If you’re planning for retirement or currently on Original Medicare, you’ve likely asked yourself how to avoid those frustrating out-of-pocket costs. That’s where the best Medicare Supplement plans in 2025 come in. These private policies—also known as Medigap—can help pay what Medicare doesn’t cover, like deductibles, coinsurance, and more.
Skyline Benefit is your trusted Medicare insurance broker in California, helping you compare and enroll in the right Medicare Supplement plan based on your health needs and budget.
What Is Medicare Supplement Insurance (Medigap)?
Medicare Supplement Insurance is private insurance that fills the gaps left by Original Medicare. These standardized plans (labeled A–N) cover expenses like:
- Medicare Part A & B coinsurance
- Hospital deductibles
- Limited emergency care when traveling abroad
Each Medigap plan offers the same basic benefits regardless of the insurer, but prices and additional perks may vary.
What Are the 2025 Medicare Supplement Plan Costs?
Understanding how much Medicare Supplement Insurance costs in 2025 can help you budget more effectively and choose the right plan for your needs. While prices vary by location, age, tobacco use, and the insurance company you choose, here’s a general overview:
- Monthly Premiums: Most Medicare Supplement plans range from $100 to $250+ per month. Plans with more comprehensive coverage (like Plan G or Plan N) tend to cost more but reduce out-of-pocket expenses.
- High-Deductible Options: If you’re looking for a lower monthly premium, Plan G and Plan F offer high-deductible versions. In 2025, you’ll need to pay $2,870 out-of-pocket before coverage begins. These plans are ideal for people who want to lower monthly costs but are comfortable covering more upfront if they need care.
- Out-of-Pocket Maximums (for cost-sharing plans): While most Medigap plans don’t have a cap on your spending, Plan K and Plan L are the exceptions. These plans share costs with you but protect you with annual limits:
- Plan K: $7,220
- Plan L: $3,610
Once you hit the limit, the plan pays 100% of approved services for the rest of the year.
Who Should Consider the Best Medicare Supplement Plans in 2025?
You may want a Medicare Supplement plan if you:
- Want predictable medical costs with fewer surprises.
- Travel often and need nationwide coverage.
- Prefer to see any doctor that accepts Medicare (no networks or referrals).
Who Might Not Need Medigap?
You might consider other options if:
- You want dental, vision, or drug coverage (Medigap doesn’t include these)
- You prefer lower monthly premiums (Medicare Advantage may cost less)
- You’re okay with staying in-network and need extra benefits.
When to Enroll in a Medicare Supplement Plan
The best time to enroll is during your Medigap Open Enrollment Period, which lasts six months after you turn 65 and enroll in Medicare Part B. During this time:
- You can buy any plan without medical underwriting.
- You can’t be denied for pre-existing conditions.
You can apply anytime after that, but you may be subject to health screening unless you qualify for a guaranteed issue right. If you enroll in Part B late (such as during the General Enrollment Period), your Medigap Open Enrollment starts when your Part B becomes active.
