What is the primary purpose of a deductible in a medical expense insurance policy?

• A. To share initial costs with the insured and reduce premium costs; benefits begin after the deductible is satisfied.
• B. To cap the total benefits at a fixed amount each year.
• C. To determine whether expenses are medically necessary.
• D. To provide unlimited coverage from day one.

Answer: (A)

The deductible represents cost sharing: the insured pays a portion of initial medical costs out of pocket, and only after meeting that amount do the insurer begins to pay benefits. This setup helps keep premiums lower because the insurer isn’t covering the early, predictable costs for everyone. Once the deductible is satisfied, the policy typically pays according to its coinsurance or copay structure, and the insured’s remaining cost-sharing continues as defined by the plan. This isn’t about determining medical necessity, nor about capping benefits, nor about providing unlimited coverage from day one—those aspects are governed by different features of the policy.
