Medigap Plan G vs High-Deductible Plan G: What’s the Difference and Which Is Right for You?
Two plans. One big decision. Are you choosing the right Medigap coverage before age 65?
As you approach Medicare eligibility, you’ll quickly learn that not all supplement plans are created equal. For many seniors, Medigap Plan G and High-Deductible Plan G (HDG) top the list of options. But what’s the real difference—and how do you know which one makes the most sense for you?
This post is for those who are 6 months away from turning 65 and want to understand the real-world differences between these two popular plans. We’re breaking it down with clarity, examples, and actionable insights—without the fine print headache.
Medigap Plan G vs High-Deductible Plan G: What You Need to Know What is Medigap Plan G?
Medigap Plan G is one of the most comprehensive Medicare Supplement Insurance plans available. It covers nearly all out-of-pocket costs that Original Medicare (Parts A and B) doesn’t—except for the Part B deductible.
Plan G covers:
- Part A coinsurance & hospital costs
- Part B coinsurance/copayments
- Skilled nursing facility care
- Foreign travel emergency coverage
- Part A deductible
- Excess charges
What is High-Deductible Plan G?
High-Deductible Plan G (HDG) offers the same benefits as regular Plan G, but only after you meet an annual deductible—which is much higher than Plan G’s.
For 2025, the deductible is$2,870 (adjusted annually).
Until that deductible is met, you pay 100% of covered services out-of-pocket. After you hit the deductible, the plan covers everything that standard Plan G would.
Real-World Example: Who Chooses What?
Meet Don and Judy—both turning 65.
- Don is a healthy, active 65-year-old on a tight budget. He rarely visits the doctor, takes no prescriptions, and doesn’t want to overpay for coverage he may not use. He chooses High-Deductible Plan G, saving on monthly premiums while accepting a higher out-of-pocket risk.
- Judy takes a few medications, sees a specialist regularly, and wants predictability. She opts for regular Plan G—paying a bit more each month, but hardly any bills after that. It gives her peace of mind.
The takeaway: Both plans offer the same coverage, but they serve different financial strategies and risk tolerances.
