Medical Underwriting

Medical Underwriting is the assessment of an applicant's health risk by an insurer based on medical evidence — proposal form declarations, tele-underwriting calls, in-person medical examinations, laboratory test reports, and historical medical records. It is the substantive underwriting step that determines whether to accept a life or health insurance applicant, at what premium, with what exclusions, or whether to decline. The depth of medical underwriting varies with sum assured and age.

For small sum assureds at young ages (say, a ₹25 lakh term plan at age 28), medical underwriting may be limited to the proposal form declarations and a brief tele-call. For larger sum assureds at older ages (a ₹2 crore term plan at age 48), medical underwriting typically includes a full physical examination at a panel diagnostic centre, an ECG, a chest X-ray, blood tests covering complete blood count, lipid profile, fasting blood glucose, HbA1c (for diabetes detection), liver function, kidney function, and HIV serology, urine analysis, and sometimes a treadmill stress test (TMT) or echocardiography for cardiac risk assessment. The medical reports are reviewed by the insurer's medical underwriter, who applies a 'rating' relative to standard mortality — accepting at standard rates, applying a 'loading' as a percentage uplift to premium for adverse findings, attaching a permanent or time-limited exclusion for a specific condition, or declining cover.

Worked example: Arjun, 46, applies for a ₹3 crore term plan. Medical underwriting includes the full panel above. The reports show fasting glucose of 130 mg/dL (pre-diabetic range), HbA1c of 6.

3%, BMI of 28, and a borderline hypertension reading of 142/92 on the day of test. The underwriter applies a 35% loading on the standard premium of around ₹65,000, taking it to ₹87,750, and accepts the policy with no exclusion. Had the HbA1c been above 6.

5% with no clinical follow-up, the underwriter might have asked for additional records and applied a higher loading or declined cover. A common misconception is that medical underwriting is a one-time event at policy inception. For long-term contracts it largely is, but the contractual relevance of the underwriting medical extends through Section 45's three-year window for life insurance and through claim-stage scrutiny for health insurance.

Material findings or omissions at the original medical can be revisited if a claim arises within these windows. Another common misconception is that the medical test result belongs to the insurer alone. The proposer is entitled to a copy of all medical reports and any underwriter's reasoning, and the IRDAI has clarified this disclosure obligation.

If the policy is declined or loaded, ask for the underlying reports — the same evidence may be useful for a fresh proposal with a different insurer. Related: tele-underwriting, financial-underwriting, premium-loading.
