9.1 Health Insurance Concepts and Defining the Insured

Why Health Insurance Exists

Health insurance transfers the financial risk of medical care from an individual to an insurer in exchange for a premium. Two perils drive the need: medical expenses (the cost of treating illness or injury) and loss of income (the inability to earn while disabled). This unit focuses on the medical-expense side; disability income is covered separately.

Morbidity, not mortality, is the central risk in health insurance. Morbidity is the incidence and severity of sickness and accidents in a defined group. Actuaries price health products using morbidity tables the same way life insurers use mortality tables. Because morbidity rises with age and varies by occupation, both factors are core rating variables.

Insurable Interest and the Insured

In health insurance, insurable interest must exist at the time of application (unlike property insurance, where it must exist at the time of loss). A person always has an insurable interest in their own life and health, and a clear interest in a spouse and dependent children. An employer has a limited insurable interest in key employees.

Health coverage exists because medical and disability losses are unpredictable for the individual but predictable for the group. A single person cannot know whether they will face a $100,000 hospital stay next year, but an insurer covering 100,000 people can estimate aggregate claims closely. The insured trades a small certain cost (premium) for protection against a large uncertain one — the core principle of risk pooling.

Who Is the "Insured"?

The applicant is the person applying; the insured (or principal insured) is the person whose health is covered. On individual policies these are usually the same person. A dependent is a covered spouse or child added under family coverage. The policyowner holds the contract rights (renewal, beneficiary changes for any death benefit, conversion). On group plans, the employer is the policyowner and the employee is the certificate holder.

Key defining terms tested heavily on the exam:

A child generally remains an eligible dependent to age 26 under federal law, regardless of student or marital status.

Perils, Hazards, and Risk

A peril is the cause of loss (a heart attack, a car crash). A hazard increases the chance or severity of a loss. Three hazard types appear on the exam:

• Physical hazard — a bodily or material condition (a prior knee injury, a hazardous occupation).
• Moral hazard — dishonest tendencies, e.g., faking a claim or buying coverage intending to defraud.
• Morale hazard — indifference or carelessness because insurance exists ("the policy will pay, so why be careful?").

Insurers manage adverse selection — the tendency of higher-risk individuals to seek coverage more aggressively — through underwriting, pre-existing-condition rules, probationary periods, and pricing. The law of large numbers lets insurers predict aggregate losses accurately as the insured pool grows, which is why group coverage is cheaper per person than individual coverage.

Eligibility and Probationary Provisions

Many health policies impose a probationary period — a stated number of days after the effective date during which sickness (but typically not accidents) is not covered. This is distinct from the elimination period in disability income, which is a time-based deductible measured in days before benefits begin.

Worked example (eligibility math): A group plan requires 30 hours/week minimum and a 60-day waiting period. An employee hired June 1 working 35 hrs/week becomes eligible August 1 (60 days later). A part-timer at 25 hrs/week never satisfies the hours test and is ineligible regardless of tenure.

The stated benefit period is the window during which expenses for a single illness or injury are payable; benefit triggers are the events (diagnosis, hospital admission, disability) that start payments.

Renewability Provisions

How long an insurer must keep an individual policy in force is governed by its renewability clause, a frequently tested concept:

• Noncancelable — the insurer cannot cancel, cannot raise the premium, and must renew to a stated age. Strongest guarantee for the insured.
• Guaranteed renewable — the insurer must renew to a stated age but may raise premiums by class (never for one individual).
• Conditionally renewable — renewal is allowed only if stated conditions are met (e.g., still employed).
• Optionally renewable — the insurer may decline renewal on a policy anniversary or premium due date.
• Cancelable — the insurer may terminate at any time with notice (now restricted by law for many coverages).

Memory hook: 'Noncan' locks both renewal and rate; 'guaranteed renewable' locks only renewal.

Finally, distinguish the producer-of-record and the parties to the claim. When a covered loss occurs, the insured (or assignee, such as a hospital) submits proof of loss; the insurer adjudicates against the policy's definitions of insured, dependent, covered service, and benefit period. Misnaming any of these parties on an application can void coverage at claim time, so accurate completion of the application — listing every dependent and disclosing every material health fact — is the producer's core duty in this section.
