8.1 Underwriting Process, Risk Classification, and MIB
Key Takeaways
- Underwriting selects and classifies risk to prevent adverse selection while charging premiums that match each applicant's mortality risk.
- Standard risk classes run from Preferred Plus (lowest cost) through Standard to Substandard (rated) and Declined.
- Substandard risk is priced two ways: table rating (a percentage add-on, roughly 25% per table) and flat extras (fixed dollars per $1,000).
- The Medical Information Bureau (MIB) is a member-funded clearinghouse of coded medical impairments used to detect omissions and fraud, not to make underwriting decisions alone.
- Federal law (FCRA) requires Fair Credit Reporting Act disclosure and adverse-action notice when consumer or investigative reports affect the decision.
The Purpose of Underwriting
Underwriting is the process an insurer uses to evaluate the risk presented by an applicant, decide whether to issue coverage, and set the premium. The underwriter's core job is risk selection and classification: grouping applicants so each one pays a premium that fairly reflects the mortality or morbidity risk they bring to the pool.
The driving threat is adverse selection, the tendency of people who expect to file claims (the unhealthy, the high-risk) to buy more insurance than average. If an insurer ignores this, sick lives crowd the pool, claims exceed premiums, and the insurer becomes insolvent. Underwriting also blocks anti-selection by class and guards solvency so future claims can be paid.
The Risk-Classification Ladder
Underwriters sort applicants into standard classes that map directly to price. The ladder runs from the healthiest, cheapest tier to the uninsurable.
| Class | Profile | Premium effect |
|---|---|---|
| Preferred Plus / Super Preferred | Ideal build, no tobacco, clean family history | Lowest premium |
| Preferred | Very good health, minor issues allowed | Below average |
| Standard | Average mortality risk | Average (the baseline rate) |
| Substandard (Rated) | Above-average mortality risk | Higher, via rating |
| Declined | Risk too high to insure | No offer made |
Tobacco use creates parallel smoker classes; a smoker who is otherwise excellent qualifies only for Preferred Tobacco, not Preferred Plus. Smokers commonly pay two to three times the nonsmoker rate.
Factors evaluated
- Medical: current health, history, build (height/weight), blood pressure, cholesterol, lab tests (glucose, HIV, nicotine).
- Lifestyle: tobacco and alcohol use, recreational drugs, hazardous avocations (skydiving, scuba), foreign travel.
- Personal/demographic: age (the dominant factor), occupation, driving record, family history, and (where legally permitted) gender.
Pricing Substandard Risk: Worked Math
When an applicant exceeds standard mortality, the insurer keeps the risk but raises the price two ways.
Table rating
Each table (often Table A, B, C... or Table 1, 2, 3...) adds roughly 25% of the standard premium per step.
| Table | Add-on | Multiplier of standard |
|---|---|---|
| Table 1 (A) | +25% | 1.25x |
| Table 2 (B) | +50% | 1.50x |
| Table 4 (D) | +100% | 2.00x |
Worked example: standard annual premium is $800. The applicant is rated Table 4. The add-on is 4 x 25% = 100%, so the multiplier is 2.00. Premium = $800 x 2.00 = $1,600 per year.
Flat extra
A flat extra adds a fixed dollar amount per $1,000 of face, usually for a temporary or specific risk (a hazardous hobby, a recent surgery).
Worked example: a $250,000 policy carries a $2.50 flat extra per $1,000. Flat extra = (250,000 / 1,000) x $2.50 = $625 per year, added on top of the base premium. Flat extras may be temporary (drop off after 3-5 years) or permanent.
Underwriters may also impose an exclusion rider (no coverage for a named condition or activity) or a graded/modified benefit rather than full rating.
Sources of Underwriting Information and the MIB
Underwriters assemble a file from several sources:
- The application itself (the primary source) and the producer's statement/report.
- Attending Physician Statement (APS) ordered when the application flags a condition.
- Paramedical exams, blood, and urine for larger face amounts.
- Inspection / consumer reports on lifestyle and finances.
- The Medical Information Bureau (MIB).
The Medical Information Bureau (MIB) is a nonprofit clearinghouse owned by its member insurers. When a member underwrites an applicant, significant impairments are reported to MIB as brief codes (not full medical records). A later underwriter checks MIB to spot omissions and fraud, for example an applicant who failed to disclose a condition reported by a prior insurer.
Trap: An insurer may not decline or rate an applicant solely on an MIB code. The code is a flag that must be independently verified; the decision rests on the underwriter's own evidence.
An applicant's standard annual premium is $1,200. The underwriter assigns Table 4 (each table = 25% of standard). What is the annual premium?
Federal Consumer Protections (FCRA)
When an insurer orders an outside report, the federal Fair Credit Reporting Act (FCRA) applies. The applicant must receive notice that a consumer report (lifestyle, credit) or investigative consumer report (interviews with associates) may be obtained. If the insurer takes adverse action (decline, rate-up, or charge a higher premium) based on the report, it must give an adverse-action notice naming the reporting agency and the applicant's right to a free copy and to dispute errors.
The MIB itself is governed by FCRA: the applicant signs an MIB authorization on the application, can request their MIB record, and can correct inaccuracies. These rules ensure underwriting is fair, transparent, and based on verifiable facts rather than rumor.
An insurer declines an applicant after reviewing an MIB code indicating a prior cardiac impairment. Which statement is correct?
