Why Are Medicare Supplement Plans Called Medigap?

Posted on July 10th, 2026

 

 

Medicare Supplement plans are called Medigap because they fill the financial holes or gaps left behind by Original Medicare Part A and Part B.

 

While the federal government pays for many healthcare services, you remain responsible for significant out-of-pocket costs like deductibles and coinsurance payments.

 

The following details explain how these private insurance policies function to protect your savings from unpredictable medical bills.

 

The Specific Costs That Original Medicare Does Not Cover

Original Medicare provides a strong base for your healthcare but it was never designed to pay for every expense. You typically pay a monthly premium for Part B, yet you still face a 20 percent coinsurance fee for most doctor visits and outpatient services. This percentage can add up quickly if you require specialized treatments or frequent office visits throughout the year.

 

Hospital stays under Part A also come with a heavy deductible that you must meet before your coverage begins. This deductible is not a one-time annual fee. you might have to pay it multiple times if you are readmitted during different benefit periods. We see many Brooklyn residents surprised by these recurring charges when they thought their federal benefits covered everything.

 

Beyond deductibles, Original Medicare lacks an annual out-of-pocket maximum to limit your spending. Without a Medigap policy, there is no ceiling on how much you might owe in a single year for medical care. These gaps in coverage create financial uncertainty that many people prefer to eliminate through supplemental insurance.

 

Four Common Expenses That Medigap Policies Help Pay

  1. The Part A hospital deductible and coinsurance costs.
  2. The 20 percent coinsurance for Part B medical services.
  3. Blood work and transfusion costs for the first three pints.
  4. Skilled nursing facility care coinsurance after the initial 20 days.

 

These specific expenses represent the most frequent drains on a retiree's bank account. By choosing a policy that addresses these areas, you replace unpredictable bills with a steady monthly premium. This predictability allows you to budget your household expenses without fearing a sudden illness or injury.

 

Most Medigap plans also provide coverage for foreign travel emergency care which Original Medicare generally excludes. Having this protection means you can travel outside the United States with confidence in your medical backup. We focus on helping you identify which of these four areas matter most to your specific health situation.

 

How Private Insurance Works Alongside Federal Benefits

Medigap policies are sold by private companies like Shermanes Insurance Agency LLC rather than the federal government. You must have Original Medicare Part A and Part B to buy one of these plans. Once you have both, your private supplement stays in the background and pays its share after Medicare pays the primary amount.

 

This relationship is standardized by the government, meaning a Plan G from one company offers the same basic benefits as a Plan G from another. While the benefits stay the same, the premiums and customer service levels vary between providers. We help you compare these options to find a price point that fits your retirement goals.

"A Medigap policy ensures that your medical bills don't become a source of stress during your retirement years."

 

You keep your own doctors and specialists as long as they accept Medicare patients. There are no networks to worry about and you do not need referrals to see a specialist in most cases. This freedom of choice combined with financial protection is why so many people choose to add a supplement to their federal coverage.
