In health insurance, what is commonly referred to as a 'corridor deductible'?

A 'corridor deductible' is a specific type of deductible that is triggered after an insured individual has incurred certain medical expenses above a predefined threshold but below the maximum out-of-pocket limit. This means that once the expenses surpass a specific amount, the corridor deductible will apply, and the insurance will kick in to cover a higher portion of subsequent costs.

This concept is particularly relevant in policies with more complex benefit structures, such as those that include both a basic plan and a supplemental or extended coverage plan. The corridor deductible ensures that the insured has to contribute to a defined amount before the full benefits of the insurance policy are realized. This method helps in balancing the cost-sharing between the insured individuals and the insurance provider.

Other options do not accurately describe the functionality of a corridor deductible. For instance, a deductible based on the number of visits implies a different structure altogether, while a deductible related to emergency care would be specific to that type of care, and a fixed dollar amount per year does not relate to the conditions under which a corridor deductible takes effect.
