Creditable Coverage For Medicare

  • Medicare with Melissa

The world of health insurance is filled with terminology to decode, guidelines to adhere to, and crucial choices to make. One such term that stands out is “creditable coverage”. For anyone preparing to enroll in Medicare, grasping the implications of this term is extremely important. An understanding of creditable coverage can shield you from potential penalties and unwelcome coverage gaps. This term is especially relevant when it comes to Medicare Part B and Part D. By familiarizing yourself with the specifics of creditable coverage, you can optimize your healthcare benefits and ensure that your hard-earned money is put to the best use.

Understanding Creditable Coverage

First and foremost, what is creditable coverage for Medicare? Creditable coverage refers to a health insurance plan that provides the same or better benefits than those provided by the Medicare plan. The concept of creditable coverage plays a significant role in determining whether you’ll be penalized for late enrollment in Medicare Part B or Part D. If you are penalized, the penalty is added to your Medicare premium and applies for as long as you have Medicare coverage.

An essential element to remember is that not all health insurance is deemed creditable. For example, health insurance plans that offer only limited benefits, such as vision or dental insurance, or certain types of accident or disability insurance, are generally not considered creditable coverage. Moreover, foreign health insurance is typically not deemed creditable by Medicare.

Types of creditable coverage can include, but are not limited to, group health plans from an employer or union (including retiree plans), TRICARE, Federal Employees Health Benefits Program (FEHBP), Veterans’ Benefits, and health insurance from an individual market health plan.

A particularly relevant example is if you’re still working past the age of 65 and have health insurance from your employer. In this situation, the health insurance coverage you receive could be classified as creditable coverage, indicating that it meets or surpasses the requirements of Medicare Part B or Part D. As a result, you might decide to postpone enrolling in Medicare until either you retire or your employer coverage is terminated.

Significance of Creditable Coverage

Creditable coverage plays a significant role in the Medicare universe, particularly when it comes to Medicare Part B and Part D. By understanding this, you can make more informed decisions about when to enroll and how to avoid unnecessary penalties.

Medicare Part B primarily covers medical services and supplies deemed medically necessary, including outpatient care, preventive services, ambulance services, and durable medical equipment. It also covers part-time or intermittent home health and rehabilitative services, such as physical therapy, prescribed by a doctor to recover or improve functionality.

Creditable coverage is essential for Part B because it can influence when you decide to enroll and whether you’ll face a late enrollment penalty. For example, if you’re still employed when you turn 65 and have a group health insurance plan through your employer, your employer’s insurance could be considered creditable coverage. In this case, you can delay enrolling in Part B without incurring a late enrollment penalty if you apply within eight months of leaving your job or losing your employer coverage.

It’s crucial to note that small group health plans with fewer than 20 employees may not offer creditable coverage, so it’s always important to confirm with your benefits administrator.

Medicare Part D is all about prescription drug coverage. It helps cover the cost of prescription drugs and may lower your prescription drug costs and help protect against higher costs in the future.

The concept of creditable coverage is particularly important for Part D because, unlike Part B, Part D enrollment is not automatic for most people. When you’re first eligible for Medicare, if you don’t join a Medicare Prescription Drug Plan (Part D), a Medicare Advantage Plan (Part C), or another Medicare health plan that offers Medicare prescription drug coverage, you could face a late enrollment penalty unless you have creditable prescription drug coverage.

For example, if you’re covered by an employer or union group health plan that provides prescription drug coverage as good as or better than Medicare’s prescription drug coverage, that’s creditable coverage. You can keep that plan if it’s still available and join a Medicare drug plan without a penalty if you ever lose the employer or union coverage.

Understanding the implications of creditable coverage for Medicare Part B and Part D can save you from unnecessary stress and additional costs. It allows you to make smarter decisions about when to enroll, what other health coverage to maintain, and how to steer clear of late enrollment penalties. These penalties can apply throughout the duration of your Medicare coverage, so it’s important to ensure this doesn’t happen to you.

Letter of Credible Coverage

One of the most crucial pieces of documentation in the world of Medicare is the letter of credible coverage. Understanding what this is, how to get it, and why it’s important can save you a lot of headaches and possibly extra charges down the line. Here’s what you need to know.

The letter of credible coverage is a document provided by your health insurance plan that confirms you had creditable coverage under that plan. It’s often a simple letter or form that outlines the details of your coverage, including the start and end dates and the type of coverage provided. You may also see this document referred to as a ‘certificate of credible coverage’ or ‘proof of coverage’.

Obtaining this letter should be a priority when you’re about to leave an insurance plan, be it due to changing jobs, retiring, or transitioning into Medicare. To get this letter, you typically need to request it from your health insurance provider. Some providers might automatically send it to you when you leave the plan, but it’s always a good idea to ask for it proactively.

