About 021V49Q
021V49Q is the ICD-10-PCS code for a bypass procedure on the superior vena cava using a percutaneous endoscopic approach with autologous venous tissue (qualifier: right 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 021649Q (right atrium), 021749Q (left atrium), 021K49Q (right ventricle), 021L49Q (left ventricle), 021W49Q (thoracic aorta, descending) and 021X49Q (thoracic aorta, ascending/arch).
The same procedure with a different approach is coded 021V09Q (open).
With a different device, use 021V48Q (zooplastic tissue), 021V4AQ (autologous arterial tissue), 021V4JQ (synthetic substitute), 021V4KQ (nonautologous tissue substitute) and 021V4ZQ (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.
