9.2 Medical Expense Insurance (Basic and Major Medical)

Key Takeaways

  • Basic medical expense plans pay first-dollar benefits but cap amounts by hospital, surgical, and physician schedules.
  • Major medical plans add deductibles, coinsurance, and high maximums for catastrophic protection.
  • Supplementary major medical layers on a basic plan; comprehensive major medical integrates both in one policy.
  • Deductibles vary: calendar-year, per-cause, family, corridor, and carryover types.
  • A carryover provision applies last-quarter expenses to the next year's deductible to avoid penalizing late-year claims.

Medical expense insurance reimburses or pays for the costs of treating sickness and injury. Historically it developed in two layers: basic medical expense plans that paid first-dollar benefits for specific services, and major medical plans that layered broad catastrophic protection on top. Modern comprehensive plans merge both layers, but the exam still tests the distinct mechanics of each.

Basic Medical Expense Plans

Basic plans are characterized by first-dollar coverage (no deductible) but limited benefit amounts. They typically come as separate coverages:

  • Hospital expense - pays room and board up to a daily limit for a set number of days, plus miscellaneous hospital charges (often a multiple of the daily room rate).
  • Surgical expense - pays surgeon fees per a surgical schedule (a dollar amount assigned to each procedure) or on a relative value basis using conversion factors.
  • Physician (medical) expense - pays for non-surgical doctor visits, often capped per visit and per year.

How Basic Benefits Are Calculated

Because basic plans pay against schedules, the insured bears any excess. A surgical schedule assigns a fixed dollar amount to each procedure (e.g., $1,200 for an appendectomy); if the surgeon charges $1,800, the insured pays the $600 difference. A relative value schedule instead assigns unit values to procedures and multiplies them by a conversion factor (dollars per unit), letting the schedule scale with inflation by adjusting one number.

Hospital expense benefits commonly express miscellaneous charges as a multiple of the daily room rate - for example, "20 times the daily board" for lab, drugs, and supplies. Because these caps are low relative to modern costs, basic plans alone leave large gaps, which is precisely why major medical developed as an overlay. The exam expects you to recognize that basic plans trade first-dollar convenience for inadequate limits.

Major Medical Plans

Major medical coverage provides high maximum benefits for a broad range of services and introduces the cost-sharing structure now standard in the market: an annual deductible, coinsurance, and a stop-loss/out-of-pocket maximum. Two forms appear on the exam:

  1. Supplementary major medical - sits on top of a basic plan, picking up where basic limits are exhausted, often after a corridor deductible between the two layers.
  2. Comprehensive major medical - a single integrated policy combining first-dollar features with high catastrophic limits; this is the dominant form today.

Deductible Variations

Deductible typeHow it works
Calendar-year (all-cause)Resets each January 1; all covered expenses accumulate
Per-causeApplies separately to each unrelated illness/injury
FamilyAggregate limit; once met, family deductible satisfied
CorridorBridges a basic plan and supplementary major medical
CarryoverQ4 expenses apply to next year's deductible

Worked Example: Major Medical with Carryover

An insured has a comprehensive major medical plan: $1,000 calendar-year deductible, 80/20 coinsurance, $5,000 out-of-pocket maximum, with a carryover provision. In November the insured incurs $800 of covered expenses (under the $800 carryover window). Those $800 apply to both the current year and toward the next year's deductible.

The next year, the insured needs only $200 more ($1,000 - $800 carried over) to satisfy the new deductible. After that, 80/20 coinsurance applies until the $5,000 out-of-pocket maximum is reached.

Common trap: The carryover provision only applies to expenses incurred in the last three months of the year and only if the deductible was not already met. It prevents an insured from being penalized for late-year claims that would otherwise reset uselessly.

Service Plans vs. Reimbursement Plans

Two delivery philosophies underlie medical expense coverage:

  • Reimbursement (indemnity) plans pay the insured (or reimburse) after a covered expense, subject to deductible, coinsurance, and usual, customary, and reasonable (UCR) limits. The insured may use any provider and bears balance-billing risk.
  • Service plans (e.g., Blue Cross/Blue Shield historically, and managed care) contract directly with providers, who agree to accept the plan's payment as payment in full. The plan pays the provider, not the insured.

Common Cost-Sharing Terms

TermMeaning
DeductibleFixed amount the insured pays before benefits begin
CoinsurancePercentage split after the deductible (e.g., 80/20)
CopaymentFlat fee per service (e.g., $30 office visit)
Out-of-pocket maximum / stop-lossAnnual cap on insured cost-sharing; plan then pays 100%

Trap: Premiums never count toward a deductible or out-of-pocket max, and a copay is a flat dollar amount while coinsurance is a percentage — the exam deliberately blurs these.

Usual, Customary, and Reasonable (UCR) Limits

Reimbursement plans cap payment at the usual, customary, and reasonable charge — the prevailing fee for a given procedure in a given geographic area. If a provider charges above UCR, the insured pays the excess unless the provider is in-network and bound by a negotiated fee schedule.

This is why network participation matters: an in-network provider accepts the plan's allowed amount as payment in full and cannot balance-bill the difference, while an out-of-network provider can bill the patient for charges above UCR. Recognizing UCR as the indemnity-plan payment ceiling — and the network hold-harmless rule as the consumer protection against balance billing — resolves many medical-expense scenario questions.
