As you approach the age of 65, understanding your Medicare options becomes crucial for managing your healthcare needs. While Original Medicare (Part A and Part B) provides essential coverage, it doesn’t cover everything. This is where Medicare Supplement Insurance, commonly known as Medigap, comes into play. Medigap is designed to help cover some of the out-of-pocket costs associated with Original Medicare, such as copayments, coinsurance, and deductibles.
Supplementing Medicare: Do You Need a Medigap Plan for Additional Coverage?

What Is Medigap?
Medigap policies are sold by private insurance companies and are intended to supplement Original Medicare. To be eligible for a Medigap policy, you must already have Medicare Part A (Hospital Insurance) and Part B (Medical Insurance). These policies are standardized across most states, meaning a Plan G offered by one company provides the same basic benefits as a Plan G from another, though costs may vary.
Why Consider a Medigap Plan?
While Original Medicare covers many healthcare services, it leaves significant gaps that could lead to high out-of-pocket costs. Original Medicare lacks an out-of-pocket maximum, meaning there’s no limit to what you might have to pay in a year. Medigap policies help cap these potential expenses, offering peace of mind similar to other types of insurance.
How Does Medigap Work with Original Medicare?
Medigap policies are individual and require that you be enrolled in both Medicare Part A and Part B. Once you have a Medigap policy, Medicare pays its share of the approved healthcare costs first. Then, your Medigap policy pays its portion. This coordination helps reduce your out-of-pocket expenses.
What Does Medigap Cover?
Medigap plans can cover costs like copayments, coinsurance, and deductibles that Original Medicare doesn’t fully pay for. Some plans also offer benefits that Original Medicare does not, such as emergency medical care during foreign travel. However, Medigap policies generally do not cover services like long-term care, vision or dental care, hearing aids, or private-duty nursing.
Costs Associated with Medigap
While Medigap policies offer valuable coverage, they come with their own costs. You will pay a monthly premium to the private insurance company for your Medigap policy in addition to your monthly Medicare Part B premium. The pricing of Medigap policies varies based on the insurance company, the specific plan, and your location. It’s important to compare policies, as premium amounts differ by company even for the same plan.
Factors that can affect the cost of your Medigap policy include discounts for nonsmokers or married individuals, medical underwriting, and high-deductible options. Insurance companies typically increase premium amounts annually, so consider this when budgeting for your healthcare expenses.
Enrollment and Eligibility
The optimal time to buy a Medigap policy is during your six-month Medigap Open Enrollment Period, which starts when you’re both 65 or older and enrolled in Medicare Part B. During this period, you have a guaranteed issue right to buy any Medigap policy sold in your state, regardless of your health status. If you try to purchase a policy outside of this period, you might face higher costs or denial due to medical underwriting.
Alternatives to Medigap
Medigap differs from Medicare Advantage Plans (Part C), which are an alternative to Original Medicare. You cannot have both a Medigap policy and a Medicare Advantage Plan. Medicare Advantage Plans often have lower premiums than Medigap policies and may include additional benefits like prescription drug coverage, dental, and vision care.
For those unable to afford Medigap premiums, alternatives include programs offering Medicare cost assistance or considering a Medicare Advantage Plan that aligns with your budget and healthcare needs.
Considerations Before Purchasing Medigap
Before deciding on a Medigap policy, it’s essential to assess your healthcare needs and financial situation. Individuals must assess their medical needs, financial capabilities, and benefit costs when choosing a Medigap plan. Consider factors such as:
- The extent of coverage you need.
- The monthly premium and how it fits into your budget.
- The reputation and financial stability of the insurance company.
- Any additional benefits that might be important to you, like foreign travel emergency coverage.
Conclusion
Deciding whether you need a Medigap plan for additional coverage depends on your individual healthcare needs and financial circumstances. Medigap policies can offer significant savings by covering additional costs not covered by Original Medicare, providing peace of mind and financial protection against unexpected medical expenses. It’s crucial to review and compare Medigap plans to understand coverage, costs, and how they integrate with other Medicare coverage.
