About 061Q4AY

061Q4AY is the ICD-10-PCS code for a bypass procedure on the left saphenous vein using a percutaneous endoscopic approach with autologous arterial tissue (qualifier: lower 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 06104AY (inferior vena cava), 06114AY (splenic vein), 06124AY (gastric vein), 06134AY (esophageal vein), 06144AY (hepatic vein), 06154AY (superior mesenteric vein) and 16 more.

The same procedure with a different approach is coded 061Q0AY (open).

With a different device, use 061Q47Y (autologous tissue substitute), 061Q49Y (autologous venous tissue), 061Q4JY (synthetic substitute), 061Q4KY (nonautologous tissue substitute) and 061Q4ZY (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.
