9.2 Medical Expense Insurance (Basic, Major Medical)

Key Takeaways

  • Basic medical expense coverage is first-dollar (no deductible) but low-limit, split into hospital, surgical, and physician expense.
  • Major medical adds a deductible and coinsurance in exchange for broad, high catastrophic limits and an OOP/stop-loss.
  • Comprehensive major medical integrates both layers into one deductible and coinsurance; supplemental major medical sits atop a basic plan via a corridor deductible.
  • Carryover and common-accident provisions soften deductible hardship across years and per-accident family claims.
  • Hospital indemnity pays a fixed amount per day to the insured regardless of actual cost — it is a supplement, not reimbursement.

The Two Historical Building Blocks

Medical expense insurance evolved from two layers that the exam still tests: basic medical expense coverage and major medical coverage. Understanding the original distinction explains why modern comprehensive plans look the way they do.

Basic Medical Expense Coverage

Basic plans provide first-dollar coverage — they pay from the very first dollar with no deductible — but only for specific, limited categories and up to low scheduled limits. The three classic basic coverages are:

Basic coverageWhat it paysTypical structure
Hospital expenseRoom/board and miscellaneous hospital chargesFlat daily room limit + dollar cap on misc.
Surgical expenseSurgeon's feesSurgical schedule (dollar amount per procedure) or relative value
Physician's (medical) expenseNon-surgical doctor visits, in-hospital callsPer-visit limit, capped number of visits

Because basic plans pay first dollar but cap benefits low, a catastrophic claim quickly exhausts the limits, leaving the insured exposed. That gap is exactly what major medical was designed to fill.

Major Medical Coverage

Major medical provides broad, high-limit catastrophic protection. Its defining features:

  • A deductible (the insured absorbs the first layer, unlike first-dollar basic plans)
  • Coinsurance (typically 80/20) sharing costs after the deductible
  • A high or unlimited maximum benefit (modern ACA plans prohibit annual and lifetime dollar limits on Essential Health Benefits)
  • A stop-loss / out-of-pocket maximum that ends coinsurance once reached

Trap: Basic = no deductible, low limits (first-dollar). Major medical = has a deductible and coinsurance but high limits. The exam contrasts these on the deductible feature.

Supplemental vs. Comprehensive Major Medical

There are two ways the two layers were combined:

  1. Supplemental major medical — sits on top of a separate basic plan; it begins paying after the basic plan's limits are exhausted, often after a corridor deductible.
  2. Comprehensive major medical — a single integrated policy combining first-dollar-style features with catastrophic limits, using one deductible and one coinsurance arrangement. This is the model most modern plans follow.

Key Major Medical Provisions

ProvisionFunctionExam point
DeductibleAmount before plan paysMay be per-cause or per-calendar-year
CoinsuranceCost split after deductibleCommonly 80/20 in-network
Stop-loss (OOP max)Ends insured coinsurancePlan then pays 100%
Corridor deductibleBridge between basic and supplemental major medicalApplied after basic limits exhaust
Carryover provisionLate-year deductible expenses credited to next yearReduces double-deductible hardship
Common accident provisionOne family deductible for injuries from a single accidentAvoids stacking deductibles

Worked Example — Comprehensive Major Medical

A comprehensive plan has a $1,000 deductible, 80/20 coinsurance, and a $5,000 OOP maximum. The insured has $30,000 of covered charges.

Deductible:            $1,000 (insured)
Remaining:             $29,000
Insured 20%:           $5,800
Running insured total: $1,000 + $5,800 = $6,800
Capped at OOP max:     $5,000
Insurer pays:          $30,000 - $5,000 = $25,000

The insured pays $5,000 (the OOP max); the insurer pays $25,000.

Hospital Indemnity — A Different Animal

Distinguish medical expense (reimbursement) plans from a hospital indemnity policy, which pays a fixed dollar amount per day of hospitalization regardless of actual charges. It is a supplement, not primary coverage.

Indemnity Worked Example

A hospital indemnity policy pays $250/day. The insured is hospitalized 4 days with a $20,000 actual bill. The policy pays 4 × $250 = $1,000 — paid directly to the insured, who still owes the real charges to their major medical plan and providers.

Deductible Types and How Major Medical Pays

After basic-versus-major-medical, the exam drills the deductible structures layered into major medical. Distinguish them precisely, because each changes how fast the insured reaches the point where coinsurance kicks in.

DeductibleHow it works
Flat / calendar-yearFixed amount per person per year before coverage
Family (aggregate)Combined family expenses satisfy one deductible
Per-causeSeparate deductible for each separate illness/accident
Corridor (in comprehensive)Deductible between basic benefits and major medical
CarryoverQ4 expenses applied to next year's deductible

Coinsurance and the Stop-Loss Reset

Comprehensive major medical pays a coinsurance share (commonly 80/20) above the deductible until the insured's payments hit the out-of-pocket (stop-loss) maximum, after which the plan pays 100% of covered charges. Worked case: a $1,500 deductible, 80/20 coinsurance, and a $5,000 stop-loss means the insured pays the $1,500 deductible plus 20% of the next charges until total out-of-pocket reaches $5,000 — then the plan covers the rest of the covered, in-network bills for the year.

Coordinating Basic and Major Medical Coverage

Historically a worker might carry a basic plan (first-dollar, low limits, no deductible) layered beneath a supplemental major medical plan that picked up where basic stopped, bridged by a corridor deductible. Comprehensive major medical later merged the two into a single contract with one deductible and coinsurance. The exam tests this evolution because it explains why some older policies pay surgical and hospital benefits with no deductible while large expenses route through a separate major-medical layer.

When a question contrasts a fixed-schedule basic benefit against a percentage-coinsurance major-medical benefit, the distinguishing feature is whether a deductible applies before the plan pays.
