About 021148W

021148W is the ICD-10-PCS code for a bypass procedure on the coronary artery, two arteries using a percutaneous endoscopic approach with zooplastic tissue (qualifier: aorta). 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 (Aorto)coronary bypass of two coronary arteries, the ICD-9-CM procedure title it maps to (36.12).

For a different body part, codes include 021048W (coronary artery, one artery), 021248W (coronary artery, three arteries) and 021348W (coronary artery, four or more arteries).

The same procedure with a different approach is coded 021108W (open).

With a different device, use 021149W (autologous venous tissue), 02114AW (autologous arterial tissue), 02114JW (synthetic substitute) and 02114KW (nonautologous tissue substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 231 (Coronary Bypass with PTCA with MCC), DRG 232 (Coronary Bypass with PTCA without MCC), DRG 233 (Coronary Bypass with Cardiac Catheterization or Open Ablation with MCC), DRG 234 (Coronary Bypass with Cardiac Catheterization or Open Ablation without MCC), DRG 235 (Coronary Bypass without Cardiac Catheterization with MCC) and DRG 236 (Coronary Bypass without Cardiac Catheterization without MCC), under the surgical categories “” and “Coronary Bypass without Cardiac Catheterization”.

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