Overview: Not all health insurance policies are created equal in scope — some aim to cover virtually every health need, while others address only specific events or conditions.

Comprehensive Health Insurance

Comprehensive health insurance — also known as major medical insurance — provides broad protection against a wide range of healthcare services and financial losses. ACA-compliant major medical plans are required to cover ten Essential Health Benefits, including:

Preventive and wellness services (often at zero cost-sharing)
Ambulatory (outpatient) care
Emergency services
Hospitalization (inpatient care)
Prescription drugs
Maternity and newborn care
Mental health and substance use disorder services
Rehabilitative and habilitative services
Laboratory services
Pediatric services (including dental and vision for children)

Comprehensive policies feature an out-of-pocket maximum — the most a member must pay in a plan year for covered services. Once that ceiling is reached, the insurer pays 100% of covered costs for the remainder of the year, protecting against catastrophic financial loss. They cannot impose annual or lifetime dollar limits on essential health benefits.

Limited Health Insurance Policies

A limited health insurance policy provides benefits for only specific, narrowly defined medical events or up to strict dollar caps. These plans are not ACA-compliant and are exempt from federal essential benefit requirements. They can deny coverage based on health history, exclude pre-existing conditions, and cap total benefits at low amounts.

The critical danger of limited policies is this: a $100,000 hospital bill is not a disaster for someone with comprehensive coverage (who pays only up to their out-of-pocket maximum), but it can be financially ruinous for someone with a limited policy that caps its payout at $5,000. Limited policies should never be treated as a substitute for major medical coverage — they function best as supplements to fill gaps.

Feature	Comprehensive (Major Medical)	Limited Benefit Plan
Pre-existing conditions	Must cover (ACA-compliant)	May exclude
Annual/lifetime limits	Prohibited on EHBs	Yes — strict caps
Out-of-pocket maximum	Required	Not required
Benefit payment	Pays providers directly	Often fixed cash to insured
ACA compliance	Yes	No
Primary purpose	Primary healthcare protection	Supplement; specific events only

Types of Limited Policies

The exam expects you to recognize three common limited policy types:

Hospital indemnity insurance pays a fixed cash benefit directly to the policyholder when hospitalized — not to the hospital based on the actual bill. A typical policy might pay $1,000 upon admission, plus $200 per day during confinement and $400 per day in the ICU. Because the cash goes directly to the insured, it can pay for anything: the deductible, lost wages, childcare, or household bills. Hospital indemnity plans have no networks — the insured receives care anywhere and still gets the fixed benefit. They are most valuable as supplements to high-deductible health plans (HDHPs), where a hospitalization could trigger a large deductible expense.

Dread disease insurance (also called critical illness insurance) pays a lump-sum cash benefit upon diagnosis of a covered serious illness. The "Big Three" covered conditions are cancer, heart attack, and stroke, though more comprehensive policies add kidney failure, major organ transplant, coronary artery bypass, paralysis, advanced neurological conditions (ALS, Parkinson's, Alzheimer's), and loss of sight, hearing, or speech. Policies typically require a survival period (commonly 14 days) between diagnosis and payout. The lump sum is unrestricted — the insured can use it for experimental treatments, travel to a specialist, home modifications, or simple living expenses during a lengthy recovery. Dread disease insurance is most appropriate for individuals with a strong family history of serious illness, those with high-deductible plans, primary breadwinners, or anyone with limited liquid savings to weather a multi-month medical crisis.

Accident-only insurance covers losses caused exclusively by sudden accidental injury. It pays nothing for sickness. Covered perils typically include fractures, dislocations, concussions, burns, lacerations, torn ligaments, accidental eye or dental injuries, and AD&D benefits for accidental death or dismemberment. It also covers related services: ambulance transport, ER visits, surgery, imaging, follow-up physician visits, and physical therapy. Accident-only insurance is appropriate as a supplement for people with active lifestyles or active children, gig workers and self-employed individuals without paid leave, employees in physically demanding jobs (for off-the-job protection that workers' compensation does not provide), and anyone who wants a low-cost financial buffer against the large deductibles common in modern HDHPs.
