About 02104AF

02104AF is the ICD-10-PCS code for a bypass procedure on the coronary artery, one artery using a percutaneous endoscopic approach with autologous arterial tissue (qualifier: abdominal 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 Abdominal-coronary artery bypass, the ICD-9-CM procedure title it maps to (36.17).

For a different body part, codes include 02114AF (coronary artery, two arteries), 02124AF (coronary artery, three arteries) and 02134AF (coronary artery, four or more arteries).

The same procedure with a different approach is coded 02100AF (open).

With a different device, use 021048F (zooplastic tissue), 021049F (autologous venous tissue), 02104JF (synthetic substitute), 02104KF (nonautologous tissue substitute) and 02104ZF (no device).

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