Key Takeaways
-
Medicare Supplement Plans, also known as Medigap, are designed to cover the gaps left by Original Medicare (Parts A and B) in 2025.
-
Understanding your options and the costs covered by Medigap plans can help you manage healthcare expenses effectively.
What Original Medicare Doesn’t Cover
Original Medicare (Parts A and B) is a great foundation for your healthcare coverage, but it doesn’t cover everything. While Part A (hospital insurance) and Part B (medical insurance) provide essential benefits, you’re still responsible for certain out-of-pocket costs. These include:
-
Deductibles: The 2025 deductible for Part A is $1,676 per benefit period, while Part B has an annual deductible of $257.
-
Coinsurance: For Part A, you pay $419 per day for hospital stays between 61-90 days and $838 per day for lifetime reserve days. Skilled nursing facility care requires $209.50 per day after the 20th day.
-
Excess Charges: If your doctor doesn’t accept Medicare’s approved amount, you may face additional fees.
-
Routine Services: Vision, dental, and hearing care are not covered by Original Medicare.
These gaps can add up, which is where Medicare Supplement Plans come in.
How Medicare Supplement Plans Work
Medicare Supplement Plans, or Medigap, are private insurance policies designed to work alongside Original Medicare. They help cover costs that Medicare doesn’t pay, such as:
-
Part A and B deductibles
-
Coinsurance and copayments
-
Excess charges from non-participating providers
It’s important to note that Medigap plans only work with Original Medicare. If you’re enrolled in a Medicare Advantage Plan (Part C), you can’t purchase a Medigap policy.
Standardized Plans for Simplicity
In 2025, Medicare Supplement Plans are standardized across most states. This means the benefits of each plan are the same no matter which company you purchase from. Plans are labeled A through N, each offering a unique set of benefits. Here’s a brief overview:
-
Plan A: Covers basic benefits like Part A coinsurance and hospital costs.
-
Plan F: Offers comprehensive coverage, including both Part A and Part B deductibles. However, it’s only available to those eligible for Medicare before January 1, 2020.
-
Plan G: Similar to Plan F but doesn’t cover the Part B deductible.
-
Plan N: A cost-effective option with lower premiums but includes some copayments.
Key Benefits of Medicare Supplement Plans
Predictable Healthcare Costs
With Medigap, you can better anticipate your medical expenses. For instance, plans that cover deductibles and coinsurance reduce the surprise of high out-of-pocket costs during a hospital stay.
Nationwide Coverage
Medigap plans provide coverage anywhere Original Medicare is accepted. Whether you’re traveling across the country or moving to a new state, your plan goes with you.
Guaranteed Renewability
As long as you pay your premiums, Medigap plans are renewable every year. This means you can’t lose coverage because of changes in your health status.
Flexibility with Providers
Unlike Medicare Advantage Plans, Medigap policies don’t limit you to a network of providers. You can see any doctor or specialist that accepts Medicare.
What Medigap Doesn’t Cover
While Medigap plans fill many gaps, they don’t cover everything. Notably, these plans do not include:
-
Prescription drugs (you’ll need a separate Part D plan)
-
Long-term care
-
Routine dental, vision, or hearing services
It’s essential to understand these exclusions so you can plan for additional coverage if needed.
Enrollment Periods and Eligibility
When to Enroll
The best time to enroll in a Medicare Supplement Plan is during your Medigap Open Enrollment Period. This is a six-month window that starts the month you turn 65 and are enrolled in Part B. During this time:
-
You’re guaranteed coverage regardless of pre-existing conditions.
-
Insurance companies cannot charge higher premiums based on your health.
Special Circumstances
If you miss your Open Enrollment Period, you may still be able to purchase a Medigap plan, but it could involve medical underwriting. This means the insurer can consider your health when determining eligibility and pricing.
Comparing Medigap Plans in 2025
When choosing a Medigap plan, consider the following factors:
-
Coverage Needs: Determine which out-of-pocket costs you want to eliminate.
-
Monthly Premiums: These vary depending on the plan and your location.
-
Future Needs: Consider how your healthcare needs might change over time.
Take advantage of resources like plan comparison tools or speak with a licensed Medicare advisor to help make an informed decision.
Medigap and Prescription Drugs
If you need prescription drug coverage, you’ll need to enroll in a standalone Medicare Part D plan. Medigap policies sold after 2006 do not include prescription drug benefits. Ensure your Part D plan aligns with your medication needs and budget.
Travel and International Coverage
Certain Medigap plans offer emergency medical coverage when traveling outside the U.S. For example, Plans C, D, F, G, M, and N cover 80% of emergency healthcare costs during the first 60 days of a trip, after you meet a $250 deductible. This can provide peace of mind for frequent travelers.
Costs to Consider in 2025
While Medigap helps reduce out-of-pocket expenses, it’s not free. Here are some costs to keep in mind:
-
Monthly Premiums: These vary based on your plan and location.
-
Part B Premium: You’ll still need to pay the Medicare Part B premium, which is $185 in 2025.
-
Part D Premiums: If you choose a standalone prescription drug plan, it will come with its own monthly premium.
How to Choose the Right Plan
Selecting the best Medigap plan requires careful consideration. Here are some tips:
-
Evaluate Your Healthcare Usage: Consider how often you visit doctors or specialists.
-
Compare Plans: Look at the benefits and costs of each plan.
-
Check Reviews: While plan benefits are standardized, customer service and ease of use vary by provider.
-
Ask Questions: Don’t hesitate to seek help from Medicare advisors or counselors.
Making the Most of Your Medigap Plan
Once you have a Medicare Supplement Plan, maximize its benefits:
-
Stay Informed: Understand your plan’s coverage and limits.
-
Keep Records: Maintain organized records of medical expenses and claims.
-
Review Annually: Reassess your plan during Open Enrollment to ensure it still meets your needs.
