9.2 Medical Expense Insurance (Basic and Major Medical)

The Two Historical Layers of Medical Expense Coverage

Medical expense insurance reimburses the cost of treating illness and injury. The exam still tests the two legacy structures that modern plans evolved from: basic medical expense and major medical.

Basic medical expense policies are first-dollar coverage — they typically pay without a deductible but on a limited, scheduled basis. They split into separate building blocks:

• Basic hospital expense — room-and-board (a daily limit for a set number of days) plus miscellaneous hospital charges (lab, x-ray, drugs) up to a flat dollar cap.
• Basic surgical expense — pays surgeon fees on a surgical schedule (a fixed dollar amount per procedure) or by relative value (units multiplied by a conversion factor).
• Basic medical (physician) expense — pays non-surgical doctor visits, often capped per visit and per number of visits.

Because basic plans pay first dollar but cap quickly, a serious claim blows through the limits fast — which is exactly the gap major medical was created to fill.

Major Medical Cost-Sharing Mechanics

Major medical provides high maximum limits and broad coverage but uses cost-sharing so the insured has skin in the game. The four levers the exam tests:

Two structures appear: supplementary major medical (sits on top of a basic plan, with a corridor deductible between them) and comprehensive major medical (a single integrated plan with one deductible and coinsurance — the dominant modern form).

Worked Cost-Sharing Calculation

Assume a comprehensive major-medical plan: $1,000 calendar-year deductible, 80/20 coinsurance, and a $5,000 out-of-pocket maximum (the OOP max includes the deductible). The insured incurs $30,000 in covered charges.

1. Insured pays the first $1,000 (deductible). Remaining bill: $29,000.
2. Coinsurance applies 80/20: of $29,000, the insured's 20% share would be $5,800.
3. But the insured has already paid $1,000 toward the $5,000 OOP max, leaving only $4,000 of coinsurance exposure before the stop-loss triggers. The insured pays $4,000 in coinsurance, reaching the $5,000 cap.
4. The plan then pays 100% of all remaining covered charges for the year.

Insured's total cost = $1,000 + $4,000 = $5,000. The plan pays $25,000. Without the stop-loss the insured would have paid $6,800 — the OOP max saved $1,800.

Common traps:

• A corridor deductible in supplementary major medical applies between the basic plan's exhaustion and the major-medical layer — it is not the same as the initial deductible.
• Coinsurance is the insured's percentage; a copay is a flat dollar amount per service (e.g., $25 per office visit). The exam swaps these terms as distractors.
• The OOP max usually includes the deductible and coinsurance but historically excluded premiums and copays — read the question's stated rule.

Coinsurance, Copays, and the Common Accident Provision

Modern plans layer several cost-sharing terms that the exam tests as distractors. A copayment is a flat dollar amount per service, such as $30 per office visit, charged regardless of the bill size. Coinsurance is a percentage split applied after the deductible. A flat deductible applies once per cause or per year; a corridor deductible sits between a base plan's exhaustion and a supplementary major-medical layer. The common accident provision charges only a single family deductible when two or more family members are injured in the same accident, a small but frequently tested mercy clause.

Eligible Expenses and the Pre-Existing Condition Frame

Basic and major-medical plans pay only medically necessary charges for covered services, and they historically applied pre-existing condition waiting periods. Under the Affordable Care Act, individual and group major-medical plans may no longer impose pre-existing condition exclusions, but the exam still tests the legacy mechanics for older policy designs and for excepted-benefit products that ACA does not govern.

Worked Family Deductible and Coinsurance

A comprehensive plan has a $500 per-person deductible, a $1,500 family aggregate deductible, 80/20 coinsurance, and a $6,000 family out-of-pocket maximum. Three family members each incur $400 of charges, for $1,200 total. No single person reaches the $500 individual deductible, and the $1,200 has not met the $1,500 family aggregate, so the plan pays nothing yet and the family pays the full $1,200. Once cumulative covered charges cross the $1,500 family deductible, the 80/20 coinsurance begins, and once the family's own share reaches $6,000 the plan pays 100% for the rest of the year.

Limited and Excepted Benefit Plans

Additional Exam Traps

• A copay is a flat dollar amount; coinsurance is a percentage -- the item writer swaps them.
• The common accident provision triggers only one deductible for one event.
• The OOP maximum historically includes deductible and coinsurance but excludes premiums.
