About 06120AY

06120AY is the ICD-10-PCS code for a bypass procedure on the gastric vein using an open 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 intra-abdominal venous shunt, the ICD-9-CM procedure title it maps to (39.1).

For a different body part, codes include 06100AY (inferior vena cava), 06110AY (splenic vein), 06130AY (esophageal vein), 06140AY (hepatic vein), 06150AY (superior mesenteric vein), 06160AY (inferior mesenteric vein) and 16 more.

The same procedure with a different approach is coded 06124AY (percutaneous endoscopic).

With a different device, use 061207Y (autologous tissue substitute), 061209Y (autologous venous tissue), 06120JY (synthetic substitute), 06120KY (nonautologous tissue substitute) and 06120ZY (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) and DRG 272 (Other Major Cardiovascular Procedures without CC/MCC), under the surgical category “Other Major Cardiovascular Procedures”.

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