Final answer:
An 80/20 coinsurance provision in a major medical policy indicates that the insurer pays 80% and the insured pays 20% of covered healthcare expenses after the deductible is met. This form of cost-sharing encourages policyholders to be more conscientious about their healthcare spending.
Step-by-step explanation:
The question revolves around the concept of coinsurance, which is commonly found in major medical policies. In such a provision, after the deductible has been met, the insurer and the insured share the cost of covered expenses at predetermined percentages. Specifically, an 80/20 coinsurance provision means that the insurer covers 80% of the covered expenses after the deductible has been paid, and the insured covers 20% of the costs. This form of cost-sharing is implemented to reduce moral hazard by ensuring that the insured party also has a financial stake in their healthcare costs. Coinsurance, along with deductibles and copayments, motivates policyholders to make prudent healthcare decisions, possibly leading to lower overall healthcare expenditures.
