16.1 Health Underwriting and Risk Selection

Health Underwriting and Risk Selection

Underwriting is the process of selecting, classifying, and pricing risks so that the premiums collected from a class of insureds are adequate to pay that class's expected claims plus expenses and a margin. The underwriter is the financial gatekeeper: the producer brings applicants in (field underwriting), but the home-office underwriter decides whether to accept, rate, modify, or decline the risk.

The goal is fair discrimination — grouping applicants with similar expected loss together so each pays a rate appropriate to their risk. This is legal and necessary. Unfair discrimination — charging different rates to people of the same actuarial class, or refusing coverage for a reason unrelated to risk — is prohibited by every state's unfair trade practices act.

The Law of Large Numbers and Risk Classes

Insurers rely on the law of large numbers: the larger the pool of similar exposure units, the more closely actual losses approach predicted losses. Underwriting protects the pool from adverse selection — the tendency of higher-risk applicants to seek and keep coverage more aggressively than healthy people.

Health and disability underwriters sort applicants into rate classes. Unlike life insurance, health pricing also weighs morbidity (likelihood of sickness or disability) rather than mortality alone. A risk that is uninsurable for life coverage may still be writable for health coverage, and vice versa, so the two lines apply different standards to the same person.

Insurable Interest and Acceptable Risk

A valid policy requires insurable interest — the applicant must face a genuine financial or emotional loss if the insured event occurs. In life insurance, insurable interest need only exist at the time of application (not at death); a creditor, business partner, or family member ordinarily qualifies. Stranger-originated life insurance (STOLI), where investors buy a policy on a person they have no interest in, is illegal because it lacks insurable interest.

An ideal insurable risk is one of a large number of homogeneous units, with losses that are definite, measurable, accidental, not catastrophic, and economically feasible to insure. Underwriting screens applicants against these characteristics to keep the product priceable.

Underwriting Decisions

After reviewing the file, the underwriter reaches one of several outcomes:

A rated (substandard) policy is still issued — it simply costs more. Methods include a flat extra premium (a fixed dollar add-on per $1,000 of coverage, used for a temporary hazard like a recent surgery) and a table rating (a percentage surcharge, e.g., Table 4 = standard + 100%).

Worked Example: Table Rating and Flat Extra

An applicant qualifies at Table 2, defined as standard plus 50%. If the standard annual premium for the face amount is $800, the rated premium is $800 + (0.50 x $800) = $1,200.

Now suppose the applicant is also a private pilot, adding a temporary flat extra of $2.50 per $1,000 on a $200,000 policy: 200 units x $2.50 = $500 per year. Total annual premium = $1,200 + $500 = $1,700. The flat extra can be dropped later if the hazard ends; the table rating reflects a permanent health impairment and typically stays.

Justifying the Amount: Human Life Value and Needs Analysis

Underwriters also confirm the requested face amount is reasonable for the applicant's finances — a check against over-insurance and adverse selection. Two methods estimate appropriate coverage:

• Human Life Value (HLV) — the present value of the insured's future earnings devoted to dependents. Example: $80,000 income, with $30,000 consumed by the insured, leaves $50,000/year for the family. Over 20 remaining work years (simplified, undiscounted) that is $50,000 x 20 = $1,000,000 of economic value to replace.
• Needs analysis — adds up specific obligations (final expenses, mortgage, education, income replacement) minus existing assets. If needs total $700,000 and the family already holds $250,000 in savings and group life, the gap is $450,000 of new coverage.

Factors and Hazards

Key health-underwriting factors include age, gender, build (height/weight), tobacco use, medical history, family history, occupation, avocations (hobbies), and foreign travel. The underwriter evaluates two kinds of hazard:

• Physical hazard — a condition of the body or environment increasing the chance of loss (e.g., diabetes, hazardous occupation).
• Moral hazard — dishonesty or a tendency toward loss because of who the person is (e.g., a history of insurance fraud).
• Morale hazard — indifference or carelessness because insurance exists (an attitude, not outright dishonesty).

Trap: moral hazard = dishonest character; morale hazard = careless attitude. Exam writers swap these constantly.

Sources and the Limits of Selection

Underwriters pull from the application, the medical exam or paramedical report, the Attending Physician's Statement (APS), the Medical Information Bureau, prescription and motor-vehicle databases, and credit-based inquiries. They weigh these together rather than declining on a single flag.

Underwriting must respect anti-discrimination limits. An insurer may not refuse coverage or charge more based on race, national origin, or other protected characteristics unrelated to actuarial risk, and many states restrict the use of genetic information or domestic-violence status. The principle is consistent: classify by demonstrated risk, never by prejudice. Properly done, selection lets the insurer offer the lowest sustainable premium to each fairly defined class.
