Bypass surgery test generally refers to the diagnostic evaluations, such as coronary angiography and stress testing, used to determine whether a patient needs coronary artery bypass graft (CABG) surgery. In underwriting language, it often appears in medical records describing pre-surgical workups for severe coronary artery disease. These tests assess the extent and location of blockages, heart function, and the viability of revascularization strategies. A history of bypass-related testing, especially when followed by CABG, signals significant cardiovascular disease and materially increases mortality risk. Underwriters pay close attention to test results, surgical outcomes, and postoperative follow-up when evaluating such cases.

Underwriters review bypass surgery test records, including catheterization reports, ejection fraction measurements, and stress-test results, to gauge the severity of coronary disease before and after surgery. They look for successful revascularization, absence of major complications, and evidence of lifestyle change or ongoing cardiology follow-up. Advisors working with clients who have undergone bypass-related testing gather comprehensive cardiology records and set expectations for table ratings or possible postponements. In some cases, simplified or guaranteed-issue coverage may be more realistic than fully underwritten policies. Understanding bypass surgery tests helps advisors discuss heart-disease underwriting candidly while advocating for the best attainable offers.
