About 021748R
021748R is the ICD-10-PCS code for a bypass procedure on the left atrium using a percutaneous endoscopic approach with zooplastic 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 creation of conduit between atrium and pulmonary artery, the ICD-9-CM procedure title it maps to (35.94).
For a different body part, codes include 021648R (right atrium), 021K48R (right ventricle), 021L48R (left ventricle), 021V48R (superior vena cava), 021W48R (thoracic aorta, descending) and 021X48R (thoracic aorta, ascending/arch).
The same procedure with a different approach is coded 021708R (open).
With a different device, use 021749R (autologous venous tissue), 02174AR (autologous arterial tissue), 02174JR (synthetic substitute), 02174KR (nonautologous tissue substitute) and 02174ZR (no device).
It is an operating-room procedure in the MS-DRG logic for DRG 228 (Other Cardiothoracic Procedures with MCC) and DRG 229 (Other Cardiothoracic Procedures without MCC), under the surgical category “Other Cardiothoracic Procedures”.
It was added in FY2017, effective October 1, 2016.
