9.2 Medical Expense Insurance (Basic and Major Medical)

Key Takeaways

  • Basic medical pays first-dollar hospital, surgical, and physician benefits but with low maximums.
  • Major medical adds a deductible, coinsurance, and high limits to cover catastrophic costs.
  • Supplemental major medical layers on basic coverage; comprehensive combines both under one deductible.
  • Deductible variations include calendar-year, family, carryover, and common-accident provisions.
  • The stop-loss (out-of-pocket maximum) caps insured coinsurance; check whether the deductible counts toward it.

Medical expense insurance pays the cost of treating illness and injury. Historically it evolved from narrow basic benefits into broad major medical coverage, and the exam tests how these layers fit together. Basic medical plans were the original products: they paid hospital, surgical, and physician expenses on a first-dollar basis (usually no deductible) but capped benefits at relatively low limits.

Basic Medical Expense Coverage

Basic plans separate benefits into distinct, limited categories:

Basic CoverageWhat It Pays
Hospital expenseDaily room and board up to a stated dollar limit; miscellaneous hospital charges as a multiple of the room rate
Surgical expenseSurgeon's fee, often per a relative-value or dollar schedule
Physician (medical) expenseNon-surgical doctor visits, in-hospital or office

Key Point: Basic plans pay first-dollar (no deductible) but run out quickly because of low maximums. They were designed as a layer beneath major medical.

Major Medical Insurance

Major medical provides broad, high-limit protection against catastrophic costs. Its defining features are a deductible, coinsurance, and a high overall maximum (often $1 million+ historically; modern ACA plans have no lifetime dollar cap on essential health benefits).

  • Supplemental major medical sits on top of a basic plan, picking up where basic limits end (the basic plan provides a "corridor").
  • Comprehensive major medical combines basic and major medical into one policy with a single deductible, giving some first-dollar coverage plus catastrophic protection.

Deductible Variations

Deductible TypeHow It Works
Flat / calendar-yearOne amount per insured per year before benefits begin
Per-occurrenceApplies separately to each illness or accident
Family deductibleAggregate cap; once total family expenses meet it, the deductible is satisfied for all members
Carryover provisionExpenses in the last 3 months of the year apply to next year's deductible
Common accidentOne deductible when multiple family members are injured in the same accident

The Coinsurance / Stop-Loss Mechanism

After the deductible, the insured and insurer share covered costs by coinsurance (e.g., 80/20). To protect the insured from open-ended exposure, the stop-loss limit (out-of-pocket maximum) caps the insured's coinsurance; beyond it the plan pays 100%.

Worked example — comprehensive major medical:

  • Covered charges: $50,000
  • Calendar-year deductible: $2,500
  • Coinsurance: 80/20
  • Stop-loss (out-of-pocket max, excluding deductible): $5,000

Step 1: Insured pays $2,500 deductible; $47,500 remains. Step 2: 20% coinsurance on $47,500 = $9,500, but the stop-loss caps insured coinsurance at $5,000. Step 3: Insured total = $2,500 + $5,000 = $7,500. Insurer pays $50,000 - $7,500 = $42,500.

Trap: Read whether the deductible counts toward the stop-loss. Many exam problems state the out-of-pocket maximum applies to coinsurance only, so add the deductible separately.

Hospital Indemnity and Other Limited Plans

Not all "medical" products reimburse actual charges. Hospital indemnity (hospital confinement) insurance pays a fixed daily benefit — for example $300 per day of confinement — regardless of the actual hospital bill. It is supplemental, not primary coverage, and the insured keeps any amount above the real cost. Limited plans such as accident-only, specified-disease (e.g., cancer), and dread-disease policies likewise pay defined benefits and do not satisfy ACA minimum essential coverage.

Exclusions and Limitations Common to Medical Plans

  • Cosmetic surgery (unless reconstructive after injury)
  • Experimental or investigational treatment
  • Injuries from war or while committing a felony
  • Care covered by workers' compensation
  • Self-inflicted injuries (subject to mental-health parity rules)

Common Provisions That Control Payment

Medical expense plans use several provisions the exam tests directly. The UCR (usual, customary, and reasonable) standard caps the amount a plan pays for a service in a region; charges above UCR may be billed to the patient by non-network providers. A per-cause vs. all-cause deductible determines whether each new illness restarts the deductible. Preventive care under ACA-compliant plans is covered with no cost-sharing, encouraging early detection that lowers long-run claims.

Key Point: Hospital indemnity pays a flat daily amount and is never coordinated; it can pay in addition to a comprehensive plan because it is fixed-sum, not reimbursement-based.

Basic, Major Medical, and the Cost-Sharing Cascade

Medical expense insurance questions reward you for knowing the order in which cost-sharing applies and how the older basic plans differ from comprehensive major medical. Basic plans pay first-dollar benefits for a narrow category (hospital, surgical, or physician) usually with no deductible but with low internal limits, and they were historically layered to fill gaps. Comprehensive major medical replaced that patchwork with a single plan featuring a deductible, coinsurance, and an out-of-pocket maximum that protects against catastrophic cost.

Walk the cascade in every claim problem: the insured pays the deductible first, then shares the next dollars through coinsurance (commonly 80/20) until the out-of-pocket maximum is reached, after which the plan pays 100 percent of covered charges. A stop-loss / out-of-pocket maximum is the consumer's catastrophic protection, while internal limits and exclusions cap the insurer's exposure.

TermRole in the cascade
DeductibleInsured's first-dollar share each year
CoinsurancePercentage split after the deductible
Out-of-pocket maxCaps the insured's total annual share

Exam Trap: Hospital indemnity pays a flat daily amount and is never coordinated, so it can pay in addition to a comprehensive plan because it is a fixed-sum, not a reimbursement-based, benefit. Do not apply the coordination-of-benefits rule to it.
