9.2 Medical Expense Insurance (Basic and Major Medical)
Key Takeaways
- Basic medical pays first-dollar (little/no deductible) but with low maximum limits.
- Major medical has high limits but applies a deductible and coinsurance.
- A comprehensive major medical plan combines basic and major medical under one deductible.
- The corridor deductible sits between basic benefits and supplemental major medical benefits.
- The carryover provision lets last-quarter deductible expenses apply to next year's deductible.
Medical expense insurance pays for the cost of treating illness and injury. Historically the market separated basic (first-dollar, limited) coverage from major medical (high-limit, broad) coverage; modern comprehensive plans blend the two. The exam still tests the traditional categories because they define the building blocks of any plan.
Basic Medical Expense Coverage
Basic plans pay benefits with little or no deductible but have low maximum limits. They are typically written on a scheduled or per-service basis.
| Basic Coverage | What It Pays |
|---|---|
| Hospital expense | Room and board (often a daily limit) plus miscellaneous hospital charges |
| Surgical expense | Surgeon fees, usually per a surgical schedule or relative-value scale |
| Physician (medical) expense | Non-surgical doctor visits, in or out of hospital |
Room and Board Trap
Basic hospital coverage often states a daily room-and-board benefit (e.g., $400/day for 90 days). If the actual semi-private room charge exceeds the daily limit, the insured pays the difference. The miscellaneous expense benefit (lab, X-ray, drugs) is frequently expressed as a multiple of the daily room benefit, such as 20× the daily rate.
Major Medical Expense Coverage
Major medical fills the gaps left by basic plans, providing high maximum limits and broad coverage for catastrophic costs, but applies a deductible and coinsurance.
Supplemental vs Comprehensive Major Medical
| Type | Structure |
|---|---|
| Supplemental major medical | Layers on top of a basic plan; covers expenses beyond basic limits |
| Comprehensive major medical | Single policy combining basic and major medical with one deductible |
Deductible Features to Know
- Calendar-year (all-cause) deductible — one deductible per year for all illnesses combined.
- Per-cause deductible — a separate deductible for each accident or illness.
- Carryover provision — expenses incurred in the last three months of the year that are applied to that year's deductible also carry over to satisfy the next year's deductible.
- Family (common) deductible — once two or three members each meet (or the family aggregate is met), the deductible is satisfied for the whole family.
- Corridor deductible — a deductible applied between basic benefits and major medical benefits in a supplemental design.
Worked Example: Carryover
An insured has a $1,000 calendar-year deductible. In October–December they incur $300 in covered expenses applied to the deductible. Under the carryover provision, that $300 also counts toward next year's $1,000 deductible, so on January 1 they need only $700 more before major medical pays.
Coinsurance and the Stop-Loss
After the deductible, major medical pays a percentage — commonly 80% — and the insured pays the remaining coinsurance (20%) until the stop-loss limit is reached, at which point the insurer pays 100% of remaining eligible charges. The stop-loss exists to cap the insured's exposure in a catastrophic year. On the exam, remember the order: deductible, then coinsurance, then stop-loss/out-of-pocket maximum, then 100% insurer payment.
Worked Coinsurance Example
Deductible: $1,000 (insured pays)
Covered bill after deductible: $50,000
Coinsurance 80/20 with $5,000 stop-loss
Insured 20% would be $10,000, but stop-loss caps it.
Insured's coinsurance stops at $5,000.
Total insured cost: $1,000 + $5,000 = $6,000
Insurer pays: $45,000
Exclusions and Limitations
Medical expense plans commonly exclude or limit cosmetic surgery (unless reconstructive), experimental treatment, on-the-job injuries (covered by workers' compensation instead), care for which a government program is liable, and routine care obtained outside the network in HMO designs.
Pre-existing condition exclusions, once common, are now prohibited in ACA-compliant plans — a frequent exam point. Short-term limited-duration and other non-ACA plans, however, may still impose them, so the answer depends on the plan type described in the question stem.
Benefit Designs, Usual & Customary, and a Combined Worked Problem
Beyond deductibles and coinsurance, the exam tests how a plan decides the allowed amount. Usual, customary, and reasonable (UCR) charges cap reimbursement at the prevailing fee for a service in a geographic area; any provider charge above UCR is the insured's responsibility on an indemnity plan, on top of coinsurance. In-network managed-care plans replace UCR with a negotiated/contracted rate, which is why staying in network lowers cost.
Scheduled vs. service benefits
- Scheduled (indemnity) benefit — pays a fixed dollar amount per service from a list (e.g., $1,200 for an appendectomy), regardless of actual charge.
- Service benefit — pays a percentage of the actual (or contracted) charge, the model used by major medical and managed care.
Combined worked example
An indemnity plan has a $500 deductible, 80/20 coinsurance to a $3,000 out-of-pocket maximum, and reimburses surgery at UCR. The insured incurs a $20,000 hospital bill, of which $2,000 exceeds UCR. The plan first removes the $2,000 excess (insured's responsibility), leaving $18,000 eligible. The insured pays the $500 deductible; 20% coinsurance on the remaining $17,500 would be $3,500, but the $3,000 OOP cap limits the insured's coinsurance to $2,500. Total insured cost = $500 + $2,500 + $2,000 excess = $5,000; the insurer pays $15,000. The $2,000 above UCR never counts toward the out-of-pocket maximum — a classic trap.
A final building-block note: comprehensive major medical uses one integrated deductible, while supplemental major medical sits on top of a basic plan and may apply a separate corridor deductible between the two layers. When a stem describes a small first-dollar basic benefit plus a high-limit overlay, it is testing the supplemental design, not a single comprehensive policy.
Under a major medical carryover provision, expenses applied to the deductible during the last three months of the year may also be used to satisfy which deductible?
