Can I enroll in a Medicare Supplement and a Medicare Part C at the same time?




This is a common question we are asked. The simple answer is NO, you can’t be enrolled in a Medicare Supplement Plan and a Medicare Advantage Plan (Part C) at the same time. These plan types operate differently and are not compatible with each other.


How does a Medicare Supplement Plan work?

Medicare Supplement plans cover the gaps in Original Medicare Parts A and B. Simply put they cover the 20% Medicare does not. Some plans you will be responsible for the Medicare Part B deductible each year. They also do not have any networks and you will need to purchase a stand-alone Prescription Drug Plan. Plan premiums are based on age, zip code and vary by the insurance carrier. As you get older the plan premiums will increase.


How does a Medicare Advantage Plan work?

Medicare Advantage Plans (Medicare Part C) are sometimes called Medicare Replacement Plans. These plans are operated by private insurance companies. They process and provide all the benefits of Original Medicare on Medicare’s behalf. These plans also add additional benefits beyond Medicare such as prescription drug coverage, gym memberships, dental, vision and hearing benefits. Monthly premiums usually start a $0 per month. These plans also will have networks that you need to use unless in an emergency situation. Plans will have copays and maximum out-of-pocket limits per year.


Which plan type is right for me?

Medicare plans are not one size fits all. Many factors such as budget, health, your travel habits and risk tolerance are just a few points to help you make that decision. Meeting with a licensed Perfiniti agent can help you narrow down your choices and project future costs associated with the different plan types.


When can I switch plans?
