Finding the Best Medicare Supplement Plan Letter for Your Client

With 10 different Medicare Supplement plan letters, you may be looking for a simple way to determine which fits best — A, B, C, D, F, G, K, L, M, or N. As is always the case with insurance, it depends on your client’s preferences and circumstances.

Listen to this article:

There’s a time and a place for each plan letter. After you’ve investigated your client’s overall health needs, coverage preferences, budget, and lifestyle enough to determine that a Medicare Supplement plan is the best option, it’s time to choose a standard plan type.

Know Your Letters

The first step to picking the best Med Supp plan is knowing what each plan letter covers. Using a chart like the one below makes this process simple. Keep a copy handy for quick reference.

With so many coverage options, you can feel confident that one of them will be a good fit for your client. Learning the details of each plan letter prepares you for the next step — diving deeper to discover which plan letter is the ideal one for your client.

Ask the Right Questions

The next step to picking the best plan letter is figuring out what’s important to your client and what his/her individual health needs entail. You’ll need to ask them questions to get the full picture. Does your client like to travel? Does she have some financial cushion for out-of-pocket expenses? Does he live in a state that allows excess charges? Will she be visiting the doctor often? Did they become eligible for Medicare before January 1, 2020? Going through the flow chart below will steer you in the right direction in identifying the best fitting plan letter.

Keep in Mind

Before signing a client up for a certain plan letter, make sure your client knows and approves of exactly what will and what won’t be covered. Just because you have a healthy client with money saved for retirement doesn’t always mean Plans A, B, K, or L will be the best fit. That client might want to keep out-of-pocket costs low regardless, so D or G may be a better choice. Keep an open dialogue with your client to ensure a good fit.

Another important note to keep in mind: Since new-to-Medicare clients can’t enroll in plans C and F, the number of people on these plans will dwindle, likely causing premiums to skyrocket. You may want to consider D, G, or N instead.
