About 02104K3

02104K3 is the ICD-10-PCS code for a bypass procedure on the coronary artery, one artery using a percutaneous endoscopic approach with nonautologous tissue substitute (qualifier: coronary 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 other bypass anastomosis for heart revascularization, the ICD-9-CM procedure title it maps to (36.19).

For a different body part, codes include 02114K3 (coronary artery, two arteries), 02124K3 (coronary artery, three arteries) and 02134K3 (coronary artery, four or more arteries).

The same procedure with a different approach is coded 02100K3 (open).

With a different device, use 0210483 (zooplastic tissue), 0210493 (autologous venous tissue), 02104A3 (autologous arterial tissue), 02104J3 (synthetic substitute) and 02104Z3 (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.
