Medicare Supplement

Example

“Martha purchased a Medicare Supplement Plan G to cover the 20% coinsurance that Medicare Part B doesn't pay, giving her more predictable healthcare costs.”

Memory Tip

Think 'Supplement means Support' - these plans support Original Medicare by paying for the costs Medicare leaves behind.

Why It Matters

Medicare Supplement insurance provides financial predictability and protection from high out-of-pocket medical costs that Original Medicare doesn't cover. Without supplement coverage, beneficiaries could face significant expenses from the 20% coinsurance, deductibles, and other cost-sharing requirements of Medicare.

Common Misconception

Many people confuse Medicare Supplement plans with Medicare Advantage plans, thinking they're the same thing. In reality, Supplement plans work with Original Medicare to pay additional costs, while Advantage plans replace Original Medicare entirely. Also, people often don't realize that Supplement plans don't include prescription drug coverage.

In Practice

Frank has Original Medicare and a Plan G supplement policy costing $125 monthly. When he has outpatient surgery costing $10,000, Medicare Part B pays 80% ($8,000) after he meets his deductible. His Plan G supplement pays the remaining 20% coinsurance ($2,000), so Frank's only out-of-pocket cost is his annual Part B deductible of $203. Without the supplement, he would have paid $2,203 instead of just the deductible.

Etymology

The term 'supplement' reflects its purpose to supplement or fill in the gaps left by Original Medicare coverage, providing additional financial protection for healthcare costs.
