B21F1ZZFluoroscopy of Other Bypass Graft using Low Osmolar Contrast

B21F1ZZ is the ICD-10-PCS code for a fluoroscopy procedure on the bypass graft, other using a low osmolar approach with none (qualifier: none). In ICD-10-PCS, fluoroscopy means single plane or bi-plane real time display of an image developed from the capture of external ionizing radiation on a fluorescent screen. The image may also be stored by either digital or analog means.

In plain terms, this corresponds to coronary arteriography using a single catheter and coronary arteriography using two catheters, the ICD-9-CM procedure titles it maps to (88.55 and 88.56).

For a different body part, codes include B2101ZZ (coronary artery, single), B2111ZZ (coronary arteries, multiple), B2121ZZ (coronary artery bypass graft, single), B2131ZZ (coronary artery bypass grafts, multiple), B2141ZZ (right heart), B2151ZZ (left heart) and 3 more.

The same procedure with a different approach is coded B21F0ZZ (high osmolar) and B21FYZZ (other contrast).

It is a non-O.R. procedure that is part of the MS-DRG logic for DRG 212 (Concomitant Aortic and Mitral Valve Procedures), DRG 216 (Cardiac Valve and Other Major Cardiothoracic Procedures with Cardiac Catheterization with MCC), DRG 217 (Cardiac Valve and Other Major Cardiothoracic Procedures with Cardiac Catheterization with CC), DRG 218 (Cardiac Valve and Other Major Cardiothoracic Procedures with Cardiac Catheterization without CC/MCC), DRG 233 (Coronary Bypass with Cardiac Catheterization or Open Ablation with MCC) and DRG 234 (Coronary Bypass with Cardiac Catheterization or Open Ablation without MCC), under the surgical categories “Concomitant Aortic and Mitral Valve Procedures”, “”, “Cardiac Defibrillator Implant with Cardiac Catheterization” and 1 more.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
