Major Medical Insurance: Deductibles and Stop-Loss

Major Medical insurance is designed to provide broad coverage for catastrophic injuries and long-term illnesses. Unlike basic medical plans, which often have low limits and specific category restrictions, major medical policies feature high maximum benefits, often reaching into the millions. These plans are the cornerstone of the complete Health Insurance exam guide because they represent the standard modern approach to health coverage.

To manage the high cost of these benefits, major medical policies utilize cost-sharing mechanisms. The primary tools used are deductibles, coinsurance, and stop-loss provisions. Understanding how these elements interact is critical for passing the health insurance exam, as you will likely be asked to calculate out-of-pocket costs based on specific scenarios.

A deductible is the initial amount of covered medical expenses that an insured must pay out-of-pocket before the insurance company begins to pay benefits. In Major Medical policies, deductibles serve two purposes: they reduce the number of small, administrative-heavy claims and they lower the premium by shifting some initial risk to the insured.

There are several types of deductibles you must recognize:

• Flat Deductible: A specific dollar amount that must be met for each claim or for each year.
• Corridor Deductible: Used specifically with Supplemental Major Medical policies. This deductible applies after the basic plan benefits are exhausted but before the major medical coverage kicks in. It sits like a "corridor" between the two plans.
• Integrated Deductible: When a single deductible applies to both the basic medical coverage and the major medical coverage.
• Common Accident Provision: If multiple family members are injured in the same accident, only one deductible applies rather than individual deductibles for each person.

Once the deductible has been satisfied, the policy moves into the coinsurance phase. Coinsurance is a sharing of expenses between the insured and the insurer, typically expressed as a percentage. The most common split is 80/20, where the insurer pays 80% of the covered expenses and the insured pays the remaining 20%.

However, without a limit, a 20% share of a million-dollar bill would still bankrupt most individuals. This is where the Stop-Loss Feature (also known as the Out-of-Pocket Limit) becomes vital. The stop-loss is a specified dollar amount at which the insured's coinsurance obligation ends. Once the insured's out-of-pocket coinsurance costs reach this limit, the insurer pays 100% of all additional covered expenses for the remainder of the policy year.

Note: On many exams, the stop-loss limit refers specifically to the coinsurance amount, though in modern practice, it often includes the deductible as well. Always read the question carefully to see if the deductible is included in the "out-of-pocket maximum."
