Should You Keep Health Insurance Through Your Employer or Switch to Medicare?
In this blog post, we’ll explore the key factors to consider when deciding whether to keep your employer-based health insurance or switch to Medicare. We’ll take a closer look at factors such as cost, coverages, network, and eligibility requirements to help you make an informed decision. By the end of this post, you should have a better understanding of the pros and cons of each option and be better equipped to make the right choice for your healthcare coverage.
Cost
Review the cost of your employer’s health insurance plan with the cost of Medicare. Medicare has monthly costs, deductibles, and co-pays, which may differ from your employer coverage.
Coverage
Review the coverage of your employer’s health insurance plan with Medicare. Medicare offers coverage including hospitalization, doctor visits, and prescription drug coverage. Some employer plans may offer additional benefits, such as vision and dental coverage.
Network & Eligibility
Confirm that your doctors are in-network and understand when Medicare enrollment applies to your situation.
How to Review the Costs of Your Employer Coverage to Medicare
To review the costs of your employer coverage with Medicare, conducting research can be helpful. Doing so can help you avoid late penalties for enrolling in Medicare and identify your most cost-effective plan. You can use our Medicare plan finder to get an overview of different plans, their costs, and coverage, and ensure you’re not paying too much for health insurance if you choose to keep your employer’s coverage. Additionally, one of our licensed insurance agents can assist you in determining the better option for your situation.
How Medicare Coordinates With Employer Coverage
If you work for a large company with 20 or more employees and have employer-sponsored group health insurance, you can combine Medicare with your employer’s coverage. Usually, your employer insurance is primary, and Medicare is secondary. Medicare Part A typically does not have a premium if you worked for at least ten years, which may help reduce out-of-pocket costs. Part B has a premium, so some people wait to enroll in Part B until they retire and their employer coverage ends. In that case, a creditable coverage letter from your employer is necessary to avoid late enrollment penalties.
If you are on COBRA coverage, Medicare pays first, and COBRA pays second. Reviewing your employer’s coverage compared to Medicare can help you understand if you are paying more than necessary. Once you turn 65, you must enroll in Medicare Parts A and B to avoid penalties.
Depending on your situation, dropping your employer coverage and enrolling in Medicare (with a Medigap or Medicare Advantage plan) may be an option. These plans may help manage out-of-pocket costs for deductibles and co-pays.
Reviewing each option carefully can help you make a neutral, informed decision about your coverage.
Medicare Rules for Employers With Fewer Than 20 Employees
If you work for a company with fewer than 20 employees, you generally must enroll in Medicare Parts A and B. Medicare is primary, and your employer’s group insurance is secondary. In some situations, you may be able to delay Part D enrollment if your employer plan includes prescription drug coverage.
Depending on your medical needs, Medicare with a Medigap or Medicare Advantage plan may be more cost-effective than your employer coverage. Review plans carefully to determine which coverage best meets your health and budget needs.
Check if your doctors and healthcare providers are in the network of your employer plan or Medicare. Some Medicare Advantage plans may have more restrictive provider networks than employer-based plans.
Make Sure You’re Not Overpaying for Health Insurance
- If your employer doesn’t contribute to your insurance coverage
- If your premiums, deductibles, or co-pays increase year over year
- If your healthcare needs or budget have changed
It is important to review your employer’s health insurance coverage against Medicare, including Medigap or Medicare Advantage. Reviewing your options can help ensure your coverage aligns with both your healthcare needs and financial goals.
Co-pay and Coinsurance Explained
Co-pay: A fixed dollar amount you pay when you use medical services, such as $45 for a doctor visit or $300 for an ER visit.
Coinsurance: A percentage of the cost of a service you pay after meeting your deductible. For example, a $200 doctor visit with 10% coinsurance would cost you $20, and the insurance pays $180.
A licensed insurance agent can help you understand these costs and review whether staying on your current employer plan or switching to Medicare may be more suitable for your situation.
Spouse Coverage Considerations
If your spouse’s employer provides coverage, the same rules generally apply. If your spouse works for a company with 20 or fewer employees, you will likely need to enroll in Medicare. If your spouse works for a company with more than 20 employees, you may be able to delay enrollment if it makes sense for your situation. Always review your coverage carefully to avoid penalties.
