Chapter 4 — Disability Income Underwriting

An applicant’s occupation is the most important single factor in disability income underwriting. Occupations are classified according to the disability hazards they represent. Although classification systems vary among insurers, occupations are generally divided into five or six classes, differing primarily in the extent of manual work involved.

The highest occupation classes (e.g., Class 5 or 6) include professional and executive occupations with little or no manual work — physicians, attorneys, accountants, executives. The lowest classes include heavy manual labor occupations with the highest disability exposure.

An applicant’s occupation class affects:

• The amount of coverage available — higher risk classes are limited to lower benefit amounts.
• The quality of provisions — noncancellable and guaranteed renewable coverage, own occupation definitions, and most riders are generally available only to the higher occupation classes.
• The premium charged — higher risk classes pay higher premiums for identical benefit amounts.

Financial underwriting for disability insurance is primarily concerned with overinsurance — ensuring the insured has sufficient financial motivation to seek to return to work after becoming disabled. If disability income benefits replace 100% or more of pre-disability income, the insured has little incentive to recover and return to work.

As a result, the maximum disability income benefit an insurer will issue is typically 60%–70% of gross income. This level provides meaningful income replacement while preserving the financial incentive to return to work.

When multiple disability income policies exist, each insurer considers the totality of coverage. Group disability benefits may interact with individual coverage when calculating the maximum insurable amount.

Medical underwriting focuses on the proposed insured’s health history and whether that history increases the likelihood of disability claims (morbidity). The underwriter reviews:

• Current health conditions and medications
• Past hospitalizations, surgeries, and treatments
• Chronic or recurring conditions
• Family health history
• Lifestyle factors (smoking, alcohol, avocations)

When the medical history presents increased risk, the underwriter has three tools for managing the impaired risk:

• Rejection — declining coverage entirely for uninsurable applicants.
• Increased premium — charging a higher premium (rating) to reflect the increased risk while offering standard provisions.
• Exclusion rider — excluding specific conditions or body parts from coverage while offering standard premiums and provisions for all other causes of disability. For example, an applicant with a history of lower back problems may receive a policy that excludes disabilities caused by lower back conditions.

The split elimination period discussed in Chapter 2 is another underwriting tool — offering a longer elimination period for a specific condition while providing a standard elimination period for all other causes.

Disability income underwriting centers on three concerns: occupational hazard, financial motivation to return to work, and health history. Occupation classification is the most fundamental factor, determining not just the premium but the very types and quality of provisions available. Financial underwriting protects against overinsurance, and medical underwriting adjusts terms for applicants with health histories that increase morbidity risk.
