About 021V4ZP

021V4ZP is the ICD-10-PCS code for a bypass procedure on the superior vena cava using a percutaneous endoscopic approach (qualifier: pulmonary trunk). 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 02164ZP (right atrium), 02174ZP (left atrium), 021K4ZP (right ventricle), 021L4ZP (left ventricle), 021W4ZP (thoracic aorta, descending) and 021X4ZP (thoracic aorta, ascending/arch).

The same procedure with a different approach is coded 021V0ZP (open).

With a different device, use 021V48P (zooplastic tissue), 021V49P (autologous venous tissue), 021V4AP (autologous arterial tissue), 021V4JP (synthetic substitute) and 021V4KP (nonautologous tissue substitute).

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.
