Coronary Artery Bypass Graft Surgery with Endarterectomy
A patient underwent coronary artery bypass grafting to four vessels including internal mammary to the left anterior descending (LAD), a reverse saphenous vein graft placed to the obtuse marginal (OM), the posterolateral branch (PLB) and the posterior descending (PDA) arteries. An endarterectomy was performed to a segment of the PDA prior to performing the distal anastomosis. Is it appropriate to assign a separate code for the endarterectomy or is it inherent to the CABG surgery? ...

Article Overview
This premium article explains how a coronary artery bypass graft surgery case involving an endarterectomy is treated from a coding perspective. It is intended for coding professionals who need general guidance on whether the endarterectomy is part of the bypass procedure or a separately reportable service. The article discusses the clinical scenario, the procedural context, and the reporting principle that applies when the endarterectomy is performed in preparation for bypass surgery.
Why This Topic Matters
Cardiovascular surgery cases can involve more than one procedure, and coding accuracy depends on understanding which services are bundled into the primary operation versus separately reportable. This topic is relevant to coders, auditors, and revenue integrity staff working with operative reports.
What You Will Learn
- How a bypass surgery case with an endarterectomy is evaluated for reporting purposes.
- Which procedural context is discussed in relation to coronary artery bypass graft surgery.
- What general type of coding distinction the article addresses between primary surgery and additional procedures.
- How operative documentation affects whether an additional vascular procedure is considered separately reportable.
