12.1 Health Insurance Concepts, Perils, and Cost-Containment
Key Takeaways
- Health insurance pools risk so premiums from many cover the medical and income losses of the few.
- Morbidity (sickness/disability frequency) drives health premiums, just as mortality drives life premiums.
- Hazards increase the chance of loss and come in three types: physical, moral, and morale.
- Adverse selection is the tendency of higher-risk persons to seek coverage; underwriting and waiting periods control it.
- Cost-containment tools include utilization review, pre-certification, gatekeepers, case management, and preventive care.
Health insurance transfers the financial risk of medical expenses and lost income from an individual to an insurer through the pooling of risk — many insureds pay premiums so the few who suffer losses can be paid. The national portion of the Life & Health exam tests these concepts uniformly across states; specific mandates and timelines live in your state-law chapters.
Two broad perils create the need for health coverage:
- Morbidity — the likelihood of sickness or disability within a population. Morbidity tables drive health premiums the way mortality tables drive life premiums.
- Mortality — the likelihood of death; relevant to health products only where a death benefit or accidental death rider exists.
Core Definitions
Memorize these distinctions; exams reword them constantly.
| Term | Meaning |
|---|---|
| Peril | The cause of a loss (illness, accident, injury). |
| Hazard | A condition that increases the chance of loss. |
| Morbidity | Frequency and severity of sickness/disability in a group. |
| Adverse selection | The tendency of higher-risk persons to seek or keep coverage more than lower-risk persons. |
| Indemnity | Restoring an insured to the financial position held before a loss — no profit. |
Three hazard types appear on the test:
- Physical hazard — a bodily or property condition (a chronic illness, a smoking habit).
- Moral hazard — dishonest tendencies (faking a claim, intentional injury).
- Morale hazard — indifference to loss because insurance exists (carelessness).
Why Adverse Selection Matters
Insurers fight adverse selection so the risk pool stays balanced. Tools include medical underwriting, pre-existing condition rules (now limited by the Affordable Care Act for most major medical), waiting/probationary periods, and minimum participation requirements on group plans.
Trap: Group insurance reduces adverse selection because employees join for employment, not because they are already sick — so individual underwriting is usually waived and a single rate applies to the group.
Cost-Containment Mechanisms
Managed-care plans use cost-containment to lower utilization and unit price. Know each one:
| Mechanism | What It Does |
|---|---|
| Utilization review | Evaluates whether care is medically necessary (concurrent, prospective, retrospective). |
| Prospective review / pre-certification | Approves a hospital stay or procedure before it occurs. |
| Concurrent review | Monitors care during a hospital stay. |
| Gatekeeper (Primary Care Physician) | Coordinates care and authorizes specialist referrals. |
| Second surgical opinion | Confirms the need for elective surgery. |
| Case management | Coordinates complex, high-cost care to reduce waste. |
| Preventive care | Free screenings/immunizations to catch illness early and cut later cost. |
Sources of Health Coverage
The national exam expects you to identify where coverage originates:
- Private commercial insurers — stock and mutual companies selling individual and group medical, dental, and disability plans.
- Service organizations — historically Blue Cross (hospital) and Blue Shield (physician) plans that contract directly with providers.
- Health Maintenance Organizations — prepaid managed-care entities delivering and financing care.
- Government programs — Medicare (age 65+ and certain disabled), Medicaid (means-tested), and the Children's Health Insurance Program (CHIP).
- Self-funded employer plans — the employer bears claims risk directly, often using stop-loss reinsurance and a third-party administrator.
How Premiums Are Built
A health premium reflects expected morbidity, administrative loading, and a margin. Three rating methods appear on the exam:
- Community rating — every insured in an area pays the same rate regardless of health; common under the Affordable Care Act for individual major medical.
- Experience rating — a group's own past claims determine its rate; rewards healthy groups with lower premiums.
- Manual (class) rating — rates come from standard tables by age, gender (where allowed), and risk class.
Trap: Community rating spreads cost across all insureds and limits how much premiums can vary by health, while experience rating ties a specific group's premium to that group's claims history.
An insurer requires hospital admissions to be approved before the patient is admitted. Which cost-containment mechanism is this?
A person who buys health coverage only after being diagnosed with a serious illness is an example of what problem insurers guard against?
Morbidity vs. Mortality
Health insurance is priced on morbidity — the incidence of sickness and disability in a population — whereas life insurance uses mortality (death rates). Morbidity tables predict how often and how long insureds will be sick or disabled, driving health and disability premiums. Because people get sick far more often than they die, health claims frequency is higher and pricing is more sensitive to utilization, which is why cost-containment features matter so much.
Managed Care Cost-Containment Tools
Health plans control cost through specific mechanisms the exam lists: preauthorization/precertification (approval before nonemergency hospitalization), utilization review (concurrent and retrospective review of necessity), gatekeeper PCP referrals, second surgical opinions, case management for catastrophic claims, and wellness/preventive incentives. Cost-sharing (deductibles, copays, coinsurance) shifts some cost to the insured to discourage overuse. Distinguish prospective (before), concurrent (during), and retrospective (after) review.
Health insurance premiums are based primarily on:
Perils Covered: Accident vs. Sickness
Health (accident-and-sickness) insurance covers two perils. Accident is a sudden, unforeseen, external event; older policies used the strict accidental means standard (both the cause and result must be unexpected), while modern policies use the more liberal accidental bodily injury (results) standard. Sickness is an illness or disease that first manifests while the policy is in force, often after any probationary period. Distinguishing accidental means from accidental results, and accident from sickness, determines which benefits and waiting periods apply.
Categories of Health Coverage
The exam groups health products into broad categories: medical expense (HMO/PPO/major medical reimbursing care), disability income (replacing lost wages), long-term care (custodial and skilled care), and supplemental/limited (Medigap, dental, vision, critical illness, hospital indemnity). Each category uses different pricing (morbidity), benefit triggers, and tax rules. Knowing where a described product fits in this taxonomy helps eliminate wrong answers quickly on scenario questions.
