About 021L48R

021L48R is the ICD-10-PCS code for a bypass procedure on the left ventricle 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 heart revascularization by arterial implant, the ICD-9-CM procedure title it maps to (36.2).

For a different body part, codes include 021648R (right atrium), 021748R (left atrium), 021K48R (right ventricle), 021V48R (superior vena cava), 021W48R (thoracic aorta, descending) and 021X48R (thoracic aorta, ascending/arch).

The same procedure with a different approach is coded 021L08R (open).

With a different device, use 021L49R (autologous venous tissue), 021L4AR (autologous arterial tissue), 021L4JR (synthetic substitute), 021L4KR (nonautologous tissue substitute) and 021L4ZR (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.
