Have a Large HSA Balance and Getting Ready for Medicare?
High-Deductible Plan G and HSA planning may deserve a closer look before you automatically choose a standard Plan G.
If you already have a substantial HSA balance, you may be in a very different position than someone entering Medicare with little money set aside for healthcare.
The real question is not simply which Medicare Supplement has the lowest deductible. It is whether paying a higher monthly premium for standard Plan G makes sense when you already have money available to cover healthcare expenses yourself.
Your HSA balance, the premium difference between the two plans, and your comfort with out-of-pocket costs all matter.
The Quick Answer
Standard Plan G and High-Deductible Plan G provide the same core Medigap benefits once the High-Deductible Plan G deductible has been met.
High-Deductible Plan G and HSA vs. Standard Plan G
Standard Plan G generally has a higher monthly premium and lower out-of-pocket exposure. High-Deductible Plan G generally has a lower monthly premium, but you pay Medicare-covered costs until the annual high deductible is met.
Once the High-Deductible Plan G deductible is met, the plan provides the same core Medigap benefits as standard Plan G for the rest of that calendar year.
Illustrative example only. Actual premiums vary by age, carrier, location, and other rating factors.
Why Your HSA Balance Matters
What Happens in a Bad Healthcare Year?
In a year with higher healthcare costs, you could be responsible for more out-of-pocket spending before High-Deductible Plan G begins paying its Medigap benefits.
Could the Premium Savings Make Sense?
If the premium difference between standard Plan G and High-Deductible Plan G is significant, the savings may help offset some or all of the additional out-of-pocket risk you are taking on.
Who May Be a Good Fit for High-Deductible Plan G?
This approach may appeal to people who have a strong HSA balance, can comfortably handle a higher deductible, and would rather keep more of their money than pay a higher monthly premium for standard Plan G.
Who May Prefer Standard Plan G?
Standard Plan G may be a better fit for someone who values predictable healthcare costs, does not want to manage a larger deductible, or simply prefers paying more each month in exchange for less out-of-pocket exposure.
Can You Use Your HSA With Medicare?
You can generally use existing HSA funds for qualified medical expenses after you enroll in Medicare, but you can no longer contribute to an HSA once Medicare coverage begins.
What Happens to Your HSA After You Enroll in Medicare?
Your existing HSA does not disappear when Medicare starts. You can continue using the balance for qualified medical expenses, including certain Medicare-related costs, but new HSA contributions generally must stop once you are enrolled in Medicare.
Compare the Numbers Before You Decide
The best way to evaluate standard Plan G versus High-Deductible Plan G is to compare the actual premium difference with the deductible risk and your available HSA balance. The answer can look very different from one person to the next.

Common Questions
What Is the 2026 High-Deductible Plan G Deductible?
In 2026, the High-Deductible Plan G deductible is $2,950. You pay Medicare-covered costs up to the deductible amount before the policy begins paying its Medigap benefits.
Can I Use My HSA to Pay High-Deductible Plan G Expenses?
You can generally use existing HSA funds tax-free for qualified medical expenses. That can make an HSA useful for covering eligible out-of-pocket healthcare costs while you are enrolled in High-Deductible Plan G.
What Is the Main Difference Between Standard Plan G and High-Deductible Plan G?
Standard Plan G generally has a higher monthly premium and lower out-of-pocket exposure. High-Deductible Plan G generally has a lower monthly premium, but you pay Medicare-covered costs until the annual high deductible is reached.
What Happens If I Have a Bad Healthcare Year?
With High-Deductible Plan G, you could have significantly more out-of-pocket spending during the year before the policy begins paying its Medigap benefits. That is why the premium savings and your ability to comfortably handle the deductible should be considered together.
Who Might Consider High-Deductible Plan G?
It may be worth considering if you have a substantial HSA balance or other savings, can comfortably handle higher out-of-pocket costs, and prefer paying a lower monthly premium rather than paying more for the predictability of standard Plan G.
Can I Keep Contributing to My HSA After I Enroll in Medicare?
Generally, no. Once you are enrolled in Medicare, you are no longer eligible to contribute to an HSA. You can keep the money already in the account and continue using it for qualified medical expenses.
