Corridor deductible
A corridor deductible is the amount a patient pays out of pocket between the point where basic medical coverage runs out and the point where supplemental major medical coverage begins. It bridges the gap — or corridor — between the two plans.
A corridor deductible appears in superimposed (supplemental) major medical plans — arrangements that stack a major medical policy on top of a basic medical expense plan. The basic plan pays first, typically from the first dollar of covered expenses. Once its benefits are exhausted, the insured pays the corridor deductible out of pocket, and only then does the major medical policy begin paying.
The name describes its position: the deductible sits in the "corridor" between the two layers of coverage. For example, suppose a basic plan pays the first $5,000 of a hospital bill and the supplemental major medical plan carries a $500 corridor deductible. On a $15,000 claim, the basic plan pays $5,000, the insured pays the next $500, and the major medical plan then covers the remaining $9,500, subject to any coinsurance.
This structure differs from a flat deductible in a comprehensive major medical policy, where the insured pays the deductible before any benefits at all. With a corridor deductible, the insured gets first-dollar coverage from the basic plan and faces out-of-pocket cost only in the gap. After the corridor deductible is met, coinsurance provisions — commonly the insurer paying 80% and the insured 20% — usually apply to the remainder.
Corridor deductibles are a standard testing point on life and health insurance licensing exams. Within the medical expense insurance material, expect questions asking you to identify which deductible type applies between a basic plan and a supplemental major medical plan, or to calculate what each party pays on a claim like the example above.
Key takeaways
- A corridor deductible applies between exhaustion of a basic medical plan and the start of supplemental major medical benefits.
- The insured receives first-dollar coverage from the basic plan and pays out of pocket only in the corridor.
- After the corridor deductible, coinsurance (such as 80/20) typically applies to remaining covered expenses.
- Life and health licensing exams test corridor deductibles with claim-calculation questions in the medical expense insurance section.
