Risk Classes and Underwriting Decisions

The Underwriting Process and Mortality Risk

Underwriting is the process of evaluating an applicant to determine insurability and assign the proper risk classification. For individually underwritten life insurance, the insurer evaluates the applicant's expected mortality risk; guaranteed issue coverage generally does not assess an applicant's individual medical risk. Mortality rate refers to the expected frequency of death within a specific population group over a given period. Insurers use mortality tables and, when individual underwriting applies, applicant information to estimate expected mortality risk.

Risk classification helps insurers charge premiums that fairly reflect the expected mortality risk of each group of applicants. If an insurer charged everyone the exact same premium regardless of health or lifestyle, lower-risk individuals would end up overpaying while higher-risk individuals would be undercharged. By grouping individuals with similar risk profiles together, insurers ensure fair pricing across their entire book of business.

To evaluate health, underwriters look closely at the applicant's current physical condition, medical history, and hereditary factors. They examine measurements such as height and weight, including body mass index. Tobacco use generally prevents an applicant from qualifying for nonsmoker rates and may increase premiums. Family medical history gives underwriters insight into potential genetic predispositions to conditions such as cancer or heart disease. When more medical information is needed, an underwriter may request an attending physician's statement from the applicant's doctor; with the applicant's authorization, the insurer may also consult coded underwriting information shared through MIB, Inc.
