8.1 Underwriting Process, Risk Classification, and MIB

Key Takeaways

  • Underwriting selects and classifies risks to set adequate premiums and prevent adverse selection; the home-office underwriter makes the final decision while the producer is the field underwriter.
  • Risk classes run Preferred (lowest premium) to Standard to Substandard (rated) to Declined; preferred is better than standard, substandard is worse but still insurable.
  • Substandard risks are rated by table (about +25% per table) or by a flat extra dollar amount per $1,000 for temporary hazards.
  • Underwriting sources include the application (primary), agent's report, medical exams, the Attending Physician Statement (APS), and FCRA-regulated inspection reports.
  • The Medical Information Bureau (MIB) stores only coded impairments and may not be the sole basis for declining an application.

What Underwriting Is

Underwriting is the process an insurer uses to evaluate an applicant's risk, decide whether to issue coverage, and set the premium that matches that risk. On the national licensing exam, underwriting questions test whether you can identify who classifies risk, what information is used, and how classifications change the premium.

The central goal is to select and classify risks so that each policyholder pays a premium proportional to the loss they bring to the pool. Done well, underwriting blocks adverse selection (the tendency of higher-risk people to seek more coverage) while keeping the insurer solvent enough to pay claims.

Underwriting Objectives

ObjectiveWhat it accomplishes
Risk selectionDecide whether the applicant is acceptable at all
Risk classificationPlace the applicant in the correct rate category
Premium adequacyCharge a premium that reflects expected mortality
EquityEnsure similar risks pay similar premiums
Anti-selection controlKeep disproportionately high risks from buying at standard rates

Exam tip: The home-office underwriter makes the final risk decision. The producer (agent) is the field underwriter who gathers facts and screens obvious risks but does NOT approve the policy.

Risk Classifications

Applicants are sorted into classes by mortality risk relative to the general population. Memorize the order from best to worst.

ClassDescriptionPremium
Preferred / Preferred PlusExcellent health, ideal build, no tobaccoLowest
StandardAverage health and mortalityAverage
Substandard (rated)Above-average mortality riskHigher (rated up)
DeclinedRisk too high to insureNo coverage

A preferred applicant is better than standard; a substandard applicant is worse than standard. Both are insurable. Only the declined class receives no offer.

Rating Substandard Risks

Insurers charge extra for substandard applicants two ways:

  • Table rating (percentage method): each table adds about 25% of the standard premium. Table 1 (A) = +25%, Table 2 (B) = +50%, Table 4 (D) = +100%. So a Table 2 risk pays 150% of the standard premium.
  • Flat extra premium: a fixed dollar amount per $1,000 of coverage (for a temporary or specific hazard such as a dangerous hobby). A flat extra of $5 per $1,000 on a $100,000 policy adds $500 per year and can be removed when the hazard ends.

Worked example: Standard annual premium is $1,200. A Table 3 (C) rating adds 75%, so the rated premium is $1,200 x 1.75 = $2,100.

Factors and Information Sources

Underwriters weigh age (the single biggest mortality factor), health history, build (height/weight), tobacco and alcohol use, occupation, hazardous hobbies, driving record, and family medical history.

They gather facts from several sources:

  • The application is the primary source. Part 1 is general data (name, age, occupation, income); Part 2 covers medical history. The producer's agent's report adds personal observations.
  • Medical exams (paramedical or full) supply blood/urine results for larger or older-applicant cases.
  • Attending Physician Statement (APS) is the applicant's own doctor's record, requested when the application reveals a condition. It can take weeks to obtain.
  • Inspection report (e.g., from a consumer-reporting agency) verifies lifestyle and finances; regulated by the Fair Credit Reporting Act (FCRA).

The Medical Information Bureau (MIB)

The Medical Information Bureau (MIB) is a nonprofit, member-owned database that stores coded medical and certain non-medical impairments reported by member insurers. Its purpose is to detect omissions or misrepresentation on applications.

MIB factDetail
StoresCoded conditions, NOT full medical records
Does NOT storeDiagnoses in plain English, claim history, underwriting decisions
Use limitAn MIB code alone may not be the sole basis to decline
Consumer rightsOne free disclosure on request; right to dispute and correct

Trap: MIB information cannot be used by itself to deny coverage. The insurer must verify the impairment through its own underwriting before acting on a code.

Federal Rules That Shape Underwriting

Several federal laws constrain how underwriters collect and use information. The exam tests the trigger and the consumer protection of each.

LawWhat it governsKey duty
Fair Credit Reporting Act (FCRA)Use of consumer/investigative reportsApplicant must be told a report may be ordered; on adverse action the insurer names the reporting agency
USA PATRIOT Act / anti-money-laundering (AML)Source of premium fundsInsurers verify identity and report suspicious activity on cash-value products
HIPAA privacyProtected health informationLimits sharing of medical data; applicant signs an authorization to release records
Genetic Information Nondiscrimination Act (GINA)Genetic test resultsRestricts certain uses in health underwriting

Adverse Selection vs. Anti-Selection in Practice

Underwriting exists because applicants know more about their own health than the insurer does - an information asymmetry. Adverse selection is the result: people most likely to claim are most eager to buy. Tools that counter it include medical exams, the MIB, waiting periods, suicide clauses, and accurate risk classification. When an underwriter cannot classify confidently, the application is postponed (decision deferred) rather than declined - a distinction the exam draws between declined (never insurable now) and postponed (revisit later).

Trap: A rated (substandard) policy still issues and pays full death benefits; the higher mortality risk is reflected in the premium, not in a reduced benefit.
