Key Takeaways

• Your employer health coverage can impact your Medicare choices, so understanding how they work together is crucial.

• HR can provide essential details about your plan’s costs, coordination with Medicare, and what happens if you delay enrollment.

Is Your Employer Health Plan Creditable for Medicare Part B and Part D?

One of the first things you should ask your HR department is whether your employer-sponsored health coverage is considered “creditable” for Medicare Parts B and D. Creditable coverage means your employer plan is expected to pay, on average, as much as Medicare does. If your coverage is not creditable, you could face late enrollment penalties when signing up for Medicare later.

For Part B (Medical Insurance), some employer plans offer comparable outpatient benefits, but if your coverage is not creditable, you may need to enroll in Medicare Part B when first eligible.

For Part D (Prescription Drug Coverage), if your employer’s drug plan is not creditable, you might face a penalty if you enroll in Medicare Part D later than required. HR should provide a notice of creditable coverage each year. If you haven’t received it, ask for confirmation.

Will Your Employer Coverage Continue If You Enroll in Medicare?

Your employer’s size plays a major role in whether you need Medicare while still working. If your employer has 20 or more employees, your employer plan will remain the primary payer, and Medicare will be secondary. In this case, you may not need to enroll in Medicare immediately.

If your employer has fewer than 20 employees, Medicare generally becomes your primary coverage, and your employer plan becomes secondary. In this case, delaying Medicare could leave you with coverage gaps or higher out-of-pocket costs.

Your HR department should clarify how your employer plan coordinates with Medicare so you can make an informed decision about enrolling.

How Do Costs Compare Between Your Employer Plan and Medicare?

When deciding whether to keep your employer coverage or switch to Medicare, cost is a significant factor. Ask HR for details about:

• Monthly premiums for your employer plan compared to Medicare Part B.

• Deductibles and co-pays for doctor visits, hospital stays, and prescriptions.

• Out-of-pocket maximums to determine potential costs if you have significant medical expenses.

For 2025, the standard Medicare Part B premium is $185 per month, with an annual deductible of $257. Compare these figures with what you currently pay through your employer plan.

If your employer offers a Health Savings Account (HSA), enrolling in Medicare can impact contributions. You cannot continue contributing to an HSA once enrolled in Medicare, so ask HR how this affects your tax advantages.

What Happens to Your Dependents’ Coverage If You Enroll in Medicare?

If you switch to Medicare, your spouse or dependents could lose employer-sponsored health coverage if they rely on your plan. Some employers allow dependents to stay on the plan even if you transition to Medicare, while others do not.

HR should clarify whether:

• Your employer plan offers spousal or dependent coverage if you switch to Medicare.

• There are alternative options like COBRA or a separate employer-sponsored plan for dependents.

• Dependents would need to find coverage through the Health Insurance Marketplace or another source.

If your dependents require continued coverage, this could influence when you choose to transition to Medicare.

What Are the Consequences of Delaying Medicare Enrollment?

Delaying Medicare enrollment can have financial consequences, so it’s essential to understand how it applies to your situation. Ask HR about:

• Whether your employer coverage allows you to delay Medicare Part B without penalty.

• How losing employer coverage affects your ability to enroll in Medicare outside the Initial Enrollment Period.

• Whether COBRA coverage counts as creditable for delaying Medicare enrollment (in most cases, it does not).

The Initial Enrollment Period (IEP) for Medicare is a seven-month window that starts three months before you turn 65 and ends three months after your birthday month. If you delay Part B without creditable coverage, you may pay a 10% penalty for every 12 months you go without it.

For Part D, the penalty is 1% of the national base premium per month you go without creditable drug coverage. These penalties last for as long as you have Medicare, so it’s crucial to plan ahead.

What Are Your Options If You Retire Before or After Age 65?

If you plan to retire before Medicare eligibility at age 65, HR should explain your coverage options, such as:

• Whether your employer offers retiree health benefits until Medicare kicks in.

• If you can enroll in COBRA for temporary coverage and its associated costs.

• Whether you qualify for coverage through a spouse’s employer plan.

If you retire after 65, ask about:

• The Special Enrollment Period (SEP), which gives you eight months to sign up for Part B once your employer coverage ends.

• How to avoid penalties when transitioning from employer coverage to Medicare.

These answers will help you time your Medicare enrollment to avoid coverage gaps or unnecessary costs.

Making the Right Choice for Your Health and Finances
