What Can Cause You to Fail a Life Insurance Medical Exam?

It is important to understand that you do not technically "fail" a life insurance medical exam — the exam results simply determine your risk classification, which affects your premium. However, certain findings can result in a higher-than-expected classification, a rated (more expensive) policy, or in some cases, a decline from the carrier. Knowing what the exam screens for and how results are interpreted helps you approach the process with realistic expectations.

The most impactful findings include elevated blood pressure (especially if uncontrolled or requiring multiple medications), abnormal blood sugar levels indicating diabetes or pre-diabetes, significantly elevated cholesterol (particularly when combined with other risk factors), protein or glucose in the urine sample, and liver enzyme elevations that may indicate alcohol use or liver disease. Each of these findings has different implications depending on severity, whether the condition is known and treated, and how the applicant disclosed it on the application. A known, well-managed condition is viewed far more favorably than one discovered during the exam that was not disclosed.

Tobacco or nicotine use detected in blood or urine testing will move you from non-smoker rates to smoker rates, which can double or triple your premium. This includes cigarettes, cigars, chewing tobacco, vaping, and even nicotine patches or gum in some carriers' underwriting guidelines. The financial impact of tobacco use is one of the most significant factors in life insurance pricing, and misrepresenting tobacco use on the application creates serious problems if detected — not just higher premiums but potential claim denial during the contestability period.

Other factors that affect results include high BMI (obesity), evidence of drug use including marijuana in some cases, and markers for serious conditions like HIV or hepatitis. Medical records that reveal undisclosed conditions, surgeries, or hospitalizations can also negatively impact your application, as they raise questions about the accuracy of your original application. The discrepancy between what you disclosed and what the records show is often more concerning to underwriters than the condition itself.

Certain medications detected through prescription database checks can also raise underwriting concerns even before the exam. Insulin for diabetes, anticoagulants for blood clotting disorders, multiple psychiatric medications, and opioid pain medications all trigger additional scrutiny. However, these medications also demonstrate that you are receiving treatment and managing your health — which is viewed more positively than an untreated condition.

Temporary factors can also skew exam results. A recent illness, strenuous exercise the day before, alcohol consumption within 24 hours, dehydration, lack of sleep, and high-sodium meals can all temporarily elevate readings. This is why preparation matters — scheduling the exam when you are well-rested, hydrated, and following your normal routine helps ensure results accurately reflect your baseline health rather than temporary fluctuations.

If you receive an unfavorable result, you have options. You can accept the offered classification and premium, appeal with additional medical documentation, request retesting if you believe results were affected by temporary factors, or apply to a different carrier with more favorable underwriting for your specific condition. Some carriers specialize in certain health conditions and may offer better rates. An agent in our network can help identify the best carrier for your health profile and navigate the appeals or reapplication process.

It is also worth noting that some carriers offer no-exam or accelerated underwriting pathways that bypass the medical exam entirely for qualifying applicants. These programs use electronic health data, prescription databases, and predictive algorithms to assess risk. If you have concerns about exam results, exploring these alternative pathways with an agent may be worthwhile, though they typically have age and coverage amount limitations.
