About 021V49S

021V49S 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 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 total repair of total anomalous pulmonary venous connection, the ICD-9-CM procedure title it maps to (35.82).

For a different body part, codes include 021749S (left atrium).

The same procedure with a different approach is coded 021V09S (open).

With a different device, use 021V48S (zooplastic tissue), 021V4AS (autologous arterial tissue), 021V4JS (synthetic substitute), 021V4KS (nonautologous tissue substitute) and 021V4ZS (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 228 (Other Cardiothoracic Procedures with MCC), DRG 229 (Other Cardiothoracic Procedures without MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC), DRG 909 (Other O.R. Procedures for Injuries without CC/MCC) and DRG 957 (Other O.R. Procedures for Multiple Significant Trauma with MCC), under the surgical categories “Other Cardiothoracic Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

It was added in FY2017, effective October 1, 2016.
