What Happens to Your Medicare If You Keep Working Past 65?

Most people turning 65 in Daytona Beach believe that the moment they blow out the candles on their birthday cake, they have to jump onto Medicare. If you are still working and have health insurance through your job, that assumption could be a very expensive mistake. Whether you should enroll now or wait depends on a few specific rules that many Volusia County residents miss until it is too late.

This post is for the working seniors: those of you who are 65 or older but aren't ready to call it quits on your career just yet. We are currently on Day 26 of the Medicare Marathon, and today we are tackling one of the most common questions I get in my office: "Do I have to sign up for Medicare if I still have a job?"

The short answer is: maybe. The long answer involves looking at your current employer’s size, your costs, and your future plans. If you make the wrong move, you could end up with a lifetime late enrollment penalty or a massive medical bill that your work insurance refuses to pay.

The Reality for Working Seniors in Volusia County

I recently sat down with a client in Ormond Beach who had been working for a small local business for twenty years. He turned 65, kept working, and assumed his employer group plan would just keep on covering him like it always had. Six months later, he had a minor procedure, and the insurance company denied the claim.

Why? Because his employer had fewer than 20 employees. In the eyes of the insurance world, Medicare was supposed to be his primary payer the moment he turned 65. Since he hadn't enrolled in Part B, he was left holding a $4,000 bill that neither the insurance company nor Medicare would touch.

This isn't an isolated incident. Whether you are in Daytona Beach, Port Orange, or DeLand, the rules regarding Medicare and working past 65 are strict. You are essentially standing at a crossroads: you can stay on your employer insurance, switch entirely to Medicare, or try to blend the two. Let's break down how to choose the right path.

The Magic Number: Why 20 Employees Matters

When it comes to Medicare and employer coverage, the size of your company is the single most important factor. This is where most people get tripped up.

If Your Employer Has 20 or More Employees

If you work for a company with 20 or more employees (this includes most large corporations and government entities), your employer’s group health plan is considered primary. This means it pays your medical bills first, and Medicare (if you have it) pays second.

In this scenario, you usually have the option to delay Medicare Part B without any penalty. Since Part B comes with a monthly premium (which is $174.70 for most people in 2024), many people choose to wait until they actually retire to sign up. You can typically still enroll in Medicare Part A because it usually costs $0 for most Americans who have worked at least 10 years.

If Your Employer Has Fewer Than 20 Employees

This is the danger zone. If your company has fewer than 20 employees, Medicare is considered primary. This means Medicare is expected to pay first. If you don't sign up for Part B, your employer's insurance can legally refuse to pay for things that Medicare would have covered.

For small business employees in Daytona Beach, I almost always recommend enrolling in both Part A and Part B at age 65 to avoid a gap in coverage.

Comparing Employer Insurance vs. Medicare

Just because you can stay on your employer plan doesn't always mean you should. I often help clients perform a side-by-side comparison. Here is what we look at:

  1. Monthly Premiums: How much are you paying out of your paycheck for your work insurance? If you are paying $300 a month for a plan with a high deductible, switching to a Medicare insurance plan might actually save you money.
  2. Deductibles and Out-of-Pocket Max: Many employer plans have seen deductibles skyrocket. Medicare Supplement plans can often lower your actual "per-visit" cost significantly.
  3. Dependent Coverage: If your spouse is younger than 65 and is on your work plan, leaving that plan might leave them without insurance. This is a huge factor for many families in Volusia County.
  4. Prescription Drugs: You need to ensure your employer's drug coverage is considered "creditable." If it isn't as good as a standard Medicare Part D plan, you could face penalties later.

Common Medicare Mistakes for Working Seniors in Florida

Avoiding the pitfalls of Medicare requires more than just reading a brochure. Here are the most frequent errors I see:

  • Trusting the HR Department blindly: Most HR reps are great at their jobs, but they aren't Medicare experts. I’ve seen many employees given the wrong advice about when to sign up, leading to lifetime penalties.
  • Assuming COBRA counts as "active" coverage: If you retire and take COBRA, you must sign up for Medicare. COBRA does not count as "creditable coverage" to delay Part B. If you wait until COBRA ends to get Medicare, you will likely face a penalty and a gap in coverage.
  • Missing the Special Enrollment Period (SEP): Once you stop working or lose your employer coverage, you have an 8-month window to sign up for Part B. If you miss this, you can only sign up during the General Enrollment Period (January–March), and your coverage won't start until later.
  • Not checking the 20-employee rule: As mentioned, this is the most common cause of denied claims for seniors still in the workforce.

Frequently Asked Questions About Medicare and Working

Can I have both Medicare and my employer insurance?

Yes. If your employer has 20+ employees, your work insurance is primary and Medicare is secondary. If the employer has fewer than 20 employees, Medicare is primary and the work insurance is secondary. Having both can sometimes help cover gaps, but you must weigh the cost of the Part B premium.

What is "creditable coverage" for prescriptions?

Creditable coverage means your employer's drug plan is expected to pay, on average, at least as much as Medicare’s standard drug coverage. Your employer is required to send you a notice every year telling you if your coverage is creditable. Keep this notice! You'll need it to avoid Part D penalties later.

Will I be penalized if I wait until age 70 to enroll in Medicare?

Not if you have "creditable" coverage through an employer (or a spouse's employer) with 20 or more employees. You will get a Special Enrollment Period when you finally retire to sign up without any late fees.

Does my Health Savings Account (HSA) affect Medicare?

Yes. Once you enroll in any part of Medicare (even just Part A), you can no longer contribute to an HSA. If you want to keep putting money into your HSA, you may need to delay Medicare entirely.
