About 0211499

0211499 is the ICD-10-PCS code for a bypass procedure on the coronary artery, two arteries using a percutaneous endoscopic approach with autologous venous tissue (qualifier: left internal mammary). 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 Double internal mammary-coronary artery bypass, the ICD-9-CM procedure title it maps to (36.16).

For a different body part, codes include 0210499 (coronary artery, one artery), 0212499 (coronary artery, three arteries) and 0213499 (coronary artery, four or more arteries).

The same procedure with a different approach is coded 0211099 (open).

With a different device, use 0211489 (zooplastic tissue), 02114A9 (autologous arterial tissue), 02114J9 (synthetic substitute), 02114K9 (nonautologous tissue substitute) and 02114Z9 (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.
