About 021V4AR

021V4AR is the ICD-10-PCS code for a bypass procedure on the superior vena cava using a percutaneous endoscopic approach with autologous arterial tissue (qualifier: left pulmonary artery). 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 Caval-pulmonary artery anastomosis, the ICD-9-CM procedure title it maps to (39.21).

For a different body part, codes include 02164AR (right atrium), 02174AR (left atrium), 021K4AR (right ventricle), 021L4AR (left ventricle), 021W4AR (thoracic aorta, descending) and 021X4AR (thoracic aorta, ascending/arch).

The same procedure with a different approach is coded 021V0AR (open).

With a different device, use 021V48R (zooplastic tissue), 021V49R (autologous venous tissue), 021V4JR (synthetic substitute), 021V4KR (nonautologous tissue substitute) and 021V4ZR (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.
