Health Insurance Underwriting and Risk Selection
What the domain tests
How risk is classified, priced and controlled for individual, family and group health business, and which tools keep the risk pool solvent.
Core rules
- Rating factors: age, gender, sum insured, city zone, plan type, family size and the individual's health history - body mass index, blood pressure, diabetes, cardiac and renal history, tobacco and alcohol use, family history and occupation.
- Tools: the proposal form (the disclosure duty), tele- and video-medicals, pre-policy medical check-ups triggered by age or sum insured, and prior claim data from the Insurance Information Bureau repository and from insurer or TPA records.
- Outcomes: standard acceptance, acceptance with loading (extra premium for a defined period), acceptance with permanent exclusion of a declared condition, postponement, or decline.
- Waiting periods do what pricing cannot: an initial waiting period for illness (accident cover usually starts at once), a regulated waiting period for declared pre-existing diseases (commonly three years) and a shorter one for specified diseases such as hernia or cataract.
- Group business is rated at scheme level - occupation, age band, member count and past claims ratio - and individual medicals are normally waived.
- The disclosure duty is continuing. Non-disclosure of a known condition allows a claim to be rejected, but only within the moratorium window; regulation fixes when that protection attaches.
Worked example
An applicant aged 58, body mass index 33, with type 2 diabetes for six years, seeks ₹10,00,000 cover. The underwriter accepts with a 25% extra premium for a stated period, applies the standard three-year pre-existing disease waiting period, and keeps out complications attributable to uncontrolled diabetes during that period. Nothing is declined: the risk is priced and timed rather than refused.
Traps that cost marks
- Confusing a permanent exclusion (which survives the moratorium if listed in the policy) with an ordinary waiting period.
- Assuming a group scheme gives members individual risk classification.
- Forgetting that sum insured and zone, not only age, drive rating.
