16.1 Health Underwriting and Risk Selection

Key Takeaways

  • Underwriting selects and classifies risk to prevent adverse selection while pricing each applicant fairly.
  • The four risk classes are Preferred, Standard, Substandard (rated), and Declined; substandard policies cost more, not less.
  • Adverse selection is the tendency of higher-risk applicants to seek coverage more aggressively than average risks.
  • Table ratings add roughly 25% to premium per table letter/number above standard; flat extras add fixed dollars per $1,000.
  • Group underwriting evaluates the whole group, not individuals, so most members qualify without evidence of insurability.

What Underwriting Does

Underwriting is the process of evaluating an applicant's risk, deciding whether to issue coverage, and setting the premium that matches that risk. The underwriter's job is risk selection and classification — grouping applicants so that each pays a premium proportional to the expected cost of insuring them. Done well, underwriting keeps the risk pool solvent and premiums fair.

The core threat underwriting defends against is adverse selection: the tendency of people who expect to file claims (those in poor health, hazardous jobs, or risky lifestyles) to seek insurance more aggressively than average risks. If insurers could not screen, the pool would fill with high-risk lives, claims would exceed premiums, and rates would spiral. Underwriting and proper risk classification are the controls that keep the pool balanced.

The Four Risk Classifications

Memorize these four classes and the direction each moves premium:

ClassificationMeaningPremium Effect
PreferredBetter-than-average health/lifestyleLowest premium
StandardAverage risk for age/sexBase (standard) premium
Substandard (rated)Higher-than-average riskHigher premium (rated up)
DeclinedUninsurable at any priceNo coverage offered

A frequent exam trap: substandard does not mean cheaper coverage. "Substandard" describes the risk, not the price — the policy is rated up, so the applicant pays more, never less.

Rating a Substandard Risk

Insurers price extra risk two ways. A table rating expresses risk as a series of tables (Table 1/A, 2/B, 3/C ...), each adding about 25% of the standard premium. A flat extra adds a fixed dollar amount per $1,000 of face for a specific or temporary hazard (e.g., a dangerous occupation or a recent surgery), and can be temporary or permanent.

Worked Example — Table Rating

Suppose a standard annual premium is $1,000 and the applicant is rated Table 4 (four tables above standard, 25% each = +100%):

  • Extra = 4 × 25% × $1,000 = $1,000
  • Rated premium = $1,000 + $1,000 = $2,000/year

Worked Example — Flat Extra

The same applicant has a $250,000 policy with a $5 per $1,000 flat extra for a 3-year aviation hazard:

  • Flat extra = ($250,000 ÷ 1,000) × $5 = 250 × $5 = $1,250/year for 3 years, then it drops off if temporary.

Underwriters may also issue an exclusion (impairment) rider that removes coverage for a specific condition rather than rating the whole policy, letting an otherwise standard applicant get coverage.

Individual vs. Group Underwriting

Individual underwriting evaluates one applicant in depth, often using the application, attending physician statements, and sometimes paramedical exams. Group underwriting is fundamentally different: the underwriter assesses the group as a whole — its size, industry, age distribution, and prior claims experience — not each member individually.

Because of this, most group members enroll without evidence of insurability during the initial enrollment, which is why group coverage is more accessible. Guardrails prevent adverse selection in groups:

  • The group must form for a purpose other than obtaining insurance (e.g., an employer or trade association).
  • A minimum participation percentage is required (commonly 75% for contributory plans, 100% for noncontributory employer-paid plans).
  • Late enrollees who skip the initial window typically must submit evidence of insurability.

Risk Factors Underwriters Weigh

  • Physical condition — height/weight, blood pressure, lab and exam results.
  • Medical history — personal and family history of disease.
  • Moral and morale hazard — dishonesty (moral) vs. carelessness/indifference (morale).
  • Avocation and occupation — hazardous hobbies and jobs add flat extras.
  • Tobacco/lifestyle — smoker rates can run 50–100% above nonsmoker rates.

Underwriting must comply with anti-discrimination rules: insurers may classify on legitimate actuarial factors but may not unfairly discriminate among applicants of the same class and risk.

Sources of Underwriting Information

The underwriter assembles a risk picture from several sources, each with a defined role on the exam:

  • The application — the primary source; everything begins here.
  • Attending Physician Statement (APS) — requested when the application reveals a condition the underwriter needs detailed records on; the applicant must sign an authorization.
  • Medical/paramedical exam — ordered above certain face amounts or ages; includes blood, urine, and vitals.
  • MIB report — coded impairment data shared among member insurers; a lead only, never proof.
  • Consumer and investigative reports — third-party data on credit, character, and lifestyle, governed by FCRA (covered in 16.2).

Underwriting Levels and Trade-offs

Insurers balance speed against accuracy. Simplified-issue uses a few yes/no health questions and no exam — fast but limited face amounts and higher built-in mortality assumptions. Guaranteed-issue asks no health questions at all (common in some group and final-expense products) and prices for the worst case. Fully underwritten policies require exams and records, take longer, but earn the lowest rates because risk is precisely measured. Expect a question contrasting these three on the speed-versus-price axis.

STOLI and Insurable Interest at Underwriting

Underwriters also confirm insurable interest exists at policy inception — the applicant must stand to suffer a genuine loss from the insured's death. This screens out stranger-originated life insurance (STOLI), where investors fund a policy on someone with whom they have no relationship, which is prohibited.
