Common Medigap mistakes

Mistakes that are easy to make

Medigap is not complicated once you understand the basics, but a handful of common mistakes can cost real money or limit your options. Nearly every one of them comes down to timing, assumptions, or confusion between different types of coverage. Here are the ones I see, and how to avoid them.

Waiting too long to enroll

The costliest mistake is letting your Medigap Open Enrollment Period pass without a decision. This is the six-month window starting when you are 65 or older and enrolled in Part B. During this window, insurers generally cannot deny you or charge more based on health. After it closes, you may face medical underwriting — which means your health history starts to matter.

If you are approaching 65, put Medigap on the same to-do list as your Part B enrollment. Deciding not to buy is a legitimate choice; missing the window by not deciding is not.

Shopping on premium alone

A low monthly premium today does not always mean lower cost over time. How a company prices its plans matters just as much:

• Attained-age pricing — premiums are based on your current age and rise as you get older
• Issue-age pricing — premiums are based on your age when you bought the policy
• Community-rated pricing — premiums generally do not depend on age

Two companies can quote similar premiums today and behave very differently ten years from now. Understanding the pricing method helps you project what you will pay over time, not just this year.

Assuming the plan letter means the price is fixed

Because Medigap plans are standardized, a given plan letter has the same benefits from every company that sells it. What is not standardized is the premium. Companies can and do charge meaningfully different premiums for the identical plan letter. Comparing quotes across companies for the same letter is one of the simplest things you can do for your budget.

Confusing Medigap with other types of Medicare coverage

Medigap works alongside Original Medicare: Medicare pays its share first, and your Medigap plan helps with the cost-sharing that remains. It generally lets you see any provider who accepts Medicare, anywhere in the country.

There are other ways to receive Medicare benefits through private plans that work under different rules — different networks, different costs, different enrollment periods. They are not the same product, and moving between the two arrangements is not always simple to undo. If you want free, unbiased help understanding the different structures, 1-800-MEDICARE and your local SHINE office (Florida’s free senior insurance counseling program) are good resources.

Canceling old coverage before new coverage is confirmed

Whether you are switching Medigap plans or moving from other coverage, never cancel what you have until a new policy has been approved with a confirmed effective date. A gap in coverage is hard to fix after the fact.

Not revisiting the decision when circumstances change

Your Medigap choice is not carved in stone, but changes after your enrollment window may involve underwriting. If your premium has risen sharply or your needs have changed, it is worth reviewing your options with clear information about what a change would involve — before deciding either way.