This letter of credible coverage is essentially your proof of previous insurance when you sign up for Medicare. If you delay enrolling in Medicare Part B or Part D because you have creditable coverage elsewhere, you will need this letter when you do decide to enroll. It serves as proof that you were adequately covered during the period you weren’t enrolled in Medicare, helping you avoid late enrollment penalties.

It’s important to keep a secure copy of this letter. Consider creating both digital and physical backups to ensure you have it when needed. If you misplace it or can’t obtain it for some reason, try to gather other documentation that shows you had health coverage, such as insurance cards, explanation of benefits statements from your insurer, or W-2 and tax statements showing you had coverage.

Ultimately, the letter of credible coverage is a key piece of documentation in the Medicare landscape. Ensuring you have it and understand its purpose can make your transition to Medicare smoother and help you avoid unnecessary penalties.

Medicare Supplement Insurance (Medigap)

When it comes to healthcare costs that are not covered by Original Medicare, Medicare Supplement Insurance, also known as Medigap, steps in. Understanding how Medigap ties into the concept of creditable coverage can further equip you to make optimal healthcare decisions.

Medigap policies are designed to fill the ‘gaps’ in Original Medicare coverage. These are the out-of-pocket costs you’d otherwise have to pay, such as copayments, coinsurance, and deductibles. Medigap policies are sold by private insurance companies and can vary in terms of what they cover and how much they cost.

In the context of creditable coverage, Medigap policies are typically considered creditable coverage for Medicare Part B, but not for Medicare Part D. This is because most Medigap policies sold today don’t include prescription drug coverage. If you have a Medigap policy that includes drug coverage, that coverage is usually not as comprehensive as Medicare Part D, and therefore is not considered creditable.

For this reason, if you have a Medigap policy and want comprehensive prescription drug coverage, you should consider enrolling in a separate Medicare Part D plan. If you delay enrolling in Part D and don’t have other creditable prescription drug coverage, you could face a late enrollment penalty.

Also noteworthy is the fact that if you have a Medigap policy with prescription drug coverage, and you decide to join a Medicare Part D plan, you must notify your Medigap insurance company and ask them to remove the drug coverage from your Medigap policy. If you don’t do this, you may lose your entire Medigap policy, not just the prescription drug coverage.

Medicare Enrollment Periods

There are three key Medicare enrollment periods: the Initial Enrollment Period (IEP), the General Enrollment Period (GEP), and the Special Enrollment Period (SEP).

The Initial Enrollment Period is a seven-month window that begins three months before the month you turn 65, includes the month you turn 65, and ends three months after the month you turn 65. This is the first chance you must enroll in Medicare, and it’s a critical time frame.

Enrolling in Medicare Part B and Part D during this period helps you avoid late enrollment penalties. However, if you have creditable coverage from an employer or union group health plan at this time, you might delay Part B or Part D enrollment without penalty.

If you didn’t sign up for Medicare Part B when you were first eligible, you can sign up during the General Enrollment Period between January 1 and March 31 each year. Your coverage won’t start until July 1 of that year, and you might have to pay a late enrollment penalty.

The Special Enrollment Period applies if you delayed Medicare enrollment at 65 because you had creditable health coverage from an active employer or union. In this case, you have an eight-month Special Enrollment Period to sign up for Medicare Part B, starting the month after your employment ends or the month after group health plan insurance based on current employment ends, whichever comes first. The SEP allows you to enroll in Medicare without facing late enrollment penalties.

Similarly, for Part D, you have a two-month Special Enrollment Period to enroll in a Medicare prescription drug plan without penalty after your creditable prescription drug coverage ends.


As you approach the age of eligibility for Medicare, understanding the intricacies of creditable coverage becomes incredibly important. It affects when you need to enroll in Medicare and whether you’ll face penalties for late enrollment.

Remember, creditable coverage is any insurance that offers the same or better coverage as Medicare. Make sure to get a letter of credible coverage when you leave any health plan, keep your notices of creditable coverage, and understand how this all plays into your Medicare Part B and Part D choices.

Meet Melissa MacCalla

Medicare is not simple and can be hard, frustrating, and downright confusing for most. I love when I get someone on the phone and I am given the opportunity to explain the difference in plans to them and have Medicare make sense. I enjoy talking to clients year after year, hearing about their families growing or them asking about mine.


Oh my gosh!! I was so confused about the Medicare Supplement process. I am turning 65 soon and am retired and have always had insurance thru my former employer. I didn’t know a thing about going on Medicare and was struggling to sort it all out.

She explained the steps I needed to take, gathered my information, helped me choose good plans for MY specific needs and took care of my applications over the phone. 1-2-3, eesy-peesy and I was done!! And it didn’t cost me a DIME!!! WOW!!! I HIGHLY recommend Senior Healthcare Solutions for anyone who’s overwhelmed with making the right choices with Medicare Supplemental Insurance and Rx coverage.
