach with autologous arterial tissue (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 (peripheral) vascular shunt or bypass, the ICD-9-CM procedure title it maps to (39.29).

For a different body part, codes include 05100AY (azygos vein), 05110AY (hemiazygos vein), 05130AY (right innominate vein), 05140AY (left innominate vein), 05150AY (right subclavian vein), 05160AY (left subclavian vein) and 18 more.

The same procedure with a different approach is coded 051T4AY (percutaneous endoscopic).

With a different device, use 051T07Y (autologous tissue substitute), 051T09Y (autologous venous tissue), 051T0JY (synthetic substitute), 051T0KY (nonautologous tissue substitute) and 051T0ZY (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 252 (Other Vascular Procedures with MCC), DRG 253 (Other Vascular Procedures with CC) and DRG 254 (Other Vascular Procedures without CC/MCC), under the surgical category “Other Vascular Procedures”.

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