Working Past 65?
The Working Senior Dilemma
Turning 65 used to mean an automatic shift into retirement, blowing out the candles, and signing up for Medicare. But today, things are completely different. Many of our neighbors are choosing to stay in the workforce well past 65.
If you plan to keep your employer group health insurance, you might think you can put Medicare on the back burner completely.
But beware: Staying on a work insurance plan without checking the fine print is one of the easiest ways to accidentally trigger a permanent, lifetime financial penalty on your Medicare Part B.
1. The “Magic Number” is 20 Employees
Whether you can safely delay Medicare Part B depends almost entirely on the size of the company you work for.
If your employer has 20 or more employees: Your job-based health insurance is generally considered “primary” coverage. In most cases, you can safely delay Part B without penalty because your employer plan remains your main shield.
If your employer has fewer than 20 employees: Stop right here. Medicare automatically becomes your primary insurer the month you turn 65, and your small group plan drops to secondary. If you don’t enroll in Part B, your work insurance can legally refuse to pay its share of your medical bills, leaving you exposed to 100% of the cost.
2. The COBRA & Retiree Insurance Illusion
This is the single biggest trap I see local seniors fall into. Someone retires at 64 and signs up for COBRA or transitions onto a corporate retiree health plan. Because the coverage is excellent, they assume they don’t need Medicare when they turn 65.
Here is the hard truth: According to the federal government, COBRA and retiree health plans do not count as active employer coverage.
If you stay on COBRA past age 65 without enrolling in Medicare Part B, your 7-month Initial Enrollment Window will close. When you finally try to sign up later, you will face the Part B Late Enrollment Penalty—a permanent 10% increase on your monthly premium for every 12-month period you delayed.
3. What is “Credible” Coverage?
To delay Medicare Part B safely, your employer coverage must be deemed “credible” (equal to or better than standard Medicare). Furthermore, you must prove that you or your spouse are actively working to maintain that coverage.
Keep documentation of your group coverage every year you work past 65. When you eventually choose to fully retire, you will need your employer to fill out Form CMS-L564 to prove you had active coverage, allowing you to bypass the late enrollment penalties during your Special Enrollment Period (SEP).
