If you’re approaching 65 here in Middle Tennessee, you’ve probably heard the "horror stories" about Medicare penalties. Maybe you’ve chatted with a neighbor at the Hendersonville Farmers Market or after a service at your local church, and they mentioned a monthly charge that never goes away.
They aren't just telling tall tales. The Medicare Part D Late Enrollment Penalty (LEP) is very real, and for 2026, the numbers have shifted again.
I’m Nathan Wright, and at Medi65, my goal is to make sure you never have to pay a dime more than necessary for your healthcare. Most people think Medicare is just one big "enroll and forget" system, but the prescription drug portion (Part D) has a few hidden traps.
Let’s look at the most common mistakes I see Tennessee seniors making and exactly how you can dodge the 2026 lifetime penalty.
What Exactly is the Part D Late Enrollment Penalty?
Before we talk about the mistakes, we have to understand what we’re fighting against. The Part D penalty is an amount that’s added to your monthly Medicare drug premium.
Here is the kicker: It is a lifetime penalty.
Once you trigger it, you pay it for as long as you have Medicare drug coverage. It doesn’t "expire" after a few years. It follows you from plan to plan, even if you switch insurance companies.
The 2026 Math
Medicare (CMS) calculates the penalty based on a "National Base Beneficiary Premium." For 2026, that number is $38.99.
The penalty is 1% of that base premium for every full month you were eligible for Part D but didn’t have "creditable" coverage.
The 2026 Formula:
0.01 x $38.99 x (Number of months without coverage) = Your monthly penalty
The result is rounded to the nearest $0.10. While $0.40 or $3.00 a month might not sound like a lot today, over 20 years of retirement, that’s thousands of dollars out of your pocket for absolutely no extra benefit.
Mistake #1: The "I Don't Take Any Meds" Trap
This is the number one mistake I see in my office. A healthy 65-year-old from Gallatin or Goodlettsville comes in and says, "Nathan, I don't even take an aspirin. Why would I pay for a drug plan I don't need?"
It sounds logical, right? Why buy a "gas card" if you don't own a car?
But Medicare looks at Part D as "insurance," not just a discount card. If you wait until you actually need a prescription: say, five years from now: to sign up, you will be hit with a 60-month penalty.
How to dodge it:
Even if you take zero medications, you should typically enroll in the lowest-cost Part D plan available in Tennessee. Think of it as "penalty insurance." You pay a small monthly premium now to lock in your enrollment and avoid a massive, permanent penalty later when your health needs inevitably change.
Mistake #2: Losing Your "Notice of Creditable Coverage"
If you are still working past 65 and have health insurance through your employer, you might not need to sign up for Part D yet. Your employer's plan might be "creditable": meaning Medicare considers it just as good as a standard Part D plan.
However, Medicare doesn't just take your word for it.
Every year, usually in September or October, your employer is required to send you a Notice of Creditable Coverage. Many people mistake this for junk mail and toss it in the recycling bin.
The Risk:
When you eventually retire and go to sign up for Medicare, the Social Security Administration may ask for proof that you had coverage. If you can’t produce those letters or proof from your employer, they will assume you had no coverage and start the penalty clock from the day you turned 65.
How to dodge it:
- Create a "Medicare Folder": Every fall, look for that letter from your HR department.
- Verify Yearly: Just because your plan was creditable last year doesn't mean it is this year. Check the letter every single time.
- Digital Backup: Take a photo of the letter with your phone and save it in a secure folder.
Mistake #3: Assuming COBRA Protects You
This is a heartbreaking mistake because it often happens to people who are trying to do the right thing.
If you leave your job and take COBRA coverage, you might think you’re safe from penalties because you still have "insurance." While COBRA might have a drug component that is creditable, it is not considered creditable coverage for Medicare Part B (medical).
For Part D (drugs), it’s a gray area. If the COBRA drug coverage isn't officially "creditable," the penalty clock starts ticking the moment your active employment ends: even if you are paying for COBRA.
How to dodge it:
If you are on COBRA and over 65, book a free Medicare Strategy Call immediately. We need to look at your specific COBRA paperwork to ensure you aren't accidentally racking up months of penalties.
Mistake #4: The 63-Day Gap
Medicare gives you a little bit of grace, but not much. You can go up to 62 days without creditable coverage before the penalty starts. On day 63, the penalty is triggered for every month you were without coverage since your Initial Enrollment Period.
I often see this happen when someone moves to Tennessee from another state. They cancel their old plan, get busy unpacking boxes in their new Hendersonville home, and forget to pick up a new plan within that 63-day window.
How to dodge it:
If you are moving or losing employer coverage, treat your Medicare enrollment as a top priority. Don't wait until the two-month mark to start looking at options.
Is it Possible to Appeal a Penalty?
If you’ve already been hit with a notice from Medicare saying you owe a late enrollment penalty, don't panic. You have the right to ask for a "reconsideration" if you believe the penalty was assessed in error.
Common reasons for a successful appeal include:
- You actually had creditable coverage (like through the VA or an employer) but Medicare didn't know.
- You never received a notice from your employer telling you the coverage wasn't creditable.
- You qualify for "Extra Help" (a federal program that helps with drug costs).
At Medi65, we often help our clients navigate these appeals by gathering the right documentation to show Medicare that they played by the rules.
Why the 2026 Numbers Matter Now
As we move through 2026, the cost of living continues to be a topic at every dinner table in Tennessee. While the Part D penalty might seem like a small line item, Medicare's "National Base Beneficiary Premium" typically goes up over time.
Because the penalty is a percentage of that base rate, your penalty will actually increase every year that the national base rate goes up: even if the number of months you were "late" stays the same.
It’s a compounding cost that eats away at your Social Security check.

Your Simple Checklist to Avoid the 2026 Penalty:
- Check your mail: Look for "Notice of Creditable Coverage" every September.
- Don't skip Part D: Even if you don't take meds, get a "placeholder" plan.
- Watch the clock: Never go more than 62 days without drug coverage.
- Verify COBRA: Never assume COBRA is "good enough" for Medicare.
- Get a Review: Have a licensed professional look at your plan once a year.
Medicare Part D is changing rapidly, especially with the new rules coming out of the Inflation Reduction Act. Don't let an old mistake or a simple misunderstanding cost you for the rest of your life.
