If you’re turning 65 in the Hendersonville or Nashville area, you’ve likely noticed your mailbox is suddenly the most popular spot in town. It’s overflowing with glossy brochures, each one promising "the best" coverage. But here in Middle Tennessee, we like to keep things straightforward. When you strip away the marketing, the big decision usually comes down to two paths: Medicare Advantage or Medicare Supplement (Medigap).
As we look toward 2026, the landscape is shifting. Costs are changing, and new rules are coming into play. The big question remains: Which path actually saves you money?
The answer isn't a one-size-fits-all number. It’s about a fundamental tradeoff between predictability and monthly savings. Let's break down the 2026 figures so you can decide which path feels right for your wallet and your peace of mind.
The Fundamental Tradeoff: Savings vs. Certainty
Think of Medicare like a Nashville highway. Medicare Advantage (Part C) is like the lane with the low toll but occasional traffic jams. Medigap is like the express lane: you pay a higher fixed cost upfront, but the road ahead is wide open and predictable.
The Medicare Advantage Path
For 2026, the average Medicare Advantage premium is hovering around $11 per month based on recent CMS data. For many, that $0 or low-dollar premium is incredibly attractive. You save money every month on your fixed costs, which leaves more in your pocket for enjoying a morning at Drakes Creek Park or a coffee with friends.
The Medigap Path
Medigap plans, like the popular Plan G, have a higher monthly premium (often ranging from $120 to $180 depending on your age and location). You’re essentially prepaying for your healthcare. In exchange, you get a level of certainty that’s hard to beat. When you walk into a doctor’s office, you generally know exactly what you’re going to owe: nothing more than your annual Part B deductible.
Breaking Down the 2026 Hospital Costs
One of the biggest "gaps" in Original Medicare is the Part A hospital deductible. If you have a hospital stay in 2026, that deductible is $1,736.
If you are on the Medigap Plan G path, your plan covers that $1,736 in full. You could stay in the hospital for days and not see a bill for that deductible.
On the Medicare Advantage path, you typically pay a daily copay for hospital stays (e.g., $300 a day for the first five days). While this is often less than the full deductible for a short stay, it adds a layer of unpredictability. If you have multiple health events in a year, those copays can add up quickly toward your plan’s "Maximum Out-of-Pocket" limit.
The Part B Deductible: Your Only Homework on Plan G
If you choose the Medigap path, there is one small hurdle to clear each year: the Part B Deductible. In 2026, this is $283.
This is your annual "exposure." Once you pay that first $283 for doctor visits or outpatient services, Plan G kicks in and covers 100% of your remaining Medicare-approved medical bills for the rest of the year. For many of our clients in Hendersonville, having a "worst-case scenario" of just $283 plus their premiums is the ultimate peace of mind.
The IRMAA Reality: It’s Not the Same for Everyone
You might hear neighbors say, "Everyone pays the same for Medicare," but that's not quite true if you’ve had a successful career. If your modified adjusted gross income is over $109,000 (single) or $218,000 (joint), you may be subject to IRMAA (Income-Related Monthly Adjustment Amount).
IRMAA is a surcharge on your Part B and Part D premiums. It’s important to remember that IRMAA follows you regardless of which path you choose. Whether you are on a $0 premium Medicare Advantage plan or a $150 Medigap plan, Uncle Sam will still collect that surcharge if you fall into those higher-income brackets.
The "Switching Trap" in Tennessee
This is perhaps the most important piece of advice I give to my neighbors in Middle Tennessee: Your first choice matters.
In Tennessee, if you start with Medicare Advantage and decide a few years later that you’d rather have a Medigap plan, you typically have to go through medical underwriting. This means the insurance company can look at your health history. If you have pre-existing conditions: like heart issues, diabetes, or a history of cancer: they can charge you more or deny your coverage entirely.
While states like New York or Connecticut guarantee access to Medigap at any time, Tennessee does not. Starting with Medicare Advantage because it's "cheaper today" can sometimes trap you in that path later when your health needs (and costs) increase.
The 2026 Pharmacy Update: A Win for Everyone
There is good news for 2026, regardless of which path you choose. Thanks to new federal regulations, the Part D out-of-pocket cap is $2,100.
In the past, seniors with high-cost prescriptions could face unlimited "donut hole" spending. Starting in 2026, once you have spent $2,100 out of your own pocket on covered prescriptions, your cost-sharing drops to $0 for the rest of the year. This applies to stand-alone Part D plans (used with Medigap) and the drug coverage built into Medicare Advantage plans.
Which Path Saves You Money?
At Medi65, we aren't here to push you toward one specific company. We are independent brokers, which means we work for you, not the insurance carriers.
- Choose Medicare Advantage if: You are generally healthy, prefer a low monthly fixed cost, and don't mind staying within a specific network of Nashville-area doctors. You are comfortable with "pay-as-you-go" copays in exchange for that $11 average premium.
- Choose Medigap if: You want total predictability. You want to see any doctor in the country that accepts Medicare without a referral. You’d rather pay a higher monthly premium to ensure that a major health event won’t result in a surprise $5,000 bill.
Medicare is complex, but it doesn't have to be overwhelming. We’ve helped thousands of folks right here in Tennessee navigate these exact numbers to find the plan that fits their life and their budget.
