Term Insurance Medical Underwriting Process: A Complete Guide

You have compared plans, picked a sum assured, and paid the premiums, then the insurer calls asking about your father's blood pressure or books you a blood test. 

If that sounds confusing, you are not alone, and that is exactly why it helps to understand the term insurance medical underwriting process before you apply, not after your family needs the payout. 

In this article, we will walk you through how the process works step by step, what a tele-MER or video-MER interview involves, and how insurers use medical grids to decide your test list. We also discuss common medical tests for term insurance. 

What Is Medical Underwriting in Term Insurance?

Medical underwriting is the part of the term insurance underwriting process where the insurer reviews your medical profile. 

The underwriter reviews your age, medical history, family history, BMI, and habits like smoking or drinking, then compares them with actuarial data to estimate your mortality risk.

This sits alongside financial underwriting, which checks whether the sum assured you requested is reasonable for your income. 

Together, the two decide whether your term insurance plan gets issued as applied for, gets modified, or needs a closer look. Even a plan marketed as term insurance without medical tests still involves underwriting. There, you're assessed on your declared answers instead of a lab report. 

The overall underwriting process takes about 4 days to 2 weeks but it can take longer for complex cases, customer delays, and Non-Resident Indians (NRIs).

Note: Even when insurer-arranged physical tests aren't required, underwriting still happens based on your disclosures and any other checks the insurer requires. 

An extra test request does not automatically mean rejection. It usually just means the insurer wants a more complete picture of your health before deciding.

Tele-MER and Video-MER: What Happens in a Telemedical Interview

A tele-MER, or Medical Examination Report, is a telephonic health interview, while a video-MER is the same interview over video so the examiner can also verify your identity. Both replace, or come before, a physical medical exam for term insurance, and both are scheduled at your convenience rather than requiring a clinic visit.

During the call, a doctor or trained examiner asks about your medical history, current medication, family history of conditions like diabetes or heart disease, and habits such as smoking, alcohol, or your occupation. 

If your answers raise questions, your sum assured is high, or you are above a certain age or already have pre-existing conditions, the insurer may still ask for a physical medical for term insurance, meaning an in-person visit for tests that cannot be done remotely, like blood draws or an ECG.

Medical Grids: How Insurers Decide Which Tests You Need

Insurers use a medical grid, a chart that maps age bands and sum assured slabs against the required tests. This is why two people applying for very different covers, or at different ages, can be asked for completely different medical tests for term insurance.

• Younger applicants under 35 with modest cover often may go through with just a tele-MER or no test at all.
• Once you are 35 and above, or asking for a higher sum assured (often ₹1 to ₹2 crore and above), physical tests usually become mandatory.
• Certain profiles almost always trigger tests regardless of age or cover. These include high-risk occupations, family history of serious illness, riders like critical illness, and profiles like housewives, the self-employed, and NRIs (Non-Resident Indians).

Exact cut-offs and test lists differ across insurers, so two companies can assess the same profile differently. This is one reason working with an advisor, rather than a single insurer's website, helps you understand what to expect before you commit.

Common Medical Tests for Term Insurance: Blood Profile, ECG, TMT, and HbA1c

A term insurance medical test list can include the following once tests are triggered:

• Basic Checks: height, weight, BMI, and blood pressure.
• Blood Profile: complete blood count, fasting blood sugar, HbA1c, which reflects your average blood sugar, and a lipid profile.
• Organ Function: liver and kidney function tests.
• Urine Examination: screening for nicotine or cotinine if you have declared yourself a non-smoker.
• Infection Screening: HIV and hepatitis, especially for higher sums assured.
• Cardiac Tests: an ECG and a TMT, also called a treadmill or stress test, to see how your heart responds to exertion.
• Imaging: a chest X-ray, lung-function test, or echocardiogram, depending on age and history.

Most of these are ordinary medical test for term insurance requirements rather than red flags. A normal HbA1c is generally below 5.7%, and 5.7% to 6.4% usually reads as prediabetes rather than diabetes, though the underwriter makes the final call based on your full profile.

Financial Underwriting and Documents Required Alongside Your Medical Tests

Financial underwriting checks that your requested sum assured is proportionate to your income, partly to protect you from over-insuring where people buy far more cover than their income justifies.

Documents Required for Term Insurance Plan

• Identity Proof: PAN, Aadhaar, and passport, especially for NRIs.
• Salaried Applicants: Salary slips, Form 16, and bank statements.
• Self-Employed Applicants: The last two to three years of ITRs, CA-certified COI (Computation of Income), and audited financials or bank statements.
• NRIs: Passport with visa or residence permit, overseas address proof, and sometimes a FATCA declaration.

These are collected alongside your medical documents, and both sets are reviewed together before the underwriter decides.

Ditto’s Key Insight: A loaded premium is not a rejection, and it is not a punishment either. It is simply the insurer pricing the risk it is taking on. Before accepting a counteroffer, look at the whole picture: the revised premium, cover amount, policy term, and rider status, not just the loading percentage in isolation.

Disclosure Mistakes That Cause Term Insurance Claim Rejection Later

The biggest risk in the term insurance medical underwriting process is not a bad medical report but an incomplete one. Under Section 45 of the Insurance Act, 1938, insurers can question a death claim within the first three years of the policy for misstatement or suppression of facts. After three years, they must prove the non-disclosure was deliberate and fraudulent.

The mistakes that cause the most trouble at the claim stage are small and avoidable at underwriting. These include marking yourself a non-smoker when you smoke occasionally, leaving out an old diagnosis because it feels resolved, rounding up your income to justify a higher sum assured. 

Insurers may also use industry data during underwriting. The Insurance Information Bureau (IIB) describes QUEST as a real-time life-insurance underwriting and claims search tool that can show an applicant's insurance history, including past rejections. Additionally, PRISM is a separate IIB tool used for predictive life-risk scoring. 

None of these guarantee a rejected claim, but they all give the insurer a reason to investigate one, at the exact moment your family can least afford the delay.

Conclusion

The term insurance medical underwriting process can feel intrusive while you are going through it. A phone call here, a blood test there, but it protects the payout your family eventually relies on. The real risk is not the tele-MER interview or the TMT test. It is treating disclosure as optional.

Our Advice: Answer the proposal form as accurately as you can, keep your medical and income documents ready before you apply, avoid applying to several insurers in parallel, and treat a fair loading as the cost of getting covered rather than a reason to hide anything. If you are unsure how your profile will be assessed, talk to an advisor before you apply.
